summary
This paper investigates one clarification for the constant commentary of a powerful, damaging correlation within the
United States between revenue and weight problems amongst ladies, but not males. We argue key issue is the
gendered expectation that moms are liable for feeding their kids. When revenue is restricted and
households face meals shortages, we predict that an enactment of these gendered norms locations moms at
better danger for weight problems relative to child-free ladies and all males. We undertake an oblique method to review
these advanced dynamics utilizing knowledge on women and men of childrearing age and who’re family heads or
companions within the 1999e2003 waves of the Panel Research of Earnings Dynamics (PSID). We discover Help for our
prediction: Meals insecure moms are extra possible than child-free women and men and meals insecure fathers
to be obese or overweight and to achieve extra weight over 4 years. The dangers are better for single moms
relative to moms in married or cohabiting relationships. Supplemental fashions exhibit that this
sample can’t be attributed to post-pregnancy organic adjustments that predispose moms toweight achieve or
an evolutionary bias towards organic kids. Additional, outcomes are unchanged with the inclusion of bodily
exercise, smoking, consuming, receipt of meals stamps, or Girls, Infants and Youngsters (WIC) dietary
program participation. Weight problems, thus, provides a bodily expression of the vulnerabilities that come up from the
intersection of gendered childcare expectations and poverty.

Students argue that it takes cash to take care of a wholesome weight
in America’s obesogenic atmosphere (Poston & Foreyt, 1999)
as a result of wholesome meals is comparatively costly and calorie-dense,
nutrient-poor meals is reasonable (Drewnowski & Specter, 2004).
Though weight is a operate of each caloric consumption and expenditure, materialist arguments give attention to the prices of meals and predict
better caloric consumption and consequent physique fats amongst low versus
excessive revenue individuals (Glass & McAtee, 2006). Within the U.S., there may be
a powerful, damaging correlation between revenue and the probability of
being obese or overweight, but solely amongst ladies; this isn’t
noticed amongst males (for opinions, see McLaren, 2007; Sobal &
Stunkard, 1989). This intercourse distinction is puzzling, notably to
students who look past particular person explanations to contemplate the
function of shared environments for well being as a result of the bulk of males
and ladies reside collectively (Casper & Bianchi, 2002) and share
socioeconomic assets and weight-related behaviors (French,
Story, & Jeffery, 2001; Mitchell et al., 2003). Given these commonalities, one would count on better similarity between the sexes.
We hypothesize that the important thing distinction is just not between all
ladies and all males, but between moms and non-mothers. We
argue that the confluence of two elements e the expertise of meals
insecurity and the gendered nature of childcare e intersect and
contribute to the noticed intercourse variations within the affiliation of
revenue and physique weight. Meals insecurity is extremely correlated with
poverty (Sarlio-Lähteenkorva & Lahelma, 2001) and happens when
a family faces budgetary constraints that restrict the amount or
high quality of meals they’ll buy (Wunderlich & Norwood, 2006).
But meals insecurity is a “managed course of” (Radimer, 1990),
that means that households strategize and diligently work to keep away from
starvation. That duty, nevertheless, falls extra closely on ladies
given conventional discourses about household life and “ladies’s work”
that place better expectations on ladies for feeding and
nurturing their household, particularly when kids are current
(DeVault, 1991). Provided that meals insecurity is correlated with poor
dietary conduct and weight problems (for a Assessment, see Institute of Drugs,
2011), we assert that meals insecurity mediates the affiliation
between revenue and weight, but that the administration of meals
insecurity intersects with gender to create differential dangers for
weight problems between moms and non-mothers.
To research these dynamics, we research women and men of
childrearing ages (i.e., 18e55) who’re heads or companions of U.S.
households within the 1999, 2001 and 2003 waves of the Panel Research of
Earnings Dynamics (PSID). We check whether or not the affiliation between

family meals insecurity and the probability of being obese
or overweight differs throughout teams outlined by intercourse and parenthood in
cross-sectional fashions of weight standing and longitudinal fashions of
weight change. We additionally study how accomplice co-residence additional
moderates these processes as a result of gendered norms about
parental custody (Coltrane & Adams, 2003) and the better prevalence of meals insecurity amongst single dad and mom (Rose, Gundersen, &
Oliveira, 1998).
Meals insecurity and weight
Family meals safety exists alongside a continuum but will be
categorized right into a four-point ordered scale: meals safe, meals
insufficiency, low meals safety, and really low meals safety (Bickel,
Nord, Value, Hamilton, & Prepare dinner, 2000; Wunderlich & Norwood,
2006). Most People are meals safe, but some face meals insufficiency, that means, they fear about having sufficient cash to purchase
meals for the month, but really make no or few adjustments to their
food regimen (Wunderlich & Norwood, 2006). Meals insecurity happens when
these fears change into a actuality. Low meals safety, or not having the
means to purchase the sorts of meals desired, reduces the standard and
selection of individuals’s diets (Wunderlich & Norwood, 2006). Very low
meals safety happens when individuals do not need the means to purchase the
amount of meals wanted and leads individuals to skip meals and cut back
their meals consumption (Wunderlich & Norwood, 2006). These with both
“low meals safety” or “very low meals safety” are thought-about “meals
insecure” (Wunderlich & Norwood, 2006). In 2009, 14.7% of U.S.
households have been meals insecure (Nord, Coleman-Jensen, Andrews, &
Carlson, 2010), whereas in 2003, the 12 months equivalent to our research,
the prevalence was 11.2% (Nord, Andrews, & Carlson, 2004).
As a result of poverty predicts meals insecurity (Sarlio-Lähteenkorva &
Lahelma, 2001), there are a number of parallels present in analysis on the
function of meals safety for physique weight. Key amongst them are constant
intercourse variations, such that low meals safety is linked to being obese (Adams, Grummer-Strawn, & Chavez, 2003; Dinour, Bergen,
& Yeh, 2007; Lyons, Park, & Nelson, 2008; Townsend, Peerson, Love,
Achterberg, & Murphy, 2001) and gaining 5 kilos or extra in a single
12 months (Wilde & Peterman, 2006), but solely amongst ladies. Very low
meals safety is related to being underweight, but once more solely
for ladies (Wilde & Peterman, 2006).
A number of research recommend that meals insecurity is linked to obese and weight problems on account of administration methods individuals undertake in
the face of financial constraints. Meals insecure people are
extra more likely to eat high-calorie but nutritionally-poor meals to
keep away from emotions of starvation (Dixon, Winkleby, & Radimer, 2001;
Drewnowski & Specter, 2004; Kirkpatrick & Tarasuk, 2008), eat
irregular meals or skip breakfast (Kempson, Keenan, Sadani, Ridlen,
& Rosato, 2002; Ma et al., 2003), and eat much less milk, fruit and
greens, particularly later within the month (Tarasuk, McIntyre, & Li,
2007). In keeping with public well being and vitamin analysis, these
dietary practices are related to being obese (Ledikwe
et al., 2006; Ma et al., 2003) and weight achieve (Berkey, Rockett,
Gillman, Subject, & Colditz, 2003). Within the subsequent part, we element
how the administration of meals insecurity is gendered.
Gender, childcare, and meals insecurity administration
Conventional discourses about “household” life and “ladies’s work”
because the industrial revolution embrace expectations that girls
are liable for caring for his or her members of the family and managing
family duties (Rothman, 1978; Sokoloff, 1980). When kids
are current within the house, these tasks multiply (Hays,
1998) and the gendered division of family labor turns into
extra unequal (Coltrane, 2000). For instance, there may be better
gender fairness within the complete quantity of hours spent on housekeeping in
child-free cohabiting and married than amongst related
with kids (Sanchez & Thomson, 1997; South & Spitze,
1994). Due to this fact, moms usually tend to be subjected to,
internalize, and replicate conventional gender expectations about their
roles and tasks than child-free ladies.
A key female duty is “feeding the household,” which
requires a collection of duties: meal planning, monitoring the availability of
family provisions, buying, cooking, and cleansing (DeVault,
1991). Past the sensible objectives, “feeding the household” additionally
sustains kids’s emotional wants for love, Help and safety
(DeVault, 1991).
In meals insecure houses, moms work exhausting to forestall starvation
amongst their kids. In a qualitative research with ceaselessly meals
insecure younger moms, all insisted that their kids solely skilled meals insufficiency as a result of they adopted a number of methods
to guard them (Stevens, 2010), together with prioritizing their kids’s wants over their very own (McIntyre et al., 2003; Stevens, 2010). As
DeVault notes “[t]hese ladies appear to be expressing a heightened
sense of the extra widespread notion that’s ladies’s personal meals is
much less essential than that ready for others” (1991, p.199). As one
lady in a cash-strapped family famous: “If it will get all the way down to it, we
purchase to feed the youngsters” (DeVault, 1991, p.191).
To handle meals insecurity, moms undertake a range of methods.
Some methods give attention to grocery buying, like shopping for in bulk,
buying at completely different shops to get the most effective costs, or utilizing coupons
(DeVault, 1991; Wiig & Smith, 2008). Different methods contain
moms’ meals consumption. Meals insecure moms skip meals, wait to eat
till later within the day, or eat much less to spare their kids from starvation
and dietary deprivation (Badun, Evers, & Hooper, 1995; DeVault,
1991; McIntyre, Connor, & Warren, 2000; McIntyre et al., 2003). As
a outcome, ladies in meals insecure households are in danger of nutrient
deficiencies in Vitamin A, folate, iron, and magnesium (Tarasuk &
Beaton, 1999). We suspect that these behavioral patterns undergird the unexplained intercourse variations within the affiliation between
meals insecurity and weight (Adams et al., 2003; Dinour et al., 2007;
Lyons et al., 2008; Olson, 1999; Townsend et al., 2001; Wilde &
Peterman, 2006) and why meals insecurity is often not correlated with kids’s weight (Gundersen, Garasky, & Lohman, 2009;
Martin & Ferris, 2007), but for an exception see Gundersen and
Kreider (2009). Sadly we do not need direct measures on
individuals’s dietary conduct or meals insecurity administration practices
to completely discover this sequence, but we do have the requisite knowledge to
check our major speculation:
H1. There’s a statistically vital affiliation between meals
insecurity and being obese or overweight for moms, but not
child-free ladies or all males.
We all know of just one paper about meals insecurity and weight problems
that emphasizes parenthood. With a pattern of dad and mom (65% of
whom have been single moms), Martin and Ferris (2007) discovered
a constructive affiliation between meals insecurity and weight problems, but they
didn’t discover whether or not there was a differential affiliation
between moms and dads. Due to this fact, the present Assessment
makes a big contribution by providing an preliminary check of this
speculation.
The function of marriage and cohabitation
We predict that the dwelling preparations of heterosexual males
and ladies additional situation the variations between moms and
non-mothers. Prior analysis demonstrates that caretaking duties
amongst separated dad and mom are largely carried out by the custodial
father or mother, sometimes the mom (Furstenberg & Cherlin, 1994;
Marsiglio, Amato, Day, & Lamb, 2000). Due to this fact, the dangers of
obese on account of meals insecurity needs to be exacerbated amongst
M.A. Martin, A.M. Lippert / Social Science & Drugs 74 (2012) 1754e1764 1755
single moms and comparatively decrease for moms in co-residential
couple households. Likewise, single fathers needs to be at better
danger of weight problems when they’re meals insecure. Sadly, we have now
too few single fathers in our knowledge to completely discover this risk
as a result of most single dad and mom are single moms (Casper & Bianchi,
2002), reflecting a “neighborhood division of labor” (DeVault, 1991,
p.193) whereby ladies routinely have custody after dad and mom
separate. Our second speculation is:
H2. The affiliation between meals insecurity and being obese or overweight is stronger for single moms versus married or
cohabiting moms.
You will need to be aware, nevertheless, that the causal relationships
between obese, household formation, union dissolution, and
family meals safety are advanced. The truth is, the causal course of
might work in the wrong way: Obese ladies could also be
much less more likely to type unions and bear kids given female magnificence
beliefs emphasizing thinness (Allon, 1982).
Different explanations
We predict that meals insecurity and its administration will increase
the dangers of obese and weight problems for moms given the gendered
expectations of childrearing. We acknowledge, nevertheless, that there are
competing explanations and we do our greatest to handle them.
First, one could agree with our prediction but disagree with our
interpretation. One could contemplate any noticed dangers for moms as
reflecting, not childrearing, but organic dangers of childbearing. If
metabolic adjustments associated to being pregnant predispose beginning moms
to achieve weight, then meals insecure organic moms can be at
better danger of obese and weight problems than “social” moms. Such
variations might additionally come up if, on account of evolutionary pressures,
moms are extra protecting of their organic kids (Daly &
Wilson, 1980). To check whether or not the expertise of being pregnant or
organic kinship creates distinctive dangers, we conduct two supplemental analyses. First, we limit our pattern to solely ladies dwelling
with kids (50% of the pattern) and evaluate whether or not the danger of
weight problems for meals insecure moms is decrease amongst ladies dwelling
with kids they didn’t give beginning to (i.e., they’re adoptive, step,
or foster moms), controlling for the quantity of kids current.
As a result of most girls reside solely with organic kids, statistical
energy points could restrict our capacity to detect a big distinction.
Second, we limit our pattern to ladies who’ve ever given beginning
by 2003 and study whether or not the dangers of family meals insecurity improve as parity will increase, regardless of whether or not their
kids presently reside with her and controlling for her age and
different demographic traits. As a result of 89% of the ladies in
our pattern have given beginning by 2003, energy is much less of an issue in
these analyses. If metabolic adjustments related to being pregnant
undergird our findings, then one would count on these dangers to
accumulate with every beginning and, thus, translate right into a statistically
vital interplay between parity and meals insecurity amongst
organic moms.
Second, one may argue that the statistical affiliation between
meals insecurity and obese is a operate of different sociodemographic elements in addition to revenue. Thus, we management for standing traits, like age, training and race/ethnicity in all fashions.
Third, one may count on that different mediating elements clarify
these patterns, particularly provided that we do not need self-reported
measures of power consumption or, even higher, knowledge from doublylabeled water assessments to measure their power consumption (Schoeller,
1990). We check a number of various mechanisms. As a result of meals
insecure moms could have fewer alternatives for leisure
bodily exercise, we check whether or not variations in self-reported
bodily exercise cut back the affiliation between meals insecurity
and weight amongst moms. We additionally check whether or not the consumption
of alcohol or smoking cigarettes explains the noticed patterns.
As a result of of the stresses related to poverty and meals insecurity
(Huddleston-Casas, Charnigo, & Simmons, 2009), which might
possible really feel extra threatening to oldsters, meals insecure dad and mom might
be extra more likely to self-soothe themselves with alcohol and nicotine.
But these behaviors are related to being obese (Mokdad
et al., 2003; Slattery et al., 1992). Lastly, given the longstanding
debate about whether or not receiving meals stamps (now formally the
Supplemental Vitamin Help Program) will increase the dangers for
obese and weight problems (Borjas, 2004; Gibson, 2003; Institute of
Drugs, 2011), we check whether or not our outcomes change with the
inclusion of meals stamps receipt. We additionally embrace a measure of
participation within the Girls, Infants and Youngsters (WIC) dietary
program.
In sum, we bridge a number of empirical literatures to develop a brand new
theoretical mannequin about how gendered patterns of childcare
intersect with family economics to extend the danger of obese amongst poor, meals insecure moms. We acknowledge that
there are a number of various explanations and, thus, do our greatest to
check them with the obtainable knowledge. Our purpose is to offer an preliminary
examination of whether or not obese and weight problems are bodily
expressions of the vulnerabilities that come up from the intersection of
gender, parenthood, and poverty.
Knowledge and strategies
Knowledge
We use knowledge from the Panel Research of Earnings Dynamics (PSID)
as a result of it’s the solely research that collects knowledge on people’ weight,
revenue, family meals insecurity, and family composition.
Sadly, PSID doesn’t have details about particular person’s
power consumption and meals insecurity administration.
PSID is a longitudinal household-based research that started amassing knowledge in 1968 for a nationally consultant pattern and an
oversample of low-income, Southern households (Hill, 1992). The
PSID accommodates longitudinal knowledge for all people who have been ever in
a PSID family, even when they transfer out (Hill, 1992). Interviews
since 1997 are performed biennially. Provided that the PSID has been
fielded for nearly 50 years, pattern attrition might pose an issue,
but a number of research have discovered that attrition has not affected PSID’s
representativeness (Becketti, Gould, Lillard, & Welch, 1988;
Fitzgerald, Gottschalk, & Moffitt, 1998). PSID is just not consultant,
nevertheless, of immigrant teams arriving within the U.S. after 1968.
We make a number of restrictions to reach at our analytic pattern.
First, we should depend on knowledge collected in 1999, 2001, and 2003, the
years wherein PSID collected knowledge on each weight and meals insecurity. Second, we limit our Assessment to those that have been both the
head of a PSID family or their marital or cohabiting accomplice in
1999, 2001, and 2003 (n ¼ 9935) as a result of PSID solely collects knowledge on
physique weight for these people. Whereas this supplies for
a constant pattern throughout the assorted fashions, it makes the pattern
extra selective with regard to household construction stability. Our
substantive findings are unchanged, nevertheless, in analyses the place
the info are multiply imputed to incorporate anybody who meets the
restrictions listed beneath and was ever within the PSID between 1999
and 2003, regardless of their relationship to the family head.
Third, we limit the Assessment to heads and companions between the
ages of 18 and 55 in 1999 (n ¼ 8151) to give attention to adults most in danger
for dwelling with minor kids and, thus, the hypothesized patterns.
The subsequent two restrictions remove outlier instances that might problem the statistical homogeneity of our Assessment. Fourth, we drop
those that report being overseas born (n ¼ 82) or who will be
moderately assumed to be overseas born as a result of they’ve 5 or
1756 M.A. Martin, A.M. Lippert / Social Science & Drugs 74 (2012) 1754e1764
fewer years of accomplished education (and the minimal age of
obligatory education in the USA is 16) (n ¼ 51). These
people are distinctive in each unobserved and noticed methods (i.e.,
their means and correlations for meals insecurity, quantity of kids, marital standing and weight differ considerably) as a result of the
PSID is just not consultant of immigrants. The absence of immigrants reduces the prevalence of meals insecurity within the research
(Borjas, 2004). Fifth, we omit ladies who’re pregnant on the time
of the 2003 interview (n ¼ 85). Particularly, we omit ladies
reporting a reside beginning within the PSID’s Childbirth and Adoption Historical past
File inside 9 months following their 2003 interview date. After
these restrictions, our pattern is 7931 adults.
Lacking knowledge on account of merchandise non-response is comparatively minor in these
knowledge. There are literally no lacking knowledge for individuals’s intercourse, age, partnership standing, the quantity of co-residential kids, urbanicity, and
family revenue (as a result of the PSID has imputed it). There may be minor
merchandise non-response on meals insecurity (n1999 ¼ 9, n2001 ¼ 11,
n2003 ¼ 20), self-rated well being (n2003 ¼ 86), race (n ¼ 129), and
ladies’s fertility histories (n ¼ 36). The gadgets with probably the most lacking
knowledge are physique mass index (n1999 ¼ 379 [4% of the original 9935
sample], n2001 ¼ 257 [3%], n2003 ¼ 305 [3%]) and training
(n2003 ¼ 596 [6%]). We make the most of a number of imputation deal with merchandise nonresponse, which replaces lacking values with predictions from
info noticed within the pattern (Rubin, 1987). We use the
supplemental program “ice” inside STATA 11.zero (Royston, 2005a,b) to
create 5 imputed knowledge units. The imputation fashions embrace all of
the variables and their interactions which can be used within the empirical
fashions, in addition to the respondent’s work standing, occupation, and
area (all in 2003), the quantity of adults within the family (in 1999,
2001, 2003), whether or not theylive with a younger baby (ages 0e5;in 2003)
and whether or not PSID imputed their revenue. We estimate the empirical
fashions for every imputed knowledge set after which mix the outcomes,
accounting for the variance inside and between the imputed
samples to calculate the coefficients’ customary errors (Rubin, 1987).
Measures
Physique weight
We decide individuals’s weight classification in three steps. First,
as a result of PSID solely has self-reported weight and since selfreported weight is usually biased downward amongst ladies and
upward amongst males (Cawley & Burkhauser, 2006), we use the
Cawley (2004; Cawley & Burkhauser, 2006) changes to enhance
the accuracy of our dependent variable. Particularly, we multiply
respondents’ self-reported weight by race- and sex-specific coefficients from Cawley’s regressions of measured weight on selfreported weight. Second, we calculate their physique mass index
(BMI) [weight (kg)/height2 (m2
)] from their self-reported peak and
their Cawley-adjusted self-reported weight. Third, we comply with World
Well being Group (2000) pointers to categorise BMI into the
following weight classes: underweight (BMI < 18.5), regular
weight (18.5 BMI < 25), obese (25 BMI < 30) and overweight
(BMI 30). Within the cross-sectional fashions, we predict whether or not
an individual is (1) regular weight or underweight, (2) obese, or (three)
overweight in 2003. As a result of lower than 2% of the pattern is underweight,
we can’t mannequin underweight as a separate class. For the
longitudinal fashions, we predict their weight change (in kilos)
between 1999 and 2003, merely calculated as their Cawley-adjusted
2003 weight minus their Cawley-adjusted 1999 weight.
Family meals insecurity
We use the U.S. Division of Agriculture’s Meals Safety Scale
(Bickel et al., 2000). Respondents have been requested a sequential collection of
18 questions in the event that they reside with kids and 10 questions in the event that they do
not. The completely different collection are made equal (and thus orthogonal
to the presence of kids) within the last 10-point scale and categorical measure of meals safety. Following the USDA’s pointers,
households are categorized as meals insecure (¼1) in the event that they rating a 2.2 or
larger on the Meals Safety Scale (Bickel et al., 2000). We measure
their family meals insecurity in 2003 and create a longitudinal
measure that counts the survey years with reported family
meals insecurity between 1999 and 2003 (values: zero, 1, 2, or three).
Intercourse
Intercourse is a dichotomous indicator for whether or not the particular person is feminine
(1 ¼ sure) or male.
Youngsters
PSID contributors report the quantity of kids between the
ages of zero and 17 years presently within the family, regardless of
their organic relationship to the family head or their accomplice.
We create a dichotomous measure indicating kids are current
(¼1) and a depend of kids current.
We use the PSID’s Childbirth and Adoption Historical past (1985e2007)
knowledge to create two variables. First, amongst these dwelling with kids
in 2003, we decide whether or not the girl gave beginning to each
baby current and create a dichotomous variable equal to 1 if she
didn’t. As a result of only a few ladies reside with a mixture of organic and
non-biological kids (N ¼ 14), the outcomes primarily replicate
whether or not ladies who didn’t give beginning to any of the kids
current (N ¼ 307) are completely different. Second, we calculate the entire
quantity of kids a girl has ever borne.
Within the longitudinal fashions, we use a variable that equals the
distinction between the quantity of kids current in 2003 and 1999.
Companion co-residence
To check adults in several residential relationships, we
estimate fashions individually for individuals who are single and those that
are who’re dwelling with a romantic accomplice, whether or not married or
cohabiting.
Different mediating variables
Supplemental fashions embrace the next variables, reported
in 2003: being a “present smoker” (¼1), the quantity of alcoholic
drinks consumed per day (zero ¼ none, 1 ¼ lower than one a day, 2 ¼ 1 to
2 per day, three ¼ three to four a day, and four ¼ 5 or extra a day), bouts of
“heavy” bodily exercise over the past month (PSID-provided
examples embrace aerobics, working, swimming, strenuous housekeeping), bouts of “mild” bodily exercise over the past month
(PSID-provided examples embrace strolling, , gardening,
bowling), receipt of meals stamps in 2001 (¼1), and receipt of WIC in
2002 (¼1).
Management variables
To manage for confounding variables, we embrace age (in years),
training (in years of accomplished education), poor self-rated well being
(zero ¼ “good,” “excellent,” or “wonderful,” 1 ¼ “poor” or “truthful”),
incapacity standing (1 ¼ at the least one limitation within the Actions of Day by day
Dwelling Scale, zero ¼ none), and metropolitan residence (zero ¼ nonmetropolitan space, 1 ¼ metropolitan space). Race is measured with
three dichotomous variables to match (1) non-Hispanic African
People, (2) Hispanics, and (three) non-Hispanic different racial teams
to non-Hispanic Whites (the reference class).
Assessment
For the cross-sectional Assessment, we estimate a number of ordinal
logistic regression fashions in STATA (v. 11) to foretell 2003 weight
classes. The outcomes are substantively just like these from
multinomial logistic regression fashions. (Outcomes obtainable upon
