A Comparison of Food Insecurity Prevalence among Students Attending Minority Serving Compared with Predominantly White Institutions in Prephase, Earlier, and Later Phases of the COVID-19 Pandemic.

BACKGROUND: College students have a high prevalence of food insecurity, and descriptive reports suggest even higher rates at minority-serving institutions than those at predominantly White institutions. These institutional inequities in food insecurity among college students based on minority designation may have shifted owing to the COVID-19 pandemic. OBJECTIVES: We aimed to compare the prevalence of food insecurity between students at minority serving and predominantly White institutions during 3 phases: prepandemic [Fall 2019-Spring 2020 (February 2020)], earlier pandemic (Fall 2020-Spring 2021), and later pandemic (Fall 2021-Spring 2022). METHODS: Our study included repeated cross-sectional samples from the American College Health Association-National College Health Assessment III (N = 287,221 students, 354 institutions). We performed multivariable Poisson regression with cluster-robust SEs to estimate associations between institutional minority designation and food insecurity, with 1 model for each pandemic phase. RESULTS: Students attending minority serving compared with predominantly White institutions had a higher prevalence of food insecurity overall (42% compared with 37%) and within each pandemic phase. After adjusting for sociodemographic and institutional characteristics, students at minority serving institutions had 23% higher food insecurity prevalence during the prepandemic phase than students at predominantly White institutions (95% confidence interval: 1.14, 1.32). Associations were null for earlier and later pandemic phases. CONCLUSIONS: Lower institutional inequities in food insecurity after the onset of the pandemic may reflect more students returning home as well as an increase in social safety net programs. Regardless of cause, the high prevalence of food insecurity among students, especially at minority serving institutions, underscores the importance of addressing food insecurity at postsecondary campuses.

Trends in Food Insecurity Among Households with Children Participating in WIC and SNAP in California, 2005-2017.

OBJECTIVES: To assess trends in food insecurity between 2005 and 2017-a period including the Great Recession-by participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). METHODS: Data from the California Health Interview Survey (CHIS), 2005-2017, were used, including 7421 households: WIC participants (n = 4184)-those participating in WIC only (n = 2315) and in the Supplemental Nutrition Assistance Program (SNAP) in addition to WIC (n = 1869)-and WIC-eligible non-participants (n = 3237). Multivariable logistic regression models were run with food insecurity as the outcome, WIC participation and survey year as predictors, and adjusted by children's and family's demographic and socioeconomic variables. Interactions between WIC participation and survey year were tested. RESULTS: WIC + SNAP participating households had higher crude food insecurity prevalence across time compared to WIC only and WIC-eligible non-participant households. In fully adjusted models: (1) food insecurity was higher between 2009 and 2017, compared to 2005, for all groups; (2) WIC participating households had higher odds of food insecurity than WIC-eligible non-participants (OR = 1.23, 95%CI = 1.10-1.38); (3) when WIC participants were split into WIC only and WIC + SNAP, WIC + SNAP households had higher odds of food insecurity than WIC-eligible non-participants (OR = 1.45, 95%CI = 1.27-1.66); and (4) the association between food insecurity and WIC participation did not change across time (interaction p-value > 0.10). CONCLUSIONS: Food insecurity increased post-Great Recession among low-income households with children in California, with those participating in WIC, particularly in WIC + SNAP, at higher risk. WIC should consider additional referrals for households who participate in WIC + SNAP.

The association between language use and food insecurity among Hispanic adults residing in the USA depends on nativity.

OBJECTIVE: To examine the association between language use - predominantly English, English and Spanish equally and predominantly Spanish - and food insecurity among Hispanic adults residing in the USA, 1999-2018. DESIGN: Pooled cross-sectional study design. SETTING: United States. PARTICIPANTS: 15 073 Hispanic adults. RESULTS: Compared with Hispanic adults who predominantly spoke English and after adjusting for age, sex, family income-to-poverty ratio, education level and employment status, Hispanic adults who spoke English and Spanish equally (OR = 1·28, 95 % CI = 1·05, 1·56) or predominantly Spanish (OR = 1·25, 95 % CI = 1·04, 1·49) had higher odds of food insecurity. After stratifying by country of birth, language use was associated with higher odds of food insecurity only for Hispanic adults born outside of the USA, but not for Hispanic adults born in the USA. Hispanic adults born outside of the USA who spoke English and Spanish equally (OR = 1·27, 95 % CI = 1·04, 1·55) or spoke predominantly Spanish (OR = 1·24, 95 % CI = 1·04, 1·48) had higher odds of food insecurity when compared with those who predominantly spoke English. CONCLUSION: Foreign-born Hispanic adults who speak predominantly Spanish, or English and Spanish equally, have higher odds of food insecurity. Food and nutrition assistance programmes that serve Hispanic immigrants should make sure to provide linguistically and culturally appropriate services to this population.

Water insecurity, self-reported physical health, and objective measures of biological health in the Peruvian Amazon.

OBJECTIVES: This study examines the associations between water insecurity, self-reported physical health, and objective measures of biological health among 225 Awajún adults (107 women; 118 men) living in the Peruvian Amazon, a "water-abundant" region. METHODS: A survey, which included multiple measures of self-reported physical health, and objective measures of biological health such as blood pressure and nutritional and immune biomarkers. RESULTS: Greater water insecurity was associated with multiple measures of self-reported physical health, including higher incidence of reported diarrhea, nausea, back pain, headaches, chest pain, fatigue, dizziness, overall poor perceived health, and "being sick." These symptoms align with the physical strain associated with water acquisition and with drinking contaminated water. A significant association between higher water insecurity and lower systolic blood pressure emerged, which may be linked to dehydration. None of the other biomarkers, including those for nutrition, infection, and stress were significantly associated with water insecurity scores. CONCLUSIONS: These analyses add to the growing body of research examining the associations between water insecurity and health. Biocultural anthropologists are well-positioned to continue probing these connections. Future research will investigate relationships between measures of water insecurity and biomarkers for gastrointestinal infection and inflammation in water-scarce and water-abundant contexts.

Determinants of food insecurity among households with children in Villa el Salvador, Lima, Peru: the role of gender and employment, a cross-sectional study.

BACKGROUND: From 2014-2019, Latin America and the Caribbean had the fastest growth of moderate-to-severe food insecurity than any other region, rising from 22.9% to 31.7%. While the prevalence of food insecurity is higher among women than men in every continent, Latin America has the largest food insecurity gender gap. Factors contributing to this gender inequity include underrepresentation of women in formal employment, heightened burden of dependent care on women, and unequal compensation of labor for women vs. men. The objective of this study was to investigate the association between the gender of the head of the household, employment status of household members, and food insecurity in households with children in a low-income district of Lima, Peru. METHODS: This cross-sectional study was carried out in Villa El Salvador, the fifth largest district in Metropolitan Lima, Peru, where over 20% of the population lives in poverty. Data were collected on a stratified random sample (n = 329) using a household questionnaire, including a validated food security tool (HFIAS). We ran multivariate logistic regression models predicting household food insecurity, with independent variables including gender of household head, education of household head, employment of household head, household-level employment status, age, and weekly food expenses per person. RESULTS: In fully adjusted models, woman-headed households had almost thrice the odds of being food insecure compared to man-headed households. Education also had a significant effect size: a household whose household head did not complete high school was 3.4 times more likely to be food insecure than if they had some post-secondary education. Woman-headed households had a significantly higher proportion of members not formally employed, compared to man-headed households, but employment status was not associated with food insecurity. CONCLUSIONS: Gender of the household head was a major contributing factor to household food insecurity in Villa el Salvador. Gender dynamics affecting opportunities for employment, education, and non-remunerated work should inform national food security policies and interventions with the goal to not only lower food insecurity, but also reduce gender inequities in food insecurity and other nutritional outcomes.

Food insecurity and food consumption among children who receive federal food assistance.

The objective of this study was to investigate the association between household food insecurity and food intake among children who participated in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), including a sub-sample who also participated in the Supplemental Nutrition Assistance Program (SNAP). Data came from the 2014 and 2017 Los Angeles County WIC Surveys, involving a random sample of WIC participating families in Los Angeles, California. Outcome variables were average daily consumption of fruit, 100% fruit juice, vegetables, milk, other juice, other sweetened drinks, and sweet foods, and frequency of fast-food consumption, as reported by the child's caregiver. Our predictor was household food insecurity, obtained from the 6-item Household Food Security Survey Module. Poisson regression (fruit, 100% fruit juice, vegetables, and milk), Negative Binomial regression (other juice, other sweetened drinks, and sweet foods) and multinomial logistic regression (frequency of fast food) models were run, adjusting for child's age and sex; maternal age, ethnicity and language, education, and employment; and type of WIC participation (WIC only vs. WIC + SNAP). In fully adjusted models, household food insecurity was associated with higher consumption of 100% fruit juice (RR = 1.08, 95%CI = 1.03-1.11), milk (RR = 1.04, 95%CI = 1.01-1.07), other juice (RR = 1.16, 95%CI = 1.08-1.26), other sweetened drinks (RR = 1.28, 95%CI = 1.12-1.46), and sweet foods (RR = 1.09, 95%CI = 1.04-1.14). No significant associations were found between household food insecurity and fruit and vegetable consumption. Nutrition education provided by WIC should continue to emphasize the importance of consuming fresh foods, while limiting foods high in sugar for this young population. Efforts should be made to identify food insecure families at the point of service delivery for enhanced nutrition education and social services referrals.

Differences in Early Childhood Dietary Behaviors by Infant Feeding Type and Sex.

BACKGROUND: Type of infant feeding has been linked to later nutritional outcomes, including dietary diversity and obesity in childhood. Little is known about how introduction to complementary feeding and diet quality in early childhood vary by infant feeding type and sex. OBJECTIVE: Our objective was to investigate whether early childhood dietary patterns vary by infant feeding type and sex. METHODS: Data from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Infants and Toddler Feeding Practices Study 2 (ITFPS-2) was used, including children with complete information on the WIC infant food package received at ages 1, 7, and 11 mo (N = 2839). Based on this information, children were grouped as fully breastfed, mostly breastfed, mostly formula fed, and fully formula fed. Outcomes include introduction of complementary foods; caloric intake aged between 1 and 36 mo; and Healthy Eating Index (HEI)-2015 between 13 and 36 mo. Mixed models were used adjusting for child's, mother's, and family's sociodemographic characteristics. RESULTS: Across all infant feeding groups, the mean age of introduction to any solids was before the age of 6 mo; fully breastfed children were introduced to complementary foods closer to the recommended age (mean 5.1-5.2 mo) compared with other feeding groups (mean 4.6-4.8 mo). Fully formula fed infants consumed significantly more energy than fully breastfed infants at ages 1 mo (boys = 55 kcal/d, girls = 47 kcal/d), 12 mo (boys = 68 kcal/d, girls = 59 kcal/d), 24 mo (boys = 81 kcal/d, girls = 71 kcal/d), and 36 mo (boys = 95 kcal/d, girls = 83 kcal/d). No meaningful differences were observed for HEI-2015 between infant feeding groups or child sex, with average scores of HEI-2015 for all children being 61-63 out of 100. CONCLUSION: Early childhood dietary patterns were slightly better among children who were fully breastfed as infants, compared with children in other infant feeding groups. The diets of all WIC-participating children could be improved.

The role of income and neighbourhood poverty in the association between the 2009 Special Supplemental Nutrition Program for Women, Infants and Children (WIC) food package change and child obesity among WIC-participating children in Los Angeles County, 2003-2016.

OBJECTIVE: To determine whether a previously reported association between the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) food package change and reduced child obesity risk among WIC-participating children in Los Angeles County holds across levels of family income and neighbourhood poverty. DESIGN: Analysis of prospectively collected WIC administrative data. The outcome was obesity at age 4 years (BMI-for-age ≥ 95th percentile). Poisson regression was applied to a matched sample (n 79 502) to determine if the association between the WIC food package change and child obesity was modified by family income (<50 % federal poverty level (FPL), 50-100 % FPL, >100 % but <185 % FPL) and neighbourhood poverty. SETTING: Los Angeles County, California. PARTICIPANTS: Children who participated in WIC in Los Angeles County between 2003 and 2016; children were grouped as receiving the old WIC food package (2003-2009) or the new WIC food package (2010-2016). RESULTS: Receiving the new WIC food package (i.e., post-2009) was associated with 7-18 % lower obesity risk across all family income categories. Neither family income nor neighbourhood poverty significantly modified the association between the WIC food package and child obesity. However, certain sub-groups seemed to benefit more from the food package change than others. In particular, boys from families with income above poverty but residing in the poorest neighbourhoods experienced the greatest reductions in obesity risk (relative risk = 0·77; 95 % CI 0·66, 0·88). CONCLUSIONS: The WIC food package revisions were associated with reduced childhood obesity risk among all WIC-participating families in Los Angeles County, across levels of income eligibility and neighbourhood poverty.

The new child food package is associated with reduced obesity risk among formula fed infants participating in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) in Los Angeles County, California, 2003-2016.

BACKGROUND: The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) changed the food packages provided to its participants in 2009, to better align them with the Dietary Guidelines for Americans. Previous research found that the 2009 WIC food package change was associated with reduced obesity risk, particularly among breastfed infants but also among those who were never breastfed. The objective of this study was to determine if the new child food package introduced in 2009, including more produce and whole grains for 1-4-year old children, was associated with healthier growth trajectories and reduced obesity risk at age 4 years among children who were exclusively formula fed during infancy. METHODS: Administrative data on WIC-participating children in Los Angeles County, 2003-2016, were used (N = 74,871), including repeated measures of weight and length (or height); child's age, gender, and race/ethnicity; maternal education and language; and family poverty. Gender-stratified spline mixed models were used to examine weight-for-height z-score (WHZ) growth trajectories from 0 to 4 years and Poisson regression models were used to assess obesity (BMI-for-age > 95th percentile) at age 4. The main independent variable was duration of receipt (dose) of the new child package, categorized as 0, > 0 to < 1, 1 to < 2, 2 to < 3, 3 to < 4, and 4 years. RESULTS: WHZ growth trajectories were similar for children across new child package dose groups. Boys and girls who were fully formula fed during infancy but received the new child food package for 4 years had a 7% (RR = 0.93; 95%CI = 0.89-0.98) and a 6% (RR = 0.94; 95%CI = 0.89-0.99) lower obesity risk, respectively, compared to children who received the new child food package for 0 years. There were no differences in obesity risk for children receiving < 4 years of the new child package vs. 0 years. CONCLUSIONS: Providing healthy foods during childhood to children who were exclusively formula fed as infants was associated with modest improvements in obesity outcomes. While breastfeeding promotion should still be prioritized among WIC participants, providing healthy foods during childhood may provide health benefits to formula fed children, who comprise a sizeable proportion of children served by WIC.

The neighborhood food environment modifies the effect of the 2009 WIC food package change on childhood obesity in Los Angeles County, California.

BACKGROUND: Food packages provided by the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were revised in 2009 to better align them with the Dietary Guidelines for Americans. This study was conducted to evaluate whether the effect of the food package change on childhood obesity varied by the food environment in the neighborhoods where WIC-participating children live. METHODS: Administrative data from participating children in Los Angeles County, California (2003-2016) were merged with geocoded food vendor information by neighborhood of residence. Obesity risk at age 4 was compared between children receiving old (2003-2009) and new (2010-2016) WIC food packages using sex-stratified Poisson regression models, with interaction terms between WIC package and neighborhood density (number per square mile) of healthy and unhealthy food outlets. RESULTS: The new food package was associated with a significant decrease in obesity risk. Among boys, the new food package was associated with 8 to 18% lower obesity risk at all healthy and unhealthy food outlet densities, and the association was not modified by neighborhood food outlet density. Among girls, the association of the new food package with obesity risk was protective in neighborhoods with high healthy and low unhealthy food outlet densities, and adverse in neighborhoods with high unhealthy and low healthy food outlet densities. The effect of the new food package among girls was modified by unhealthy food outlet density, with significantly smaller (p-value = 0.004) decreases in obesity risk observed in neighborhoods with higher unhealthy food outlet density. CONCLUSIONS: The impact of the food package change was modified by the neighborhood food environment among girls only. Future policy changes should incorporate consideration of ways to mitigate potentially inequitable geographic distribution of the health benefits of policy changes.

Neighborhood deprivation and biomarkers of health in Britain: the mediating role of the physical environment.

BACKGROUND: Neighborhood deprivation has been consistently linked to poor individual health outcomes; however, studies exploring the mechanisms involved in this association are scarce. The objective of this study was to investigate whether objective measures of the physical environment mediate the association between neighborhood socioeconomic deprivation and biomarkers of health in Britain. METHODS: We linked individual-level biomarker data from Understanding Society: The UK Household Longitudinal Survey (2010-2012) to neighborhood-level data from different governmental sources. Our outcome variables were forced expiratory volume in 1 s (FEV1%; n=16,347), systolic blood pressure (SBP; n=16,846), body mass index (BMI; n=19,417), and levels of C-reactive protein (CRP; n=11,825). Our measure of neighborhood socioeconomic deprivation was the Carstairs index, and the neighborhood-level mediators were levels of air pollutants (sulphur dioxide [SO2], particulate matter [PM10], nitrogen dioxide [NO2], and carbon monoxide [CO]), green space, and proximity to waste and industrial facilities. We fitted a multilevel mediation model following a multilevel structural equation framework in MPlus v7.4, adjusting for age, gender, and income. RESULTS: Residents of poor neighborhoods and those exposed to higher pollution and less green space had worse health outcomes. However, only SO2 exposure significantly and partially mediated the association between neighborhood socioeconomic deprivation and SBP, BMI, and CRP. CONCLUSION: Reducing air pollution exposure and increasing access to green space may improve population health but may not decrease health inequalities in Britain.

Maternal pre-pregnancy BMI and offspring body composition in young adulthood: the modifying role of offspring sex and birth order.

OBJECTIVE: To investigate if the association between maternal pre-pregnancy BMI and offspring's body composition in late adolescence and young adulthood varies by offspring birth order and sex. DESIGN: Family cohort study, with data from registers, questionnaires and physical examinations. The main outcome under study was offspring body composition (percentage fat mass (%FM), percentage lean mass (%LM)) measured by dual-energy X-ray absorptiometry. SETTING: Uppsala, Sweden. SUBJECTS: Two hundred and twenty-six siblings (first-born v. second-born; average age 19 and 21 years) and their mothers. RESULTS: In multivariable linear regression models, maternal pre-pregnancy BMI was positively associated with daughter's %FM, with stronger estimates for first-born (ß=0·97, 95 % CI 0·14, 1·80) v. second-born daughters (ß=0·64, 95 % CI 0·08, 1·20). Mother's BMI before her first pregnancy was associated with her second-born daughter's body composition (ß=1·05, 95 % CI 0·31, 1·79 (%FM)) Similar results albeit in the opposite direction were observed for %LM. No significant associations were found between pre-pregnancy BMI and %FM (ß=0·59, 95 % CI-0·27, 1·44 first-born; ß=-0·13, 95 % CI-0·77, 0·52 second-born) or %LM (ß=-0·54, 95 % CI-1·37, 0·28 first-born; ß=0·11, 95 % CI-0·52, 0·74 second-born) for sons. CONCLUSIONS: A higher pre-pregnancy BMI was associated with higher offspring %FM and lower offspring %LM in late adolescence and young adulthood, with stronger associations for first-born daughters. Preventing obesity at the start of women's reproductive life might reduce the risk of obesity in her offspring, particularly for daughters.

Early life characteristics, social mobility during childhood and risk of stroke in later life: findings from a Swedish cohort.

AIMS: To investigate if early life characteristics and social mobility during childhood are associated with incident thrombotic stroke (TS), haemorrhagic stroke (HS) and other stroke (OS). METHODS: Our study population consists of all live births at Uppsala University Hospital in 1915-1929 (Uppsala Birth Cohort; n = 14,192), of whom 5532 males and 5061 females were singleton births and lived in Sweden in 1964. We followed them from 1 January 1964 until first diagnosis of stroke (in the National Patient Register or Causes of Death Register), emigration, death, or until 31 December 2008. Data were analysed using Cox regression, stratifying by gender. RESULTS: Gestational age was negatively associated with TS and OS in women only. Women had increased risk of TS if they were born early preterm (<35 weeks) (HR 1.54 (95% CI 1.02-2.31)) or preterm (35-36 weeks) (HR 1.37 (95% CI 1.03-1.83)) compared to women born at term. By contrast, only women who were early preterm (HR 1.98 (95% CI 1.27-3.10) had an increased risk of OS. Men who were born post-term (⩾42 weeks) had increased risk of HS (HR 1.45 (95% CI 1.04-2.01)) compared with men born at term, with no association for women. TS was associated with social mobility during childhood in women: women whose families were upwardly or downwardly mobile had increased risk of TS compared to women who were always advantaged during childhood. CONCLUSIONS: Gestational age and social mobility during childhood were associated with increased risk of stroke later in life, particularly among women, but there was some heterogeneity between stroke subtypes.

Childhood family structure and women's adult overweight risk: A longitudinal study.

AIM: The aim of this study was to investigate whether women's adult overweight and obesity risk was associated with their childhood family structure, measured as their mothers' marital status history, during the women's first 18 years of life. METHODS: Using linked register data, we analyzed 30,584 primiparous women born in Sweden in 1975 who were between 19-35 years of age when their height and pre-pregnancy weight was recorded. The outcomes were women's overweight/obesity (body mass index (BMI) ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2) and the predictor was mothers' marital status history, which was summarized using sequence analysis. We carried out nested logistic regression models adjusting for women's age and maternal sociodemographic characteristics. RESULTS: Mothers' marital status history was summarized into six clusters: stable marriage, stable cohabitation, married then divorcing, cohabiting then separating, varied transitions, and not with father. In fully adjusted models and compared with women whose mothers belonged to the stable marriage cluster: (1) women whose mothers belonged to the other marital status clusters had higher odds of overweight/obesity (odds ratio (OR) ranging 1.15-1.19; p < 0.05); and (2) women whose mothers belonged to the stable cohabitation (OR = 1.31; 95% confidence interval (CI) = 1.14-1.52), cohabiting then separating (OR = 1.23; 95% CI = 1.01-1.49), varied transitions (OR = 1.24; 95% CI = 1.11-1.39), and not with father (OR = 1.24; 95% CI = 1.00-1.54) clusters had higher odds of obesity. CONCLUSIONS: Women whose mothers were not in stable marriage relationships had higher odds of being overweight or obese in adulthood. The finding that even women raised in the context of stable cohabitation had higher odds of being overweight or obese is intriguing as these relationships are socially accepted in Sweden.

The unhealthy food environment does not modify the association between obesity and participation in the Supplemental Nutrition Assistance Program (SNAP) in Los Angeles County.

BACKGROUND: Participation in the Supplemental Nutrition Assistance Program (SNAP) has been linked to an increased risk of obesity, but not much is known about the mechanisms behind this association. The objective of this study was to determine if the neighborhood density of unhealthy food outlets modifies the association between obesity and participation in SNAP. METHODS: Data comes from the first wave of the Los Angeles Family and Neighborhood Survey; included are a subsample of adults (18+ years) who were SNAP participants or eligible non-participants (N = 1,176). We carried out multilevel analyses with obesity (BMI ≥ 30 Kg/m2), SNAP participation, and the neighborhood density of unhealthy food outlets as dependent, independent and modifying variables, respectively, controlling for age, gender, race/ethnicity, marital status, working status, mental health, and neighborhood poverty. RESULTS: SNAP participants had double the odds of obesity compared to eligible non-participants (OR = 2.02; 95%CI = 1.44-2.83). However, the neighborhood density of unhealthy food outlets did not modify this association. CONCLUSIONS: SNAP participation was associated with higher odds of obesity in our primarily Hispanic sample in Los Angeles County, with no effect modification found for the unhealthy portion of the food environment. More research is needed with additional food environment measures to confirm our null findings. Additional research is needed to elucidate the mechanisms linking SNAP participation and obesity as they remain unclear.

Regional inequalities in pre-pregnancy overweight and obesity in Sweden, 1992, 2000, and 2010.

AIMS: To investigate regional differences and time trends in women's overweight and obesity in Sweden. METHODS: Using data from the Swedish Medical Birth Register (women aged ⩾18 years, first pregnancy only) and the Total Population Register accessed through the Umeå SIMSAM Lab, age-standardized prevalence of pre-pregnancy overweight/obesity (BMI ⩾ 25 kg/m(2)) and obesity (BMI ⩾ 30 kg/m(2)) were estimated by county for the years 1992, 2000, and 2010. Maps were created using ArcMap v10.2.2 to display regional variations over time and logistic regression analyses were used to assess if the observed trends were significant. RESULTS: The prevalence of pre-pregnancy overweight/obesity and obesity increased significantly in all Swedish counties between 1992, and 2010. In 2010, Södermanland and Gotland exhibited the highest age-standardized overweight/obesity (39.7%) and obesity (15.1%) prevalence, respectively. The sharpest increases between 1992 and 2010 were observed in Västerbotten for overweight/obesity (75% increase) and in Gotland for obesity (233% increase). Across the years, Stockholm had the lowest prevalence of overweight/obesity (26.3% in 2010) and obesity (7.3% in 2010) and one of the least steep increases in prevalence of both between 1992 and 2010. CONCLUSIONS: Substantial regional differences in pre-pregnancy overweight and obesity prevalence are apparent in Sweden. Further research should elucidate the mechanisms causing these differences.

The new food package and breastfeeding outcomes among women, infants, and children participants in Los Angeles County.

OBJECTIVES: We assessed the effect of the new Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food package, implemented in October 2009, on breastfeeding outcomes among a predominately Latina sample of WIC participants in Los Angeles County, California. METHODS: We used data from 5020 WIC participants who were interviewed in a series of repeated cross-sectional surveys conducted in 2005, 2008, and 2011. Participants were randomly selected from Los Angeles County residents who received WIC services during those years. RESULTS: Consistent with the WIC population in Los Angeles, participants were mostly Latina and had low levels of income and education; more than half were foreign-born. We found small but significant increases from pre- to postimplementation of the new WIC food package in prevalence of prenatal intention to breastfeed and breastfeeding initiation, but no changes in any breastfeeding at 3 and 6 months. The prevalence of exclusive breastfeeding at 3 and 6 months roughly doubled, an increase that remained large and significant after adjustment for other factors. CONCLUSIONS: The new food package can improve breastfeeding outcomes in a population at high risk for negative breastfeeding outcomes.

Time-Trends in Food Insecurity Among US-Born and Foreign-Born Hispanic Adults by Language Use: An Analysis of National Health and Nutrition Examination Survey Data, 1999-2018.

BACKGROUND: Historically, food insecurity prevalence has been higher in Hispanic households than in non-Hispanic White households. Food insecurity prevalence among Hispanic adults, US-born and foreign-born, may vary by language use. OBJECTIVE: To explore whether or not the relationship between language use and food insecurity varied over time (1999-2018) among US-born and foreign-born Hispanic adults. DESIGN: Trends analysis and multivariable logistic regression modeling using pooled cross-sectional data. PARTICIPANTS AND SETTING: Fifteen thousand sixty-two Hispanic adults participating in the United States National Health and Nutrition Examination Survey (1999-2018). MAIN OUTCOME MEASURES: Food insecurity prevalence, assessed with the US Household Food Security Survey Module. STATISTICAL ANALYSIS: Unadjusted food insecurity trends from 1999 to 2018 by language use (mostly English, both languages equally, or mostly Spanish) among US-born and foreign-born Hispanic adults were analyzed using piecewise-linear regression of log prevalence rates. Multivariable logistic regression models adjusted for sociodemographic characteristics and with an interaction term between language use and time were used to determine if odds of food insecurity among US-born and foreign-born Hispanic adults varied by language use between 1999 and 2018. RESULTS: Hispanic adults' food insecurity prevalence followed an upward linear trend from 1999 to 2018; this was significant for US-born mostly English-speakers (P < 0.001), US-born mostly Spanish-speakers (P = 0.013), and foreign-born mostly Spanish-speakers (P < 0.001). In fully adjusted logistic regression models, foreign-born Hispanic adults who spoke both languages equally (odds ratio 1.8, 95% CI 1.2 to 2.6) and those who spoke mostly Spanish (odds ratio 1.9, 95% CI 1.4 to 2.8) had significantly higher food insecurity odds, compared with mostly English-speakers. No variations in associations across time were observed between language use and food insecurity (interaction P value > 0.1). CONCLUSIONS: Hispanic adults' unadjusted food insecurity trends from 1999 to 2018 varied by language use. When adjusted for sociodemographic characteristics and compared with mostly English-speakers, food insecurity odds were significantly higher only among foreign-born Hispanic adults who spoke either both languages equally or mostly Spanish. Food assistance programs should linguistically adapt their services for Hispanic adults.

Nutrient-Dense African Indigenous Vegetables and Grains in the FAO Food Composition Table for Western Africa (WAFCT) Identified Using Nutrient-Rich Food (NRF) Scores.

Nutrient profiling (NP) models that assess nutrient density of foods can help remedy micronutrient deficiencies. We used NP methods to identify the most nutrient-rich foods in the 2019 FAO/INFOODS Western Africa Food Composition Table (WAFCT). The WAFCT had complete data for 909 foods. Three versions of the well-established Nutrient-Rich Food (NRF) model were used: (1) the original NRF9.3 based on 9 micronutrients (protein, fiber, calcium, iron, potassium, magnesium, vitamin A, vitamin C, and vitamin D); (2) a new NRF6.3 based on 6 priority micronutrients (iron, zinc, calcium, folate, vitamin A, vitamin B12); and (3) NRF 15.3, based on 15 nutrients to encourage (NRF6.3 nutrients + vitamin D, vitamin E, vitamin C, vitamin B1, vitamin B2, vitamin B3, vitamin B6, copper, and magnesium). Data analyses used one-way ANOVAs and independent t-tests, with significance at α = 0.05. Animal-source foods were rated higher by NRF6.3 priority micronutrient and NRF15.3 NP models than by the NRF9.3 model. African indigenous vegetables had higher protein content and higher nutrient density compared to non-indigenous vegetables, and African indigenous grains had higher nutrient density compared to non-indigenous grains. Though animal-source foods received some of the highest scores, NP models adapted to the West African context showed that African indigenous vegetables and grains were also nutrient rich. Indigenous foods could be important sources of priority micronutrients for the region.

Impact of county and state immigration policies on immigrant household enrollment in the supplemental nutrition assistance program.

Introduction: Low-income immigrants who are eligible to participate in the Supplemental Nutrition Assistance Program (SNAP) participate at lower rates compared to non-immigrants. Immigrant households may be more likely to participate in SNAP if they live in areas with policies that integrate them into society and protect them from deportation. Methods: Data on low-income immigrant households came from the 2019 American Community Survey (N = 87,678). The outcome was whether any household member received SNAP in the previous 12 months. Immigrant policy exposures came from two sources: the State Immigration Policy Resource, which includes 18 immigrant criminalizing and integrating policies, and a database that identified 'sanctuary policies' (SP), which we summarized at the county level. Multivariable logistic regression adjusted for person/household-level and area-level confounders. Results: Living in a jurisdiction with a SP was associated with 21% higher odds of enrolling in SNAP compared to living in a jurisdiction without a SP (adjusted odds ratio [aOR] 1.21, 95% CI=1.11,1.31). Relative to the least immigrant friendly states, living in the most immigrant-friendly states was associated with 16% higher odds of SNAP enrollment (aOR=1.16, 95%CI=1.06-1.28). When SP and state-level immigrant friendly policy environment were cross-classified, SNAP participation was 23% and 26% higher for those living in jurisdictions with one- and both- exposures, respectively, relative to those with neither (aOR 1.23; CI 1.12,1.36; aOR 1.26; CI 1.15,1.37). Conclusions: Many at high risk of food insecurity - including immigrants and citizens in households with immigrants - are eligible for SNAP but under-enroll. Policies that welcome and safeguard immigrants could reduce under enrollment.
