Epidemiological Paradox or Immigrant Vulnerability? Obesity Among Young Children of Immigrants

Application of the Social Cognitive Theory amid food parenting practices of Black immigrant mothers in the US: A qualitative study

BACKGROUND

Children of Black immigrant parents living in the US are at elevated risk of being overweight or obese, thus increasing their risks of morbidity and mortality as they age. Parents play a crucial role in shaping their children's nutrition through their food parenting practices. The Social Cognitive Theory (SCT) can explain Black immigrant mother's FPP and their children's dietary behavior. This study aimed to assess SCT's constructs, personal (maternal knowledge, attitudes, beliefs) and environmental factors (acculturation) in relation to the behavioral factor (food parenting practices) among a sample of Black immigrant mothers living in Metro Atlanta, Georgia.

METHODS

Convenience sampling was employed to recruit 30 Black immigrant mothers who lived in seven Metro Atlanta, Georgia counties in the summer of 2022. Four focus group interviews were conducted over two weeks. The qualitative data analysis was thematic.

RESULTS

Focus group data analysis revealed seven major themes: knowledge, attitude, belief, modeling, acculturation, coercive control, and structure, and six subthemes. Mothers discussed being intentional about encouraging healthy foods and limiting unhealthy foods for their children. Overall, acculturation influenced mothers' food parenting practices. Since migrating to the US, some mothers' nutrition changed in positive (e.g., eating more fruits) and negative ways (e.g., snacking more) because of schedules, cost, and access. Children ate a mixed diet, the mother's native diet and the American diet, and the former was considered healthier and affordable by most.

CONCLUSION

This is the first study to look at the food parenting practices of Black immigrants in the US. By identifying key factors that influence the food parenting practices of this population and their children's dietary habits, this study's findings are useful to practitioners or researchers who work with this population on nutrition.

BMI Growth Profiles Among Black Children from Immigrant and US-Born Families

A large body of research has documented racial/ethnic disparities in childhood obesity in the United States (US) but less work has sought to understand differences within racial groups. Longitudinal studies are needed to describe BMI trajectories across development, particularly for Black children from immigrant families who have been underrepresented in childhood obesity research. The current study utilizes BMI data collected longitudinally from ages 5 to 8 years and growth mixture modeling to (1) identify and visualize growth patterns among Black children from primarily Caribbean immigrant families, and (2) to compare these patterns to growth trajectories among Black children from US-born families. First, we identified four classes or trajectories of growth for Black children from immigrant families. The largest trajectory (70% of the sample) maintained non-overweight throughout the study period. A second trajectory developed overweight by age 8 (25%). Two small trajectory groups demonstrated high rates of moderate and severe obesity-i.e., specifically, a trajectory of accelerated weight gain ending in moderate/severe obesity (3%), and a trajectory of early severe obesity with BMI decreasing slightly with age (2%). We identified a very similar four class/trajectory model among Black children from US-born families, and compared the model to the one for children from immigrant families using multi-group growth mixture modeling. We found that the patterns of growth did not differ significantly between the populations, with two notable exceptions. Among Black children from immigrant families, ∼ 5% were classified into the two heavier BMI trajectories, compared to ∼ 11% of children from US-born families. Additionally, among children with an accelerated weight gain trajectory, children from immigrant families had lower BMIs on average at each time point than children from US-born families. These findings describe the multiple trajectories of weight gain among Black children from immigrant families and demonstrate that although these trajectories are largely similar to those of Black children from US-born families, the differences provide some evidence for lower obesity risk among Black children from immigrant families compared to Black children from US-born families. As this study is the first to describe BMI trajectories for Black children from immigrant families across early and middle childhood, future work is needed to replicate these results and to explore differences in heavier weight trajectories between children from immigrant and US-born families.

Vision Loss in Children from Immigrant and Nonimmigrant Households: Evidence from the National Survey of Children's Health 2018-2020

The aim of this study was to determine whether immigrant generation is associated with caregiver-reported vision loss in children adjusting for sociodemographic characteristics. Nationally representative data from the National Survey of Children's Health (2018-2020) was used. The primary exposure was immigrant generation defined as: first (child and all reported parents were born outside the United States); second (child was born in the United States and at least one parent was born outside the United States); third or higher (all parents in the household were born in the United States). The main outcome was caregiver-reported vision loss in child. Adjusted odds ratios (aOR) and 95% confidence intervals were computed based on immigration generation. The study sample included 84,860 US children aged 3-17 years. First generation children had higher adjusted odds of caregiver-reported vision loss (aOR 2.30; 95% CI 1.21, 4.35) than third or higher generation children after adjusting for demographic characteristics and social determinants of health. For Hispanic families, first generation (aOR 2.99; 95% CI 1.34, 6.66), and second-generation children (aOR 1.70; 95% CI 1.06, 2.74) had a higher adjusted odds of vision loss compared with third or higher generation children. Even when adjusting for sociodemographic characteristics, first generation children had greater odds of vision loss, especially in Hispanic households, than third generation children. Immigration generation should be treated as an independent risk factor for vision loss for children and is a social determinant of eye health.

Neighborhood and Behavioral Effects on Weight Change Across Immigrant Generations: Evidence from the National Longitudinal Study of Adolescent to Adult Health (Add Health)

BACKGROUND

Childhood obesity is a global problem that disproportionately affects minority populations in the USA. Relative to all US-born individuals, some foreign-born populations also experience higher obesity risk. Prior research focuses on the role of healthy behaviors in increasing obesity risk, but the neighborhoods in which individuals reside shape those behaviors. The aim of this study is to examine how changes in health behaviors and neighborhood characteristics affect weight change across immigrant generational groups.

METHODS

The study uses a prospective longitudinal cohort of 3,506 adolescents first interviewed in 1994 (The National Longitudinal Study of Adolescent to Adult Health). To examine the relationship between immigrant generational status and weight change over time while considering healthy behaviors and the neighborhood environment, this research relies on linear multilevel methods.

RESULTS

Neighborhood disadvantage, not health behaviors, has a significant effect on weight change - for both first-generation Asians (β = 1.52; p < 0.001) and Latinxs across all immigrant generations. In neighborhoods where residents do not engage in much exercise, the role that one's level of physical activity plays in weight change is lower than in places where residents engage in much exercise, irrespective of immigrant generation.

CONCLUSION

These findings provide some evidence that neighborhood features and physical activity in the neighborhood may curb obesity risk among adolescents and young adults. The results can inform urban planning efforts and community-based interventions to increase physical activity across ethnic minority populations.

Community Solutions to Increase the Healthfulness of Grocery Stores: Perspectives of Immigrant Parents

Grocery store environments are recognized as one of the most crucial community settings for developing and maintaining healthy nutritional behaviors in children. This is especially true for disadvantaged ethnic minority families, such as immigrants, who reside in the Detroit Metropolitan area and have historically experienced inequities that result in poor health outcomes. Rates of obesity and type II diabetes have affected Detroit 38% more than the rest of the state and nationwide. In 2019, almost 54% of children aged 0-17 in Metro Detroit lived in poverty, and 21.6% experienced food insecurity, compared with the state level of 14.2%. Moreover, nearly 50% of ethnic minority children in Metro Detroit consume sports drinks, and 70% consume soda or pop in an average week. The primary purpose of this study was to explore immigrant parents' perspectives on (1) how in-store Sugar-Sweetened Beverage (SSB) marketing impacts the purchasing behaviors of parents and the eating behaviors of toddlers, and the secondary objective was to (2) determine strategies to reduce SSB purchases and consumption within grocery environments from the viewpoints of immigrant parents. A qualitative multiple-case study design was used to achieve the aims of this study. Semi-structured individual interviews were completed with 18 immigrant parents of children aged 2 to 5 years old who were consumers in 30 independently owned full-service grocery stores within the immigrant enclaves of Detroit, Dearborn, Hamtramck, and Warren, Michigan. Three key thematic categories emerged from the parents' narratives. These themes were: (1) non-supportive grocery store environments; (2) acculturation to the American food environment; and (3) strategies to support reduced SSB consumption among young immigrant children. The findings of this study revealed widespread SSB marketing targeting toddlers within the participating independently owned grocery stores. Even if families with young children practiced healthy nutritional behaviors, the prices, placements, and promotion of SSBs were challenges to establishing and sustaining these healthy eating habits. The parents believed that planning and implementing retail-based strategies in collaboration with families and considering families' actual demands would assist in managing children's eating patterns and reducing early childhood obesity.

Children's longitudinal bodyweight in Australia: Influence of migrant mothers' long-term residency, attachment to, and level of childhood overweight in country-of-birth

Immigration creates opportunities and imposes constraints associated with acculturation. We used the Australian national longitudinal survey of children aged 2 to 17 to evaluate the influence of mothers' long-term residency in Australia, mothers' attachment to country-of-birth, and macro indicators of childhood overweight environment at mothers' country-of-birth on children's longitudinal bodyweight. Both mothers' long-term exposure to the Australian environment and attachment to country-of-birth were associated with increased children's bodyweight z-scores. The childhood overweight environment in mothers' country-of-birth continued to influence their children's bodyweight after immigration. A better understanding of factors related to mothers' migration and children's bodyweight status is necessary to identify risk factors and migrant sub-groups needing extra support.

Contraceptive Consistency and Poverty after Birth

Unplanned pregnancies in the U.S. disproportionately occur among poor, less educated, and minority women, but it is unclear whether poverty following a birth is itself an outcome of this pregnancy planning status. Using the National Longitudinal Survey of Youth 1997 (n=2,101) and National Survey of Family Growth (n=778), we constructed two-year sequences of contraceptive use before a birth that signal an unplanned versus a planned birth. We regressed poverty in the year of the birth both on this contraceptive-sequence variable and on sociodemographic indicators including previous employment and poverty status in the year before the birth, race/ethnicity, education, partnership status, birth order, and family background. Compared to sequences indicating a planned birth, sequences of inconsistent use and non-use of contraception were associated with a higher likelihood of poverty following a birth, both before and after controlling for sociodemographic variables, and before and after additionally controlling for poverty status before the birth. In pooled-survey estimates with all controls included, having not used contraception consistently is associated with a 42% higher odds of poverty after birth. The positive association of poverty after birth with contraceptive inconsistency or non-use, however, is limited to women with low to medium educational attainment. These findings encourage further exploration into relationships between contraceptive access and behavior and subsequent adverse outcomes for the mother and her children.

Prevalence of self-reported obesity among diverse Latino adult populations in New York City, 2013-2017

INTRODUCTION

Latinos in the United States represent a heterogeneous population disproportionally impacted by obesity. Yet, the prevalence of obesity by specific Latino group is unclear. Using the New York City Community Health Survey (2013-2017), this study compared self-reported obesity in the city's largest Latino adult populations (Puerto Ricans, Mexicans, Dominicans, Ecuadorians, and Colombians).

METHODS

Age-standardized prevalence using the 2000 Census and prevalence ratios (PRs) for self-reported obesity (BMI ≥30 kg/m2) by country of origin were estimated using weighted multivariable logistic regression adjusting for socio-demographic characteristics, health status, and behaviors.

RESULTS

Obesity prevalence among Mexicans (36.8%; 95% CI [31.5, 42.4]) and Puerto Ricans (36.3%; 95% CI [31.7, 41.3]) was significantly higher than that among Colombians (23.8%; 95% CI [18.8, 29.5]), Ecuadorians (24.2%; 95% CI [20.7, 28.1]), and Dominicans (27.0%; 95% CI [25.0, 29.1]). After adjusting for covariates, compared to Mexicans, the PRs of obesity remained significantly lower for Colombians (PR = 0.80; 95% CI [0.64, 1.00]), Ecuadorians (PR = 0.72; 95% CI [0.61, 0.86]) and Dominicans (PR = 0.75; 95% CI [0.65, 0.85]). There was no significant difference between Mexicans and Puerto Ricans.

CONCLUSION

Obesity prevalence differs by country of origin, suggesting that clustering of Latinos in public health research may obscure unique risks among specific groups. Despite group differences, all Latino groups exhibit high prevalence of obesity and warrant renewed efforts tailored to the specific context and culture of each group to prevent and reduce obesity.

The Health of Children in Immigrant Families: Key Drivers and Research Gaps Through an Equity Lens

OBJECTIVE

The United States benefits economically and socially from the diverse skill-set and innovative contributions of immigrants. By applying a socioecological framework with an equity lens, we aim to provide an overview of the health of children in immigrant families (CIF) in the United States, identify gaps in related research, and suggest future areas of focus to advance health equity.

METHODS

The literature review consisted of identifying academic and gray literature using a MeSH Database, Clinical Queries, and relevant keywords in 3 electronic databases (PubMed, Web of Science, and BrowZine). Search terms were selected with goals of: 1) conceptualizing a model of key drivers of health for CIF; 2) describing and classifying key drivers of health for CIF; and 3) identifying knowledge gaps.

RESULTS

The initial search produced 1120 results which were screened for relevance using a meta-narrative approach. Of these, 224 papers were selected, categorized by topic, and reviewed in collaboration with the authors. Key topic areas included patient and family outcomes, institutional and community environments, the impact of public policy, and opportunities for research. Key inequities were identified in health outcomes; access to quality health care, housing, education, employment opportunities; immigration policies; and inclusion in and funding for research. Important resiliency factors for CIF included strong family connections and social networks.

CONCLUSIONS

Broad structural inequities contribute to poor health outcomes among immigrant families. While resiliency factors exist, research on the impact of certain important drivers of health, such as structural and cultural racism, is missing regarding this population. More work is needed to inform the development and optimization of programs and policies aimed at improving outcomes for CIF. However, research should incorporate expertise from within immigrant communities. Finally, interventions to improve outcomes for CIF should be considered in the context of the socioecological model which informs the upstream and downstream drivers of health outcomes.

Parental migrant status and health inequalities at birth: The role of immigrant educational selectivity

Immigrants tend to exhibit better health than natives despite immigrants' more disadvantaged socioeconomic status. This paradox has often been attributed to immigrants' pre-migration selectivity. However, most empirical studies investigating the role of selectivity have focused on adult health; less attention has been paid to children's birth outcomes outside the U.S. context. Using data from the Etude Longitudinale Française depuis l'Enfance (ELFE), a nationally representative sample of over 18000 births in France in 2011, we investigate the role of immigrant parents' educational selectivity in shaping four birth outcomes: birthweight, low birthweight, prematurity, and being born small for gestational age. Results from linear and logistic regressions confirm a health advantage for children of immigrants compared to natives despite lower parental socioeconomic status, mainly among children of Middle Eastern and North African parents. Immigrant parents' positive pre-migration educational selectivity explains most of this health advantage, predominantly among children with two immigrant parents. Further, mediation analyses indicate that the effect of educational selectivity is partially mediated by parental health behaviors, particularly smoking during pregnancy. Furthermore, analyses suggest that selectivity improves birth outcomes only for children of recent arrivals, with less than five years of residence in France. The beneficial effect of selectivity declines with length of residence, suggesting that a process of "unhealthy assimilation," coupled with the cumulative exposure to health risks and disadvantaged living conditions, may lead to the erosion of the protective effect of immigrant selectivity.

Perspectives of Caregivers on the Effects of Migration on the Nutrition, Health and Physical Activity of their Young Children: A Qualitative Study with Immigrant and Refugee Families

To explore perspectives on nutrition, health and physical activity among immigrant parents with young children before and after migration. We conducted focus groups in five languages (Arabic, Somali, Dari, Burmese and Nepali), then conducted a phenomenological analysis of the transcripts. Fifty caregivers participated; 42% spent time in a refugee camp. Within the domain Change in Environment, four themes emerged: (1) food access; (2) family experiences with weight and growth; (3) differences in physical activity and perceptions of safety; and (4) health care experience. Within the domain of Parenting Behaviors and Experiences, two themes emerged: (1) Sociocultural differences in early feeding behaviors and (2) concern about feeding behaviors. To support health outcomes for refugee and immigrant families with young children, key focus areas for programming would include access to fresh foods, safe places for physical activity, and feeding practices following a family history of food scarcity.

Potentially avoidable hospitalization for asthma in children and adolescents by migrant status: results from the Italian Network for Longitudinal Metropolitan Studies

Background

Global migration toward Europe is increasing. Providing health assistance to migrants is challenging because numerous barriers limit their accessibility to health services. Migrants may be at a greater risk of developing asthma and receiving lower quality healthcare assistance than non-migrants. We aim to investigate whether immigrants as children and adolescents have higher rates of potentially avoidable hospitalization (PAH) for asthma compared to Italians.

Methods

We performed a retrospective longitudinal study using six cohorts of 2–17-year-old residents in North and Central Italy from 01/01/2001 to 31/12/2014 (N = 1,256,826). We linked asthma hospital discharges to individuals using anonymized keys. We estimated cohort-specific age and calendar-year-adjusted asthma PAH rate ratios (HRRs) and 95% confidence intervals (95%CIs) among immigrants compared to Italians. We applied a two-stage random effect model to estimate asthma PAH meta-analytic rate ratios (MHRRs). We analyzed data by gender and geographical area of origin countries.

Results

Three thousand three hundred four and 471 discharges for asthma PAH occurred among Italians and immigrants, respectively. Compared to Italians, the asthma PAH cohort-specific rate was higher for immigrant males in Bologna (HRR:2.42; 95%CI:1.53–3.81) and Roma (1.22; 1.02–1.45), and for females in Torino (1.56; 1.10–2.20) and Roma (1.82; 1.50–2.20). Asthma PAH MHRRs were higher only among immigrant females (MHRRs:1.48; 95%CI:1.18–1.87). MHRRs by area of origin were 63 to 113% higher among immigrants, except for Central-Eastern Europeans (0.80; 0.65–0.98).

Conclusion

The asthma PAH meta-analytic rate was higher among female children and adolescent immigrants compared to Italians, with heterogeneity among cohorts showing higher cohort-specific PAH also among males, with some differences by origin country. Access to primary care for children and adolescent immigrants should be improved and immigrants should be considered at risk of severe asthma outcomes and consequently targeted by clinicians.

Silesians in Texas and Upper Silesia: anthropometric, functional and physical activity characteristics

Anthropometric, functional and physical activity characteristics of contemporary adult descendants of Upper Silesian immigrants to Texas in the mid-19th century and current residents in Upper Silesia were compared. The sample included 45 residents in Central Texas, 25 women and 20 men, and 36 residents in rural Upper Silesia, 24 women and 12 men, 54-76 years of age. Variables included selected demographic characteristics, anthropometry, estimated body composition, several physiological indicators, strength and functional fitness, and physical activity. Sex-specific MANCOVA and Chi square were used for comparisons. Descendants of Silesian immigrants to Texas were taller, on average, while differences in other anthropometric variables were variable. All residents in Silesia and the majority of descendants of Silesian migrants to Texas were overweight or obese. Differences in hemodynamic and respiratory functions and responses to a 6-minute walk were inconsistent, while none of the fitness variables differed significantly between the samples. Although residents in Upper Silesia were significantly more physically active descendants of Silesians in Texas, >80% of the men and women in both samples scored below the criterion-reference standard for the maintenance of physical independence in the 6-minute walk.

Individual-, family-, and contextual-level variables do not explain the protective effect of parental nativity status on changes in 3-15-year-old children's BMI

Individual-, family-, and contextual-level factors can simultaneously and interactively affect a child's body mass index (BMI). We examine parental nativity as a key determinant of changes in children's BMI over time. Prior research on this topic has been inconclusive. A longitudinal sample of households with children residing in four low-income, high minority New Jersey cities provided data on demographics, socioeconomic status, anthropometric measures, as well as dietary and physical activity behaviors for one randomly selected child. The baseline interview for two separate cohorts took place in 2009/10 and 2014-15, with a follow-up interview 2–5 years later. The outcome variable, change in BMI z-score was divided into three categories (decrease in BMI z-score; no meaningful change; increase in BMI z-score) and analyzed using ordinal logistic regressions. About 28% of the children in the sample had at least one foreign-born parent. For the two major racial/ethnic groups, i.e., Hispanics and non-Hispanic blacks, having a foreign-born parent was associated with a favorable change in BMI—children of foreign-born parents were more likely to experience a decrease BMI z-score between baseline and follow-up. Multivariate analyses reveal that the initial association between parental nativity and children's BMI change (OR = 0.20; p < 0.001) persists after controlling for an extensive set of covariates, such as child dietary and physical activity behaviors, family-level variables, census tract characteristics, and measures of food environment (OR = 0.17; p < 0.001). Through a series of sensitivity analyses, we verified that our results are consistent across different model specifications. In our sample, having a foreign-born parent was a protective factor for children's BMI change that operates through different pathways than might be anticipated.

Food Insecurity and Major Diet-Related Morbidities in Migrating Children: A Systematic Review

Children of migrant families are known to be at a higher risk of diet-related morbidities due to complex variables including food insecurity, cultural and religious beliefs, and sociodemographic factors like ethnicity, socioeconomic status, and education. Several studies have assessed the presence of specific diseases related to dietary issues in migrant children. This systematic review aims to highlight the existing body of work on nutritional deficiencies in the specific vulnerable pediatric population of immigrants. Refugees were intentionally excluded because of fundamental differences between the two groups including the reasons for migration and health status at the time of arrival. A total of 29 papers were included and assessed for quality. Most of them described a strong correlation between obesity and migration. A high prevalence of stunting, early childhood caries, iron and vitamin D deficiency was also reported, but the studies were few and heterogeneous. Food insecurity and acculturation were found important social factors (nevertheless with inconclusive results) influencing dietary habits and contributing to the development of morbidities such as obesity and other metabolic disorders, which can cause progressive unsustainability of health systems. Public health screening for diet-related diseases in migrant children may be implemented. Educational programs to improve children’s diet and promote healthy-living behaviors as a form of socioeconomic investment for the health of the new generations may also be considered.

Parent activation and pediatric primary care outcomes for vulnerable children: A mixed methods study

OBJECTIVE

Among children in low-income families 1) examine associations between parent activation and pediatric primary care outcomes and 2) explore parent perspectives on Parent-Patient Activation Measure (P-PAM) questions in relation to pediatric primary care experiences.

METHODS

We examined associations between P-PAM score via Spanish- or English-language survey and healthcare outcomes abstracted from electronic medical records for parent/child dyads at an urban general pediatrics clinic. Parent perspectives were elicited via qualitative interviews with a subsample of parents who "thought aloud" during P-PAM completion.

RESULTS

Among 316 Spanish (68%) and English-language parent/child dyads, we found associations between parent activation and primary care outcomes only among Spanish-language dyads and only for weight and health status. Findings from 21 interviews provided possible explanations for quantitative findings including question limitations in assessing knowledge, skills, and confidence in pediatric primary care and P-PAM cultural and linguistic appropriateness for low-income Latino populations.

CONCLUSIONS

Pairing quantitative and qualitative methods provided insight on P-PAM measurement limitations and raised questions about its use in patient engagement interventions to reduce health disparities.

PRACTICE IMPLICATIONS

Practices serving vulnerable children and families should consider the limitations of the P-PAM for measuring parent healthcare engagement before utilizing the P-PAM in patient engagement interventions.

Mind the gap: The health advantages that accompany parental marriage vary by maternal nativity

Using data from the UK Millennium Cohort Study (MCS), we examine whether and how the health benefits of having two biological parents in a continuous marital relationship vary by maternal nativity and ethnicity, comparing UK-born White mothers with: (1) White mothers born in wealthy countries; (2) ethnic minority mothers from South Asia; and (3) ethnic minority mothers born in Africa. Making novel use of classification and regression tree (CART) methods, we examine whether marital status is a uniform marker of economic advantage or better health-related behaviours across the four maternal nativity and ethnic groups. The findings, which indicate that the health-related advantages associated with parental marriage are not uniform across the four nativity and ethnic groups, have implications for future research on family gaps in well-being and the socio-economic determinants of health.

Associations between breastfeeding duration and overweight/obese among children aged 5-10: a focus on racial/ethnic disparities in California

Research on the association between breastfeeding and childhood obesity and research on racial/ethnic differences in breastfeeding both show inconsistencies. The current study examines: 1) whether immigrant Hispanic women have higher rates of breastfeeding compared to non-Hispanic (three separate groups: African-American, Asian/Pacific Islander, and White) and U.S.-born Hispanic women; 2) whether children who were breastfed are less likely to be overweight/obese compared to children who were not breastfed; and 3) whether associations between breastfeeding and weight status vary by race/ethnicity/nativity. The study builds on prior literature using representative data from the Geographic Research On Wellbeing study (GROW, 2012-2013) and focusing on ages 5-10 years, an age group that has not been well studied (N = 2675 mother/child dyads). Logistic regression was used to investigate the odds of child obesity (≥95th%) and child overweight (≥85th%) in a series of models: unadjusted (each variable individually), demographic (child's sex, child's age, mother's age, mother's race/ethnicity, and mother's marital status), socioeconomic status (mother's education and family income), and full model (mother's BMI); with breastfeeding included in all models. Interactions between race/ethnicity and breastfeeding duration were also examined. African-American (9.54%) and white (32.8%) women had the lowest and highest rates of ever breastfeeding, respectively. White women breastfed the longest (M = 10.52 months, SE = 0.028) and U.S.-born Hispanic women breastfed the shortest (M = 7.05 months, SE = 0.41), on average. Children of African-American and U.S.-born Hispanic mothers had higher odds of being overweight/obese (74-75%) compared with children of white mothers. No associations were found between breastfeeding duration and child's weight status in adjusted models, nor was there a significant interaction between mother's race/ethnicity and breastfeeding duration on child's weight status; however, mother's own weight status was a significant driver of child's weight status and explained the racial/ethnic disparities. These results provide evidence in favor of there being no association between breastfeeding and childhood obesity.

Inflammation among Children: Evidence of an Immigrant Advantage?

Past research on the immigrant health paradox suggests that children with immigrant parents may have a health advantage over those with U.S.-born parents, especially if the parent is a recent immigrant. Other research emphasizes the social and economic challenges children with immigrant parents face, in part due to disadvantaged social class and racial/ethnic positions. Underlying physiological changes due to chronic stress exposures among children in immigrant families is one potential health disadvantage that may not yet be apparent in traditional health measures. To explore these biological disparities during childhood, I use national biomarker and survey data from NHANES (N=11,866) to evaluate parent nativity and educational status associations with low-grade inflammation, indicated by C-reactive Protein (CRP), in children ages 2-15 years. I find that children with an immigrant parent, and particularly a low-education immigrant parent, have higher CRP, net of birth, BMI and other factors, than children with a U.S. born parent with either a low or higher education. Comparing children with low-educated parents, those with a foreign-born parent have higher predicted CRP. The findings from this study provide new evidence that children living in immigrant families in the U.S. may be facing higher levels of chronic stress exposure, as indicated by the increased risk of low-grade inflammation, than those with U.S.-born parents. The physiological changes related to increased risk of inflammation could set children in immigrant families on pathways towards mental and physical health problems throughout childhood and later in the life course.

Child, Caregiver, Family, and Social-Contextual Factors to Consider when Implementing Parent-Focused Child Feeding Interventions

PURPOSE OF REVIEW

Interventions that aim to alter child eating behaviors often focus on parents as a proximal influence. Yet, parents can be difficult to engage. Therefore, intervention recommendations are often not implemented as designed. The goal of this review is to highlight factors at multiple contextual levels that are important to consider when developing interventions to address child eating, due to their implications for overcoming parent engagement challenges.

RECENT FINDINGS

Intervention studies suggest that parents are often the key to successfully changing child eating behaviors, and many interventions focus on feeding. Factors such as child eating phenotypes, parent stress, family system dynamics, and sociodemographic constraints have also been identified as shaping food parenting. Challenges at multiple contextual levels can affect the likelihood of parent engagement. Addressing factors at the child-, parent-, family-, and broader social-contextual levels of influence is essential in order to promote best practices for parent-focused feeding interventions.

Racial-ethnic Disparities in Inflammation: Evidence of Weathering in Childhood?

Building on the weathering hypothesis, we advance health disparities research by assessing racial-ethnic differences in low-grade inflammation, a marker of chronic stress exposure, in young children. Using nationally representative data from the National Health and Nutrition Examination Survey (N = 6,652) and logistic regression, we find an increased risk of low-grade inflammation among Hispanic and African American children compared to white children. The risk of inflammation appears to be stronger for Hispanic and African American children with foreign-born parents compared to children of the same race-ethnicity with U.S.-born parents. Low parental education and elevated child body mass index work as partial mediators of these associations. Our findings suggest the need to understand the psychosocial challenges faced by Hispanic and African American children, particularly, those with foreign-born parents, if we are to make further progress in reducing health disparities.

Growing up in Australia: paradox of overweight/obesity in children of immigrants from low-and-middle -income countries

Objective

Children of immigrants from low-and-middle-income countries show excess overweight/obesity risk relative to host populations, possibly due to socioeconomic disadvantage. The present study was conducted to estimate overweight/obesity prevalence and its association with the family socioeconomic-position in 2-11-year-old Australian-born children of immigrants and Australian-mothers.

Methods

A cross-sectional analysis of 10-year data from the Longitudinal Study of Australian Children was undertaken. Overweight/obesity was defined according to the International Obesity Taskforce, age-and sex-specific BMI cut-off-points.

Results

Approximately 24% children aged 2-3 years (22% sons, and 25% daughters), were overweight/obese with no significant difference between children of immigrants and Australian-mothers. Overweight/obesity prevalence consistently increased with age for sons of mothers from low-and-middle-income countries but not daughters. Adjusting for the family socioeconomic-position did not explain excess overweight/obesity in children of mothers from low-and-middle-income countries. The odds of overweight/obesity in sons were significantly higher at 8-9 years (OR 1.5; p = 0.03) and 10-11 years (OR 1.5; p = 0.03) and in daughters at 4-5 years (OR 1.7; p = 0.002) when the mothers were from low-and-middle-income countries.

Conclusion

Excess weight in children of immigrants is not due to socioeconomic disadvantage alone. Other social processes and interactions between immigrants and host cultures may be involved.

One Size May Not Fit All: How Obesity Among Mexican-Origin Youth Varies by Generation, Gender, and Age

Immigrants' health (dis)advantages are increasingly recognized as not being uniform, leading to calls for studies investigating whether immigrant health outcomes are dependent on factors that exacerbate health risks. We answer this call, considering an outcome with competing evidence about immigrants' vulnerability versus risk: childhood obesity. More specifically, we investigate obesity among three generations of Mexican-origin youth relative to one another and to U.S.-born whites. We posit that risk is dependent on the intersection of generational status, gender, and age, which all influence exposure to U.S. society and weight concerns. Analyses of National Health and Nutrition Examination Studies (NHANES) data suggest that accounting for ethnicity and generation alone misses considerable gender and age heterogeneity in childhood obesity among Mexican-origin and white youth. For example, second-generation boys are vulnerable to obesity, but the odds of obesity for first-generation girls are low and on par with those of white girls. Findings also indicate that age moderates ethnic/generational differences in obesity among boys but not among girls. Overall, ethnic/generational patterns of childhood obesity do not conform to a "one size fits all" theory of immigrant health (dis)advantage, leading us to join calls for more research considering how immigrants' characteristics and contexts differentially shape vulnerability to disease and death.

Infant feeding patterns and eczema in children in the first 6 years of life

BACKGROUND

Modes of infant feeding such as direct and indirect breastfeeding, and formula feeding, and their combinations may play a role in child health.

OBJECTIVE

The aim was to investigate which feeding patterns in the first 6 months pose risks of eczema/skin allergy in children up to 6 years compared to direct breastfeeding for at least 3 months.

METHODS

The Infant Feeding Practices Study II in the United States and its 6-year follow-up provided data on feeding modes in infancy and doctor's diagnosed eczema/skin allergy in the first 6 years of life (1387 infants), based on parental reports. Different feeding patterns were identified. Log-linear models were used to estimate prevalence ratios (PRs) of feeding patterns for doctor's diagnosed eczema/skin allergy in the first 6 years of life, adjusting for confounders.

RESULTS

Compared to "direct breastfeeding for at least 3 months" (DBF3m), the combination of "direct feeding at the breast (DBF), pumping and feeding breast milk (BM), and formula (FF) in the first months" (DBF/BM/FF) showed a statistically significant higher risk of eczema/skin allergy in the first 6 years of life (PR = 1.46), adjusting for confounders. DBF combined with BM for the first 3 months followed by mixed feeding also had an increased risk (PR = 1.26), although not statistically significant. Formula feeding introduced since birth had no effect on eczema. Among the confounders, paternal eczema and race/ethnicity (Hispanic vs White) were associated with a higher risk of eczema/skin allergy.

CONCLUSIONS & CLINICAL RELEVANCE

Mixed infant feeding may carry a higher risk of eczema/skin allergy compared to direct feeding at the breast. The recent epidemic of pumping and feeding in the United States and the use of mixed infant feeding modes requires additional studies to provide appropriate and renewed assessments of the risks of feeding modes for the future development of allergies.

Intergenerational persistence of health: Do immigrants get healthier as they remain in the U.S. for more generations?

It is well known that a substantial part of income and education is passed on from parents to children, generating substantial persistence in socioeconomic status across generations. In this paper, we examine whether another form of human capital, health, is also largely transmitted from generation to generation. Using data from the NLSY, we first present new evidence on intergenerational transmission of health outcomes in the U.S., including weight, height, the body mass index (BMI), asthma and depression for both natives and immigrants. We show that between 50% and 70% of the mothers' health status persists in both native and immigrant children, and that, on average, immigrants experience higher persistence than natives in BMI. We also find that the longer immigrants remain in the U.S., the less intergenerational persistence there is and the more immigrants look like native children. Unfortunately, the more generations immigrant families remain in the U.S., the more children of immigrants resemble natives' higher BMI.

Becoming American, becoming obese? A systematic review of acculturation and weight among Latino youth

Latino youth have the highest rate of overweight and obesity across ethnic and racial groups, placing these individuals at increased risk for a variety of negative immediate and long-term health outcomes. Many studies have shown that acculturative factors play a role in this process for adults, while less is known about the impact of these factors for children and adolescents. This study systematically reviews the current literature on acculturative factors and obesity among Latino children. Three hundred and seventy-nine studies were independently reviewed by two coders for eligibility. Twenty-nine studies met eligibility criteria and were included in the final review. Results indicated that relations between acculturation and obesity among Latino children are equivocal. Across studies reviewed, the significance and directionality of this relation differed. Heterogeneity across studies reviewed, including age, specific population and measures used for assessing acculturation, likely contributed to the mixed results. To provide greater clarity on the role of acculturative factors on obesity, future studies should (i) utilize a longitudinal design; (ii) control for potential confounding factors such as socioeconomic status; and (iii) examine potential moderating and mediating influences.

Epidemiological Paradox or Immigrant Vulnerability? Obesity Among Young Children of Immigrants

According to the "immigrant epidemiological paradox," immigrants and their children enjoy health advantages over their U.S.-born peers--advantages that diminish with greater acculturation. We investigated child obesity as a potentially significant deviation from this paradox for second-generation immigrant children. We evaluated two alternate measures of mother's acculturation: age at arrival in the United States and English language proficiency. To obtain sufficient numbers of second-generation immigrant children, we pooled samples across two related, nationally representative surveys. Each included measured (not parent-reported) height and weight of kindergartners. We also estimated models that alternately included and excluded mother's pre-pregnancy weight status as a predictor. Our findings are opposite to those predicted by the immigrant epidemiological paradox: children of U.S.-born mothers were less likely to be obese than otherwise similar children of foreign-born mothers; and the children of the least-acculturated immigrant mothers, as measured by low English language proficiency, were the most likely to be obese. Foreign-born mothers had lower (healthier) pre-pregnancy weight than U.S.-born mothers, and this was protective against their second-generation children's obesity. This protection, however, was not sufficiently strong to outweigh factors associated or correlated with the mothers' linguistic isolation and marginal status as immigrants.
