Ethnicity and acculturation: do they predict weight status in a longitudinal study among Asian, Hispanic, and non-Hispanic White early adolescent females?

Social network body size is associated with body size norms of South Asian adults

Aims

To examine the association between social network body size and body size norms in South Asian adults.

Methods

Participants (n = 766) from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study (2014-2018) provided detailed information about their five closest network members. Participants' perceptions of their network members' body sizes, their own body size (self-body size), and a healthy body size for men and women (body size norms) were assessed using the Stunkard 9-figure scale. Adjusted hierarchical linear regression models were used to examine associations between the average body size of network members and perceived body size norms.

Results

Participants' average age was 59.1 years (SD = 9.2) and 44.1% were women. Participants reported an average network body size of 4.0 (SD = 1.1). The average body size norm for male and female Stunkard images was 3.6 (SD = 1.0) and 3.4 (SD = 0.8), respectively. Social network body size was positively associated with increasing body size norms (β-coefficient = 0.31, 95% CI: 0.26, 0.36), independent of self-body size.

Discussion

Social networks may influence body size norms in South Asian adults. Long-term follow up of the MASALA cohort will determine if social network body size and body size norms are associated with weight- control behaviors and weight change.

Association between acculturation and body weight status among migrant children in Guangzhou, China: a cross-sectional study

OBJECTIVE

To assess the association between acculturation and body weight status among internal migrant children in China.

DESIGN, SETTING AND PARTICIPANTS

A cross-sectional study was conducted among 1154 pairs of migrant children aged 11-17 years and their primary caregivers in Guangzhou, China, from April to May 2016.

MEASURES

Migrant children's body weight status was measured by body mass index. Acculturation was measured by a questionnaire, developed and validated by the research team. The questionnaire had three dimensions with five factors, namely language, social interaction, custom, dressing and diet. Social anxiety was measured by Social Anxiety Scale for Children. Food intake was measured by the food frequency table that was developed from a previous study. Logistic regression was performed to examine the association between acculturation and overweight/obesity while controlling for migrant children's and their caregivers' demographic characteristics, children's social anxiety and food intake.

RESULTS

Seventy-six out of 1154 (6.6%) migrant children were overweight, and 36 (3.1%) were obese. The overall prevalence of overweight/obesity was 12.5% in boys, and 6.1% in girls (p<0.001), respectively. The mean scores of acculturation were 41.8 (SD=14.6). Migrant children had the highest level of acculturation in the aspect of dressing (mean=61.7, SD=16.6), followed by language (mean=47.9, SD=22.3), diet (mean=45.0, SD=18.5), social interaction (mean=42.4, SD=21.3) and custom (mean=27.6, SD=19.2). After controlling for confounding factors, the levels of acculturation was negatively associated with overweight/obesity (adjusted OR (aOR)=0.98, 95% CI 0.97 to 1.00, p=0.030). Furthermore, migrant children who had urban-to-urban migrant caregivers were more likely to be overweight/obese (aOR=2.07, 95% CI 1.16 to 3.69, p=0.014) than their counterparts living with rural-to-urban migrant caregivers.

CONCLUSIONS

The low levels of acculturation was associated with overweight/obesity among migrant children in Guangzhou, China. Promoting healthy acculturation and social campaign on healthy body weight may help prevent childhood overweight/obesity. Young migrant children, boys and children living with urban-to-urban migrant caregivers should be the target subgroups.

Identification and Characterization of Families That Are Positively Deviant for Childhood Obesity in a Latino Population: A Case-Control Study

BACKGROUND

Childhood obesity is a complex public health challenge that requires innovative, sustainable solutions. Positive deviance, inspired by the science of complexity, is an approach that examines what allows certain individuals to succeed despite being predicted to fail. This study is aimed at identifying and defining positive deviants for early childhood obesity.

METHODS

This case-control study used medical record data to identify Latino children aged 2-5 and classify them using their longitudinal weight change. Parents of children with trajectories toward a healthy weight from an obese weight (cases) and parents of children with stable obese weight trajectories over time (controls) were recruited. Mixed-methods analyses were used including a semistructured interview and quantitative surveys evaluating diet, physical activity, sleep, feeding practices, and self-efficacy. Qualitative description was applied to the qualitative data; quantitative data were analyzed using descriptive statistics and logistic regression modeling.

RESULTS

Of eligible Latino children identified from the overall data set (n=1,621), 257 (16%) had trajectories toward a healthy weight, and among these, 21 positively deviant cases completed the study with 23 matched controls. Positive deviant families were characterized by lower education, higher self-efficacy, and a more Mexican cultural orientation. Findings suggest that effective engagement of other caregivers and creating healthy food environments were important determinants of healthy weight outcomes.

CONCLUSIONS

Positive deviants (cases) were distinct from controls in several parenting strategies such as creating healthy food environments and engaging caregivers. They had higher self-efficacy despite lower education. There were fewer differences in diet and physical activity than expected.

Psychosocial aspects of type 1 diabetes in Latino- and Asian-American youth

Latino and Asian-Americans represent the fastest growing immigrant populations in the United States. We aimed to review the current knowledge on the psychosocial factors that influence type 1 diabetes (T1D) care, education, and outcomes in Latino and Asian-American youth immigrants in the United States, as well as culturally sensitive programs to address health disparities. We conducted a narrative, conceptual review of studies on T1D in Latino and Asian-American youth and relevant studies in type 2 diabetes and adults. Approximately 50% of both Latino and Asian-American youth with T1D are in suboptimal glycemic control. Socioeconomic status, literacy, English proficiency, acculturation, access to health care, family functioning, mental health, and nutrition influence T1D care and outcomes. However, the degree to which these complex, inter-related and dynamic factors affect long-term T1D outcomes is largely unknown. Culturally sensitive programs for Latino or Asian-American youth with T1D are scarce in the United States. Research is needed among Latino and Asian-American youth with T1D so that comprehensive, culturally sensitive diabetes education, and care programs can be developed to decrease disparities in the health burden of these groups.

The Impact of Acculturation Level on Weight Status and Weight Outcomes in Hispanic Children

BACKGROUND

Previous studies revealed that higher levels of acculturation are related to obesity in Hispanic adults. Conflicting findings exist regarding this relationship in children, and little is known about the impact of acculturation on children's success in pediatric weight management programs. The purposes of the study were to (1) examine the relationship between acculturation and overweight/obese weight status and (2) determine the impact of acculturation on the changes in weight status among overweight/obese children 12 and 24 months after having participated in a weight management intervention.

METHODS

This is a secondary analysis of aggregated data from three randomized control trials that occurred between 2005 and 2009. Height, weight, and level of acculturation using the Child Short Scale for Hispanics (C-SASH) were measured in a sample of Hispanic children (n = 559). Logistic regression models were used to study phase 1 (n = 559) and phase 2 (n = 142), controlling for child and family characteristics.

RESULTS

Children reporting high levels of acculturation had a 52 % lower odds of being overweight or obese. Among overweight/obese children who participated in the intervention, high levels of acculturation demonstrated greater reductions in standardized body mass index (zBMI) at 24 months.

CONCLUSIONS

The results of this study indicate a need to tailor weight management programs for Hispanic children who have lower levels of acculturation.
