Physical activity participation by parental language use in 4th, 8th, and 11th grade students in Texas, USA

Greater Acculturation is Associated With Poorer Cardiovascular Health in the Multi-Ethnic Study of Atherosclerosis

Background Greater acculturation is associated with increased risk of cardiovascular disease. However, little is known about the association between acculturation and ideal cardiovascular health (CVH) as measured by the American Heart Association's 7 CVH metrics. We investigated the association between acculturation and ideal CVH among a multi-ethnic cohort of US adults free of clinical cardiovascular disease at baseline. Methods and Results This was a cross-sectional analysis of 6506 men and women aged 45 to 84 years of 4 races/ethnicities. We examined measures of acculturation(birthplace, language spoken at home, and years lived in the United States [foreign-born participants]) by CVH score. Scores of 0 to 8 indicate inadequate, 9 to 10 average and 11 to 14 optimal CVH. We used multivariable regression to examine associations between acculturation and CVH, adjusting for age, sex, race/ethnicity, education, income and health insurance. The mean (SD) age was 62 (10) years, 53% were women, 39% non-Hispanic White-, 26% non-Hispanic Black-, 12% Chinese- and 22% Hispanic-Americans. US-born participants had lower odds of optimal CVH (odds ratio [OR]: 0.63 [0.50-0.79], P<0.001) compared with foreign-born participants. Participants who spoke Chinese and other foreign languages at home had greater odds of optimal CVH compared with those who spoke English (1.91 [1.08-3.36], P=0.03; and 1.65 [1.04-2.63], P=0.03, respectively). Foreign-born participants who lived the longest in the United States had lower odds of optimal CVH (0.62 [0.43-0.91], P=0.02). Conclusions Greater US acculturation was associated with poorer CVH. This finding suggests that the promotion of ideal CVH should be encouraged among immigrant populations since more years lived in the United States was associated with poorer CVH.

The Role of the Neighborhood Social Environment in Physical Activity among Hispanic Children: Moderation by Cultural Factors and Mediation by Neighborhood Norms

Little is known about how the neighborhood social environment (e.g., safety, crime, traffic) impacts child physical activity. We examine the mechanism by which the neighborhood social environment is associated with child physical activity, moderated by individual-level cultural factors (e.g., language at home, immigrant generation) and mediated by neighborhood physical activity-related social norms (e.g., seeing walkers in the neighborhood). Data included 2749 non-Hispanic White and Hispanic children from the Healthy Communities Study. Multilevel regression was performed. The neighborhood social environment was not associated with physical activity in the full sample. However, Hispanic children speaking both English and Spanish and first- or second-generation Hispanic children engaged in more physical activity when the quality of the neighborhood social environment was higher (b = 1.60, p < 0.001 for Hispanic children speaking English and Spanish; b = 2.03, p < 0.01 for first-generation Hispanic children; b = 1.29, p < 0.01 for second-generation Hispanic children). Neighborhood physical activity-related social norms mediated the association between the neighborhood social environment and physical activity among Hispanic children speaking English and Spanish (b = 0.33, p < 0.001) and second-generation Hispanic children (b = 0.40, p < 0.001). Findings suggest heterogeneity in how neighborhood social environments impact physical activity by cultural factors. Health promotion programs may need to enhance neighborhood social environments to increase Hispanic children’s physical activity.

Are Correlates of Physical Activity in Adolescents Similar Across Ethnicity/Race and Sex: Implications for Interventions

BACKGROUND

This study tested for differences in personal, social, and environmental correlates of moderate to vigorous physical activity (MVPA) across ethnicity/race in male and female adolescents.

METHODS

Self-reported MVPA and 47 potential correlates of MVPA were measured in an ethnically/racially diverse cross-sectional sample of adolescents, in Minnesota, who participated in EAT-2010 (Eating and Activity in Teens). Interactions of potential correlates with ethnicity/race on MVPA were tested in linear hierarchical regression models in boys and girls.

RESULTS

Boys reported 1.7 more weekly hours of MVPA than girls. White adolescents reported 1.1 to 2.1 more weekly hours of MVPA than nonwhite adolescents. Among girls, neighborhood road connectivity was negatively correlated with MVPA among Hispanic and Asian participants. Among boys, sports participation was positively correlated with MVPA among all ethnicities/races, except Asians. Home media equipment was positively correlated with MVPA among Hispanic boys, but negatively correlated among white boys.

CONCLUSIONS

A few correlates of physical activity among adolescents differed intersectionally by ethnicity/race and sex. Sports participation and home media equipment may have differing impacts on physical activity across ethnicities and races in boys, whereas neighborhood features like road connectivity may have differing impacts on physical activity across ethnicities and races in girls.

Racial/ethnic disparities in health-related quality of life and health status across pre-, early-, and mid-adolescence: a prospective cohort study

PURPOSE

To examine (1) racial/ethnic disparities in health-related quality of life (HRQOL) and overall health status among Black, Latino, and White youth during adolescence; (2) whether socioeconomic status (SES) and family contextual variables influence disparities; and (3) whether disparities are consistent from pre- to early- to mid-adolescence.

METHODS

A population sample of 4823 Black (1755), Latino (1812), and White (1256) youth in three US metropolitan areas was prospectively assessed in a longitudinal survey conducted on three occasions, in 5th, 7th, and 10th grades, when youth reported their HRQOL using the PedsQL™ short-form Total, Physical and Psychosocial scales and youth and parents separately reported on youth's overall health status. Parents reported their education and household income to index SES, family structure, and use of English at home.

RESULTS

Based on analysis conducted separately at each grade, marked racial/ethnic disparities were observed across all measures of HRQOL and health status, favoring White and disfavoring Black, and especially Latino youth. More strongly present in 5th and 7th grade, HRQOL disparities decreased by 10th grade. Most disparities between White and Black youth disappeared when adjusting for SES. However, even after adjusting for SES, family structure, and English use, overall health status disparities disfavoring Latino youth remained across all three assessments.

CONCLUSIONS

Racial/ethnic disparities in adolescent HRQOL and health are substantial. These disparities appear consistent from pre- to early-adolescence but diminish for HRQOL by mid-adolescence. As disparities appear influenced by SES and other family contextual variables differently in different racial/ethnic groups, efforts to reduce health disparities in youth should address culturally specific conditions impinging on health.

Racial and Linguistic Status Differences in the Effect of Interscholastic Sport Participation on School Engagement and Academic Performance Among High School Students

The purpose of the study was to examine whether the effects of interscholastic sport participation on academic performance and school engagement vary by race and linguistic status of high school students. High school participants ( n = 16,200) were selected from the Education Longitudinal Study: 2002, a nationally representative database. Results of a structural equation model showed that Asian, black, and Hispanic students’ interscholastic sport participation had a positive effect on grade point average, while the effect was not significant for white students. However, white students’ interscholastic sport participation was likely to have a positive, indirect effect on grade point average through their engagement in school. The results showed no linguistic status variation in the effects of interscholastic sport participation on school engagement and grade point average. The findings suggest that supporting high school students in school-sponsored extracurricular sport programs should be continued, highlighting the important role of schools in shaping the proper educational environment for sport participation.

Social and Environmental Determinants of Child Physical Activity in a Rural Mexican-Origin Community

California's rural agricultural communities face an increased burden of obesity and metabolic disease. The present objective is to define the social and environmental influences to child obesity and physical activity within Mexican-origin communities in California's Central Valley. A range of data (anthropometric, socioeconomic, demographic, cultural and environmental) were collected on more than 650 children enrolled in Niños Sanos, Familia Sana. Physical activity data were gathered from a subsample of children 4-7 years of age (n = 148) via accelerometer. Cross sectional analyses explored the relationship between BMI and physical activity and the influence of numerous social and environmental variables. In this sample 45 % of children were determined to be overweight or obese. Boys had a higher daily average moderate-to-vigorous physical activity than girls (p = 0.008). Chi square analyses showed weight status was associated with activity level in girls (p = 0.03) but not boys. Multivariate regression revealed several social and environmental indicators influenced BMI and physical activity (p = 0.004). In this population of school-age children of Mexican-origin, girls may benefit more from targeted efforts to increase MVPA. Family and community support systems may also boost child participation in physical activities.

Socioeconomic inequalities in children's diet: the role of the home food environment

Background

It is well documented in the literature that low socioeconomic status (SES) is associated with lower consumption of healthy foods and that these differences in consumption patterns are influenced by neighborhood food environments. Less understood is the role that SES differences in physical and social aspects of the home food environment play in consumption patterns.

Methods

Using data on 4^th grade children from the 2009–2011 Texas School Physical Activity and Nutrition (SPAN) study, we used mixed-effects regression models to test the magnitude of differences in the SPAN Health Eating Index (SHEI) by parental education as an indicator of SES, and the extent to which adjusting for measures of the home food environment, and measures of the neighborhood environment accounted for these SES differences.

Results

Small but significant differences in children’s SHEI by SES strata exist (-1.33 between highest and lowest SES categories, p<0.01). However, incorporating home food environment and neighborhood environment measures in this model eliminates these differences (-0.7, p=0.145). Home food environment explains a greater portion of the difference. Both social (mealtime structure) and physical aspects (food availability) of the home food environment are strongly associated with consumption of healthy and unhealthy foods.

Conclusions

Our findings suggest that modifiable parent behaviors at home can improve children’s eating habits and that the neighborhood may impact diet in ways other than through access to healthy food.

Out-of-school time activity participation among US--immigrant youth

BACKGROUND

Structured out-of-school time (OST) activities are associated with positive academic and psychosocial outcomes.

METHODS

Data came from the 2007 National Survey of Children's Health, restricted to 36,132 youth aged 12-17 years. Logistic regression models were used to examine the joint effects of race/ethnicity and immigrant family type on the participation in OST activities.

RESULTS

Compared with US-born (USB) non-Hispanic White youth with USB parents, USB Hispanic youth with USB parents were less likely to participate in sports, whereas non-Hispanic Black youth with immigrant parents were more likely to participate in sports. White youth with at least 1 immigrant parent had higher odds of participating in after-school clubs. All Hispanic youth were less likely to participate in after-school clubs. USB Hispanic youth, USB Black youth, and White youth and "other" youth with at least 1 immigrant parent had higher odds of engaging in community services. Youth from immigrant families had lower odds of doing paid work.

CONCLUSIONS

Hispanic youth were less likely to participate in OST activities. Non-Hispanic youth with immigrant parents did not engage in fewer OST activities compared with USB White youth with USB parents. Intervention and recruitment strategies for OST activities may need to be customized for immigrant groups.

Racial and ethnic differences in the home food environment explain disparities in dietary practices of middle school children in Texas

OBJECTIVE

To examine racial and ethnic differences among middle school children in the home food environment (HFE) and the extent to which associations of healthy and unhealthy eating with the HFE differ by race and ethnicity.

DESIGN

Cross-sectional secondary analyses of baseline data from Coordinated Approach to Child Health Middle School, a school-based intervention targeting obesity and obesogenic behaviors among middle school children in Austin, TX.

PARTICIPANTS

A total of 2,502 children (mean age, 13.9 years; 58% Hispanic, 28% white, and 14% black).

VARIABLES MEASURED

Availability and accessibility of healthy foods, and parental support of healthy eating, and family meals. Consumption of both healthy and unhealthy foods was examined.

ANALYSIS

Differences across racial and ethnic groups in aspects of HFE were estimated using linear regression. Models also examined racial and ethnic differences in consumption of healthy and unhealthy foods. If adjusting for HFE, such differences were accounted for.

RESULTS

White children had significantly better HFEs than Hispanic and black children with greater availability and accessibility of healthy foods (P < .001). Adjusting for a healthy HFE reduced disparities in consumption of healthy foods but not in consumption of unhealthy foods.

CONCLUSIONS AND IMPLICATIONS

Improved HFE may increase healthy eating among ethnic minorities but is unlikely to reduce unhealthy eating.

Dietary and physical activity behaviors of New York City children from different ethnic minority subgroups

OBJECTIVE

To examine racial/ethnic differences in diet and physical activity behaviors in ethnic minority New York City children.

METHODS

Cross-sectional data from a community-based study of 486 6- to 8-year-old children were used. Race/ethnicity was derived using a caregiver's report of child's race and Hispanic ancestry. Dietary intake was obtained by 24-hour diet recalls using the Nutrition Data System for Research. Physical activity was assessed with pedometers and caregiver interviews. We compared diet and activity measures across racial/ethnic subgroups using chi-square and analysis of variance tests. Multivariate analyses adjusted for age, gender, body mass index, and caregiver education (with breastfeeding history and total energy intake included in diet models).

RESULTS

Participants (N = 486) were categorized as Mexican (29.4%), Dominican (8.4%), Puerto Rican (20.6%), other/mixed Hispanic (14.0%), or non-Hispanic black (27.6%). Obesity rates were lower in non-Hispanic blacks (18%) than in Hispanics (31%). Mexicans had the lowest obesity rates among Hispanic subgroups (25%), and Dominicans had the highest (39%). There were differences in mean daily servings of food groups, with Mexicans having healthier diets and Puerto Ricans and non-Hispanic Blacks having less healthy diets. Sedentary time was lower in Mexicans than in other groups in adjusted models. Examination of additional models, including home language, did not show significant differences in the estimates.

CONCLUSION

Diet and activity behaviors varied across racial/ethnic subgroups. Specifically, Mexican children had healthier diets, the least amount of sedentary time, and the lowest rates of obesity among the Hispanic subgroups examined. Targeted interventions in ethnic subgroups may be warranted to address specific behaviors.

Gender differences in sociodemographic and behavioral influences of physical activity in Mexican-origin adolescents

BACKGROUND

Understanding the factors that contribute to physical activity (PA) in Mexican-origin adolescents is essential to the design of effective efforts to enhance PA participation in this population.

METHODS

Multivariable logistic regression was used to identify sociodemographic and behavioral correlates of self-reported PA in school and community settings in 1154 Mexican-origin adolescents aged 12-17 years in Houston, TX.

RESULTS

The majority of adolescents were born in the US (74%), approximately half (51%) were overweight or obese, and nearly three-quarters (73%) watched more than 2 hours of weekday television. Similarities and differences by setting and gender were observed in the relationships between sociodemographic and behavioral characteristics and PA. In boys, parental education and attending physical education (PE) were positively associated with PA across multiple PA outcomes. Adolescent linguistic acculturation was inversely associated with participation in community sports, whereas parental linguistic acculturation was positively associated with PA at school. In girls, PA in school and community settings was inversely associated with TV viewing and positively associated with PE participation.

CONCLUSIONS

These findings highlight similarities and differences in correlates of PA among boys and girls, and point toward potential sources of opportunities as well as disparities for PA behaviors in Mexican-origin adolescents.

Predictors of change in sports participation in Latino and non-Latino children

BACKGROUND

Few prospective studies have examined predictors of change in specific physical activity (PA) behaviours in different ethnic groups.

PURPOSE

To assess predictors of change in sports participation in Latino and non-Latino 5-8 year-old children in San Diego, California.

METHODS

Average sports participation frequency (days/week) was assessed by validated parent-report at baseline (Nov 2006-May 2008) and 1 year later in 541 children (45.0% male, 41.1% Latino; mean ± SD age: 6.6 ± 0.7 years) taking part in an obesity prevention study (Project MOVE). Biological (sex, age, Body Mass Index z-score), socio-cultural (ethnicity, income, care giver education), parental (PA rules, PA encouragement) and environmental factors (home PA equipment, PA location) were assessed at baseline. Associations between change in sports participation and potential predictors were studied using multilevel linear regression stratified by Latino ethnicity, adjusted for sex, baseline sport participation, study condition and recruitment area.

RESULTS

Sports participation increased over 1 year (mean change: +0.5 days; p<0.001) and change was similar for boys and girls (p=0.95), but Latino children showed a greater increase (p=0.03). The number of locations used for PA (p=0.024) and the total frequency of PA location use (p=0.018) were positively associated with increased sports participation among Latinos. No predictors were identified for non-Latino children.

CONCLUSIONS

Only factors relating to PA location were identified as predictors of change in sports participation for Latino children. Interventions targeting specific PA behaviours such as sports participation may need to consider PA locations for Latino children and be tailored for specific ethnic groups.

Experimenting with cigarettes and physical activity among Mexican origin youth: a cross sectional analysis of the interdependent associations among sensation seeking, acculturation, and gender

BACKGROUND

Sensation seeking tendencies tend to manifest during adolescence and are associated with both health-compromising behaviors and health-enhancing behaviors. The purpose of this study is to evaluate the relationship between sensation seeking and physical activity, a health-enhancing behavior, and between sensation seeking and experimenting with cigarettes, a health compromising-behavior, among a cohort of Mexican origin adolescents residing in the United States with different levels of acculturation.

METHODS

In 2009, 1,154 Mexican origin youth (50.5% girls, mean age 14.3 years (SD = 1.04)) provided data on smoking behavior, physical activity, linguistic acculturation, and sensation seeking. We conducted Pearson's χ2 tests to examine the associations between categorical demographic characteristics (i.e. gender, age, country of birth and parental educational attainment) and both cigarette experimentation and physical activity and Student's t-tests to examine mean differences on the continuous variables (i.e. sensation seeking subscale) by the behaviors. We examined mean differences in the demographic characteristics, acculturation, and both behaviors for each of the sensation seeking subscales using analysis of variance (ANOVA). To examine relationships between the sensation seeking subscales, gender, and both behaviors, at different levels of acculturation we completed unconditional logistic regression analyses stratified by level of acculturation.

RESULTS

Overall, 23.3% had experimented with cigarettes and 29.0% reported being physically active for at least 60 minutes/day on at least 5 days/week. Experimenting with cigarettes and being physically active were more prevalent among boys than girls. Among girls, higher levels of sensation seeking tendencies were associated with higher levels of acculturation and experimentation with cigarettes, but not with physical activity. Among boys, higher levels of sensation seeking tendencies were associated with higher levels of acculturation, experimenting with cigarettes and being physically active.

CONCLUSIONS

Our results suggest that interventions designed to prevent smoking among Mexican origin youth may need to address social aspects associated with acculturation, paying close attention to gendered manifestations of sensation seeking.

The effects of acculturation on healthy lifestyle characteristics among Hispanic fourth-grade children in Texas public schools, 2004-2005

BACKGROUND

Childhood obesity is a national epidemic that disproportionately affects Hispanic children. Evidence suggests that increased acculturation among this population adversely affects diet and other healthy lifestyle characteristics, leading to higher rates of overweight and obesity. Healthy lifestyle characteristics must be understood in order to prevent or decrease overweight and obesity among Hispanic children.

METHODS

Using the School Physical Activity and Nutrition (SPAN) study, we examined cross-sectional data on healthy lifestyle characteristics collected in Texas public schools from Hispanic fourth-grade children in 2004-2005. We calculated adjusted odds ratios and associated confidence intervals using multivariate logistic regression analyses to analyze the association between acculturation and healthy lifestyle characteristics among Spanish-speaking Hispanic children compared to English-speaking Hispanic children.

RESULTS

Spanish-speaking Hispanic boys consumed more milk and fruit than English-speaking Hispanic boys (milk: adjusted odds ratio [AOR]: 1.7, p = .02; fruit: AOR: 2.5, p = .0001). The likelihood that Spanish-speaking Hispanic boys and girls did not know that there is a relationship between overweight and health problems were 2 times greater (boys: AOR: 1.7, p = .03; girls: AOR: 2.2, p = .006) than their English-speaking Hispanic counterparts. Likelihood of weight loss attempts was greater among Spanish-speaking Hispanic boys than English-speaking Hispanic boys (AOR: 1.9, p = .04).

CONCLUSIONS

Results are mixed. Lower levels of acculturation appear to be associated with both positive and negative healthy lifestyle characteristics, depending on sex. These findings have important implications for school health policies and programs and should be distributed to school administrators.

Influence of body mass index, gender, and Hispanic ethnicity on physical activity in urban children

PURPOSE

This community-based participatory research study examined the association between overweight status and activity among Hispanic urban, school-age children.

DESIGN AND METHODS

In a sample of 140 children, activities were assessed using the Youth Risk Behavior Survey's questions about physical activity (PA) and team sports.

RESULTS

Thirty-nine percent were overweight (body mass index [BMI] >85%). Normal-weight children had higher levels of PA and team sports. Females had lower levels of PA and team sports. Significant associations included BMI and sports team participation, and BMI and Hispanic ethnicity.

PRACTICE IMPLICATIONS

Nurses should be aware that Hispanic urban children are at risk for lower activity.

School's out: what are urban children doing? The Summer Activity Study of Somerville Youth (SASSY)

Background

Research indicates that in the United States, children experience healthier BMI and fitness levels during school vs. summer, but research is limited. The primary goal of this pilot study was to assess where children spend their time during the months that school is not in session and to learn about the different types of activities they engage in within different care settings. A secondary goal of this pilot study was to learn what children eat during the summer months.

Methods

A nine-week summer study of 57 parents of second and third grade students was conducted in an economically, racial/ethnically and linguistically diverse US urban city. Weekly telephone interviews queried time and activities spent on/in 1) the main caregiver's care 2) someone else's care 3) vacation 4) and camp. Activities were categorised as sedentary, light, moderate, or vigorous (0-3 scale). For each child, a mean activity level was calculated and weighted for proportion of time spent in each care situation, yielding a weighted activity index. On the last phone call, parents answered questions about their child's diet over the summer. Two post-study focus groups were conducted to help interpret findings from the weekly activity interviews.

Results

The mean activity index was 1.05 ± 0.32 and differed between gender (p = 0.07), education (p = 0.08) and primary language spoken in the household (p = 0.01). Children who spent a greater percentage of time in parent care had on average a lower activity index (β = -0.004, p = 0.01) while children who spent a greater percentage of time in camp had a higher activity index (β = 0.004, p = 0.03). When stratified into type of camp, percentage of time spent in active camp was also positively associated with mean activity index (β = 0.005, p =< 0.001). With regards to diet, after adjusting for maternal education, children who attended less than five weeks of camp were four times more likely to eat their meals in front of the TV often/almost all of the time (OR = 4.0, 95%CI 1.0-16.2, p < 0.06).

Conclusions

Summer activities and some dietary behaviours are influenced by situation of care and socio-demographic characteristics. In particular, children who spend a greater proportion of time in structured environments appear to be more active. We believe that this pilot study is an important first step in our understanding of what children do during the summer months.

Generation, language, body mass index, and activity patterns in Hispanic children

BACKGROUND

The acculturation hypothesis proposes an overall disadvantage in health outcomes for Hispanic immigrants with more time spent living in the U.S., but little is known about how generational status and language may influence Hispanic children's relative weight and activity patterns.

PURPOSE

To investigate associations among generation and language with relative weight (BMI z-scores), physical activity, screen time, and participation in extracurricular activities (i.e., sports, clubs) in a U.S.-based, nationally representative sample of Hispanic children.

METHODS

Participants included 2012 Hispanic children aged 6-11 years from the cross-sectional 2003 National Survey of Children's Health. Children were grouped according to generational status (first, second, or third), and the primary language spoken in the home (English versus non-English). Primary analyses included adjusted logistic and multinomial logistic regression to examine the relationships among variables; all analyses were conducted between 2008 and 2009.

RESULTS

Compared to third-generation, English speakers, first- and second-generation, non-English speakers were more than two times more likely to be obese. Moreover, first-generation, non-English speakers were half as likely to engage in regular physical activity and sports. Both first- and second-generation, non-English speakers were less likely to participate in clubs compared to second- and third-generation, English speakers. Overall, non-English-speaking groups reported less screen time compared to third-generation, English speakers.

CONCLUSIONS

The hypothesis that Hispanics lose their health protection with more time spent in the U.S. was not supported in this sample of Hispanic children.
