Association of parental social support with energy balance-related behaviors in low-income and ethnically diverse children: a cross-sectional study

Home- and Community-Based Interventions for Physical Activity and Early Child Development: A Systematic Review of Effective Strategies

This systematic review examined the effects of home/family and community-based interventions on physical activity (PA) and developmental outcomes in early childhood. A search strategy was employed using four electronic databases (Academic Search Complete, CINAHL Complete, MEDLINE, and SPORTDiscus). Interventions investigating weight status (i.e., BMI), physical activity, sedentary behavior, and/or motor proficiency that took place in home, family, or community settings were assessed. Studies were eligible if they were peer-reviewed, available in English, published between 2011 and 2021, and if samples consisted of healthy young children (2-5 years old). There were 24 studies retained (8351 participants) spanning from the United States (n = 12), Australia (n = 3), Canada (n = 2), Switzerland (n = 2), Finland (n = 2), Netherlands (n = 1), and other Eastern European countries (n = 2). There were 19 studies that incorporated home/family-based approaches and 14 studies that incorporated community-based approaches. Studies ranged in intervention duration from 6 weeks to 24 months. It suggests that improving PA participation in young children was especially challenging to solicit improvement (only 25% of all studies found significant improvement in PA after intervention). Distributing educational material to parents/families, consistent, direct contact with parents, and encouraging community engagement were identified as effective strategies to promote physical activity, healthy weight status, and motor skills in young children.

Family Social Support and Weight-Related Behaviors of School-Age Children: An Exploratory Analysis

Families are a key provider of support that may encourage positive weight-related behaviors. Yet little is known about the relation of family support to children’s performance of weight-related behaviors. Mothers (N = 524) who completed an online survey were categorized as having low, moderate, or high family support for fruit/vegetable intake, breakfast intake, limiting sugar-sweetened beverage intake, physical activity, limiting sedentary screentime, and sleep. ANOVA revealed that children in families with high support for breakfast ate this meal significantly more often. Additionally, children in families with low support for limiting sugar-sweetened beverages had significantly greater intake. Surprisingly, families with moderate support for physical activity and sleep tended to have children with lower physical activity level, sleep duration, and sleep quality, and fewer days/week with set bedtimes than those with low and high support. Binomial logistic regression revealed that high family support for eating breakfast, limiting sugar-sweetened beverages, and getting sufficient sleep had greater odds of meeting recommendations for these behaviors. Findings suggest that greater family support for healthy weight-related behaviors tends to be associated with children’s performance of these behaviors. Future interventions should further examine the impact of different types of family support on weight-related behaviors to better understand this complex interplay.

Sugar-sweetened beverages consumption among New Zealand children aged 8-12 years: a cross sectional study of sources and associates/correlates of consumption

Background

The benefit of reducing sugar-sweetened beverage (SSB) consumption is widely accepted, but updated and in-depth data on New Zealand (NZ) children’s SSB consumption is lacking. The aims of this study were to describe beverage consumption, focusing on SSBs in primary school age children living in Auckland; to examine the association of selected socio-demographic, home, community and school factors and children’s beverage knowledge/attitudes with regards to beverage consumption; to explore the relationship between SSBs consumption and adiposity in children.

Methods

A cross-sectional, Auckland-wide survey of 578 school age children (8-12 years) was conducted using questionnaires to collect data on beverage consumption, beverage knowledge/attitudes, and selected socio-demographic and home, community, school factors. Body fat percentage (BF%) was assessed using bioelectrical impedance (BIA).

Results

Ninety-six percent of children consumed ≥1 serving of SSBs a week; with ≥5 servings reported by 62% of children. Of all SSBs assessed, consumption of ≥1 serving of sugar sweetened milk-based beverages (85%, mainly milk drinks made from powder) was most prevalent, followed by fruit juice (46%) and sugar-containing carbonated drinks (39%, mainly soft/fizzy drinks). Among unsweetened beverages, plain water was reported to be consumed < 2 times a day by 22% of children, and plain milk < 1 serving a day by 53%. Higher consumption of SSBs was associated with socio-economic disadvantage, non-NZ European ethnicities (Māori, Pacific, Asian, others), availability of SSBs in the home, frequent takeaway/convenience shop visits, children’s incorrect perception of adequate SSBs consumption frequency, and higher BF% (females only). School health policy and encouragement of children to consume un-sweetened beverages was not associated with SSBs consumption.

Conclusions

The consumption of SSBs is prevalent in NZ school age children, with higher consumption rates observed among those from socially disadvantaged areas. This high consumption is associated with higher BF% in females. Multi-contextual interventions to decrease SSBs should target children, and their families/environment, particularly those from socially disadvantaged areas.

Quantifying parent engagement in the randomized Fuel for Fun impact study identified design considerations and BMI relationships

BACKGROUND

Parent participation in children's health interventions is insufficiently defined and measured. This project quantified parent participation to enable future examination with outcomes in an intervention focused on 4th graders, aged 9-11 years, and their families living in northern Colorado.

METHODS

Indices were developed to measure type (Parent Participation Profile; PPP) and intensity (Parent Engagement Intensity; PEI) of engagement in Fuel for Fun (FFF), an asymmetric school-and family-based intervention for 4th graders. Study arm-specific participation opportunities were catalogued and summed to calculate the PPP. An algorithm considered frequency, effort, convenience, and invasiveness of each activity to calculate PEI. Indices were standardized (0-100%) using study arm-specific divisors to address asymmetric engagement opportunities. Parents who completed ≥75% of the PPP were defined as Positive Deviants. Youth height and weight were measured. Youth BMI percentile change was compared with parent Positive Deviant status using general linear modeling with repeated measures that included the participation indices.

RESULTS

Of 1435 youth, 777 (54%) had parent participation in at least one activity. Standardized means were 41.5 ± 25.4% for PPP and 27.6 ± 20.9% for PEI. Demographics, behaviors or baseline FFF outcomes did not differ between the Positive Deviant parent (n = 105) and non-Positive Deviant parents (n = 672); but more Positive Deviant parents followed an indulgent feeding style (p = 0.015). Standardized intensity was greater for Positive Deviant parents; 66.9 ± 20.6% vs 21.5 ± 12.7% (p < 0.001) and differences with non-Positive Deviant parents were related to activity type (p ≤0.01 for six of eight activities). Standardized participation intensity was associated with engagement in a greater number of standardized activity types. Among participating parents, standardized intensity and breadth of activity were inversely related to the youth BMI percentile (n = 739; PEI r = -0.39, p < 0.001; PPP r = -0.34, p < 0.001). Parent engagement was not associated with parent BMI change.

CONCLUSIONS

An activity-specific intensity schema operationalized measurement of parent engagement in a complex, unbalanced research design and can serve as a template for more sensitive assessment of parent engagement. Positive deviance in parent engagement was not a function of personal, but rather activity characteristics. PPP and PEI increased with fewer requirements and convenient, novel, and personalized activities. Parent engagement indices affirmed lower engagement by parents of overweight/obese youth and concerns about target reach.

Paternal and maternal support of moderate-to-vigorous physical activity in children on weekdays and weekends: a cross-sectional study

BACKGROUND

Most studies of associations between parental support behaviours for physical activity (PA) and children's moderate-to-vigorous physical activity (MVPA) have been conducted in developed countries, and they have focused on maternal or parental support behaviours. Children's MVPA time (i.e., weekdays vs. weekends) has not been adequately differentiated. This paper investigated the associations of paternal and maternal support behaviours for PA with the proportion of children who met the MVPA recommendations on weekdays and weekends in China.

METHODS

Cross-sectional data of 517 father-child dyads and 1422 mother-child dyads were analysed. The children recorded PA diaries on 7 consecutive days to assess their MVPA time. The father or mother completed a questionnaire concerning their support for children's PA. Multivariate logistic regression was used to investigate the independent effects of paternal and maternal support behaviours for PA on whether children met the MVPA recommendations for weekdays, weekends, and the whole week.

RESULTS

Significantly fewer children met the MVPA recommendations on weekends (37.8%) than on weekdays (62.8%). Higher paternal (odds ratio [OR] = 1.098, 95% confidence interval [CI]: 1.009-1.195) and maternal (OR = 1.076, 95% CI: 1.021-1.134) total support behaviour scores were associated with higher odds of children meeting the MVPA recommendations on weekends, after controlling for covariates. Paternal PA knowledge-sharing with the child was positively associated with children meeting the MVPA recommendations on weekends (OR = 1.319, 95% CI: 1.055-1.649); it tended to be associated with children meeting the MVPA recommendations on weekdays and throughout the week, although these associations were not statistically significant. Maternal reservation of PA time for the child was positively associated with a higher likelihood of children meeting the MVPA recommendations on weekdays (OR = 1.160, 95% CI: 1.025-1.313), weekends (OR = 1.241, 95% CI: 1.097-1.403), and throughout the week (OR = 1.214, 95% CI: 1.076-1.369).

CONCLUSIONS

Paternal and maternal support behaviours for PA should be enhanced on weekends to increase children's MVPA. Fathers should share PA knowledge with children and mothers should reserve PA time for children every day.

Is the Perceived Fruit Accessibility Related to Fruit Intakes and Prevalence of Overweight in Disadvantaged Youth: A Cross-Sectional Study

Background: Few investigations have studied the relationship between home and school food environments, fruit intakes, and prevalence of overweight in children and adolescents from disadvantaged backgrounds. This study aimed to determine whether food environments for fruit intake at household and school levels affect fruit intakes and risk of overweight among children and adolescents with low household income. Methods: Students (n = 3148) in Seoul, Korea completed questionnaires pertaining to select aspects of their food environments, frequency of fruit intakes, and weight status. Chi-square tests and logistic regressions evaluated associations between the aforementioned variables. Results: Participants consumed fruit an average of 0.77 times per day, though its frequency increased when fruit accessibility was perceived positively. The percentage of overweight participants was 23.5% for boys and 22.8% for girls. Generally, fruit intake frequency was linked to a lower prevalence of overweight. Regular provision of fruit in school lunches was associated with a reduced risk of overweight among elementary school girls (odds ratio (OR): 0.52, 95% confidence interval (CI): 0.30–0.92), and having someone at home to prepare fruit was associated with a reduced risk of overweight in elementary school boys (OR: 0.64, 95% CI: 0.43–0.94) and girls (OR: 0.63, 95% CI: 0.43–0.93). Conclusions: The frequency of fruit intake was low among disadvantaged youth. Increasing access to fruit in their food environments appears to enhance consumption and lower the risk of overweight, especially for elementary school girls.

Using a sibling-adoption design to parse genetic and environmental influences on children's body mass index (BMI)

Dietary and physical activity behaviors formed early in life can increase risk for childhood obesity and have continued negative consequences for lifelong health. Previous research has highlighted the importance of both genetic and environmental (e.g., cultural environment or parental lifestyle) contributions to obesity risk, although these studies typically involve genetically-related individuals residing in the same household, where genetic similarity and rearing environment are inextricably linked. Here we utilize a sibling-adoption design to independently estimate genetic and environmental contributions to obesity risk in childhood and describe how these influences might vary as children age. As part of a prospective adoption study, the current investigation used data from biological siblings reared either apart or together, and nonbiological siblings reared together to estimate the contributions of genetics and environment to body mass indices (BMI) in a large cohort of children (N = 711). We used a variance partitioning model to allocate variation in BMI to that which is due to shared genetics, common environment, or unique environment in this cohort during middle childhood and adolescence. We found 63% of the total variance in BMI could be attributed to heritable factors in middle childhood sibling pairs (age 5-11.99; 95% CI [0.41,0.85]). Additionally, we observed that common environment explained 31% of variation in BMI in this group (95% CI [0.11,0.5]), with unique environment and error explaining the remaining variance. We failed to detect an influence of genetics or common environment in older sibling pairs (12-18) or pairs spanning childhood and adolescence (large sibling age difference), but home type (adoptive versus birth) was an important predictor of BMI in adolescence. The presence of strong common environment effects during childhood suggests that early interventions at the family level in middle childhood could be effective in mitigating obesity risk in later childhood and adolescence.

Family Encouragement of Healthy Eating Predicts Child Dietary Intake and Weight Loss in Family-Based Behavioral Weight-Loss Treatment

Introduction: Social support for healthy eating can influence child eating behaviors; however, little is known about the impact of social support during family-based behavioral weight-loss treatment (FBT). This study aimed to determine the impacts of both baseline and change in family support on change in child diet and weight during FBT. Methods: Children (n = 175; BMI percentile ≥85th; ages 7-11; 61.1% female; 70.9% white) and a participating parent completed 4 months of FBT. Parents were active participants and learned social support-related strategies (i.e., praise and modeling of healthy eating). Child perceived family encouragement and discouragement for healthy eating, child diet quality (via 24-hour recalls), and child weight were assessed pre- and post-FBT. Results: Family encouragement for healthy eating increased during FBT, and this increase was related to increases in child healthy vegetable intake and overall diet quality, as well as decreases in refined grains consumed. Low pre-FBT family encouragement predicted greater increases in healthy vegetable intake, greater weight reduction, and greater increases in family encouragement for healthy eating. Family discouragement for healthy eating did not change during treatment nor did it predict dietary or weight outcomes. Conclusions: FBT successfully improves family encouragement, which is associated with improvements in child diet. Furthermore, even children who began treatment with low family encouragement for healthy eating show great improvements in dietary intake and weight during treatment. Results suggest that changes in child eating behavior during treatment is influenced by active, positive parenting techniques such as praise of healthy eating rather than negative family support.

Gender-specific correlates of sufficient physical activity among vulnerable children

AIM

We aimed to identify the levels and types of physical activity (PA) by gender, and to determine correlates of sufficient PA on a theoretical basis of self-determination and social support; moreover, if significant correlates with sufficient PA would differ by gender among vulnerable children.

METHODS

Participants were 319 children enrolled in public welfare systems in Seoul, South Korea. Sufficient PA was defined as daily activity with moderate or vigorous intensity for 60 min. Self-determined motivation was assessed by autonomous and controlled forms; social support was assessed as two types: family and peer support. Questionnaires were self-reported by children and their parents.

RESULTS

Of the participants, 20.4% achieved sufficient PA, specifically 15.0% for girls versus 27.3% for boys (P < .001). Girls were more likely to perform casual exercise types, while boys were more likely to perform sports types (P < .05 for all). The autonomous form of self-determined motivation, but not its controlled form, was significantly associated with sufficient PA in both girls (adjusted odds ratio [AOR] = 2.03, P = .028) and boys (AOR = 2.47, P = .007). Family support was not significantly associated in girls and boys; however, peer support was significantly associated only in boys (AOR = 3.72, P = .042).

DISCUSSION

Of the children, girls were less likely to achieve sufficient PA and to perform sports than were boys. Self-determined motivation was a PA correlate uniformly in girls and boys; however, peer support was a PA correlate only in boys. Self-determined motivation-enhanced strategies should be integrated with peer support provided through gender-specific strategies when employing a PA intervention for vulnerable children.

US Pediatrician Practices and Attitudes Concerning Childhood Obesity: 2006 and 2017

OBJECTIVE

To compare primary care pediatricians' practices and attitudes regarding obesity assessment, prevention, and treatment in children 2 years and older in 2006 and 2017.

STUDY DESIGN

National, random samples of American Academy of Pediatrics members were surveyed in 2006, 2010, and 2017 on practices and attitudes regarding overweight and obesity (analytic n = 655, 592, and 558, respectively). Using logistic regression models (controlling for pediatrician and practice characteristics), we examined survey year with predicted values (PVs), including body mass index (BMI) assessment across 2006, 2010, and 2017 and practices and attitudes in 2006 and 2017.

RESULTS

Pediatrician respondents in 2017 were significantly more likely than in 2006 and 2010 to report calculating and plotting BMI at every well-child visit, with 96% of 2017 pediatricians reporting they do this. Compared with 2006, in 2017 pediatricians were more likely to discuss family behaviors related to screen time, sugar-sweetened beverages, and eating meals together, P < .001 for all. There were no observed differences in frequency of discussions on parental role modeling of nutrition and activity-related behaviors, roles in food selection, and frequency of eating fast foods or eating out. Pediatricians in 2017 were more likely to agree BMI adds new information relevant to medical care (PV = 69.8% and 78.1%), they have support staff for screening (PV = 45.3% and 60.5%), and there are effective means of treating obesity (PV = 36.3% and 56.2%), P < .001 for all.

CONCLUSIONS

Results from cross-sectional surveys in 2006 and 2017 suggest nationwide, practicing pediatricians have increased discussions with families on several behaviors and their awareness and practices around obesity care.

Examining the Validity, Reliability, and Measurement Invariance of the Social Support for Exercise Scale among Spanish- and English- language Hispanics

The Social Support for Exercise Subscales are commonly used among Hispanic populations. The aims of this study were to test the validity and reliability of the Spanish-language version of the Social Support for Exercise Subscales, and test the invariance of the Spanish- and English-language versions. Data were from a subsample of Hispanic adults in the Cameron County Hispanic Cohort (n=1,447). A series of confirmatory factor analysis (CFA) models were used to assess the validity and reliability of the Spanish-language version of the subscales. A multi group CFA approach was used to test measurement invariance. Results indicated the Spanish-language versions of family and friend support subscales had good validity and reliability (RMSEA<.07, CFI>0.95, TLI>0.94, and SRMR<0.05). There was also evidence of measurement invariance between the Spanish- and English-language versions. These findings indicate the Spanish-language family and friend support subscales are valid and can be compared between Spanish- and English-language Hispanic respondents.

Within-Subject Associations of Maternal Physical Activity Parenting Practices on Children's Objectively Measured Moderate-to-Vigorous Physical Activity

OBJECTIVE

Longitudinal within-subject (WS) associations of mothers' momentary assessed physical activity (PA) parenting practices were examined with children's objectively measured PA during the same 2-hr time frame.

METHOD

Mother-child dyads (n = 189) completed five ecological momentary assessment (EMA) measurement bursts over 3 years. During each 7-day burst, mothers EMA-reported their past 2 hr PA parenting practices (i.e., encouraging their child to be physically active, taking their child someplace to be physically active), and children (Mage=9.6 years, SD = 0.9) wore an accelerometer to measure moderate-to-vigorous PA (MVPA). Two-part multilevel models were used, with zero portions representing not meeting MVPA and positive portions representing any MVPA, controlling for demographic covariates. Cross-level interaction terms of child sex and age with parenting were created to test moderation effects.

RESULTS

When mothers reported taking their child to be physically active, children were more likely to get some MVPA (b = -0.56, p < .001). When mothers reported taking their child to be physically active more, children had higher levels of MVPA (b = 0.24, p < .001). When mothers reported encouraging their child to be physically active, children were less likely to get any MVPA (b = 0.27, p < .05). However, when mothers reported encouraging their child to be physically active more, children had higher levels of MVPA (b = 0.29, p < .001). These effects were not moderated by child sex or age.

CONCLUSIONS

WS variations of mothers' support for PA across the day were associated with changes in children's MVPA. Future research should consider promoting mothers' provision of support for increasing children's PA.

Longitudinal associations of family functioning with body mass index in Mexican-origin adolescents living in the U.S

Mexican-origin adolescents have a high prevalence of obesity. Research is needed to understand how family context may shape adolescent BMI. This study examined longitudinal associations of family functioning variables with the Centers for Disease Control and Prevention's modified BMI z-score (BMIaz) in 1175 Mexican-origin adolescents, and explored interactions with acculturation. Adolescents (50% female, aged 11-13 y in 2005-06) were identified from an ongoing cohort study of Mexican-origin adults in Houston, TX, and were assessed three times from 2005-06 to 2010-11. In multivariate linear mixed models stratified by gender, we assessed longitudinal associations of family cohesion and family conflict with adolescent BMIaz and explored interactions with language acculturation. We disaggregated the between- (mean) and within-person (individual deviation) components of family cohesion and family conflict to assess the effects on BMIaz. Approximately one-third of adolescents were obese at baseline, and BMIaz declined during the study. In girls, higher mean family cohesion and conflict were associated with steeper declines in BMIaz. Parental linguistic acculturation modified the relationship between within-person deviation in family cohesion and BMIaz in girls, such that high parental U.S. acculturation was associated with a stronger inverse association. There were no significant associations in boys. These findings highlight the potential importance of the family context to female adolescent BMI and the promise of addressing family context in obesity-related interventions.

Alabama Children's Body Mass Index, Nutritional Attitudes, and Food Consumption: An Exploratory Analysis

OBJECTIVES

This study had three aims: assess the extent to which middle school children in southern Alabama were classified as overweight or obese; determine the magnitude of the relation between children's attitudes toward healthy eating and their actual dietary choices; and examine the role of race, sex, and ZIP codes on children's eating attitudes and behaviors.

METHODS

Registered dietitians took height and weight measurements of middle school children in southern Alabama to establish body mass index (BMI). Children were given a Likert-type survey with multiple-choice items to assess the study's objectives. Descriptive statistics were generated, and structural equation modeling was used to examine potential moderating effects on the associations between a latent variable of healthy eating attitudes and a latent variable of healthy eating behaviors across race and ethnicity. A series of analyses of variance was used to determine any significant differences in the children's attitudes across schools. The χ² tests were used to examine potential race differences in BMI.

RESULTS

A total of 630 children participated in the study. Their average age was 12 years. More than half (53%) of the children were girls, and more than half (61%) were White. Approximately one-third (29%) identified as Black/African America. A large proportion of children across the sample (42.3%) were classified as overweight or obese. The multigroup structural equation modeling yielded a significant direct path between healthy attitudes and healthy eating behaviors. Healthy eating attitudes strongly predicted intentions toward healthy eating behaviors for children classified as normal weight and for those children classified as overweight or obese. Children's BMI classifications did not differ significantly across schools, race, or sex.

CONCLUSIONS

A large percentage of children in south Alabama were classified as overweight or obese, conditions that are preventable. Moreover, evidence suggests a lack of nutritious food in their diets. Children overall endorsed healthy eating attitudes, and those attitudes were strongly related to healthy food choices; however, their level of healthy food consumption was not related to their BMI classification. Although children in this study were from three schools and represented a variety of racial, sex, and socioeconomic systems, there were more similarities than differences in their healthy eating attitudes or behavior. These similarities highlight the need for research to examine other factors, such as southern culture, as a potential contributor to childhood obesity.

Gain-Framed Messages Were Related to Higher Motivation Scores for Sugar-Sweetened Beverage Parenting Practices than Loss-Framed Messages

Parents play an important role in promoting healthy beverage intake among children. Message-framing approaches, where outcomes are described as positive (gain) or negative (loss) results, can be used to encourage parenting practices that promote healthy beverage intakes. This study tested the effectiveness of message framing on motivation for parenting practices targeting reductions in child sugar-sweetened beverage (SSB) intake (controlling availability, role modeling) and dispositional factors moderating effectiveness. Parents (n = 380) completed a survey to assess motivation after viewing gain- and loss-framed messages to engage in parenting practices, usual beverage intake, and home beverage availability. Paired t-tests were used to examine differences in motivation scores after viewing gain- vs. loss-framed messages for all parents and by subgroups according to low vs. high SSB intake and home availability, and weight status. Gain- versus loss-framed messages were related to higher motivation scores for both parenting practices for all parents (n = 380, p < 0.01) and most subgroups. No differences were observed by message frame for parents in low home SSB availability or normal and overweight BMI subgroups for controlling availability. Gain- versus loss-framed messages were related to higher motivation scores, therefore gain-framed messages are recommended for parent interventions intended to decrease child intake of SSBs.
