“…Reasons for exclusion included: 18 studies performed conventional statistical analyses (e.g. regression analysis) rather than SNA (7,8,(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44), and the remaining one did not collect and report body weight and social network data (45). One additional article was identified through the backward and forward search (46).…”

People's health behaviours and outcomes can be profoundly shaped by the social networks they are embedded in. Based on graph theory, social network analysis is a research framework for the study of social interactions and the structure of these interactions among social actors. A literature search was conducted in PubMed and Web of Science for articles published until August 2017 that applied social network analysis to examine obesity and social networks. Eight studies (three cross-sectional and five longitudinal) conducted in the US (n = 6) and Australia (n = 2) were identified. Seven focused on adolescents' and one on adults' friendship networks. They examined structural features of these networks that were associated with obesity, including degree distribution, popularity, modularity maximization and K-clique percolation. All three cross-sectional studies that used exponential random graph models found individuals with similar body weight status and/or weight-related behaviour were more likely to share a network tie than individuals with dissimilar traits. Three longitudinal studies using stochastic actor-based models found friendship network characteristics influenced change in individuals' body weight status and/or weight-related behaviour over time. Future research should focus on diverse populations and types of social networks and identifying the mechanisms by which social networks influence obesity to inform network-based interventions.

“…Findings regarding the role of social support in weight status and weight loss behaviors in Latinos have been mixed. Studies have demonstrated that social support for exercise from family and/or friends is positively associated with motivation to change behaviors, physical activity, and weight loss among Hispanic adults ( Ashida, Wilkinson, & Koehly, 2012 ; Marquez et al, 2016 ; Marquez & McAuley, 2006 ; Winston et al, 2015 ). However, having obese members in one’s social network, having a larger social network, and receiving negative opinions regarding physical activity from sources of social support are associated with weight gain among Hispanic adults ( Winston et al, 2015 ).…”

“…As such, the role of social support and the source of social support as it relates to weight status remains unclear. In addition to the need to better understand the role of social support in health behaviors and outcomes, the existing research is limited in that studies are often focused on women, are majority or only Mexican, and/or do not provide explicit information about the country of origin or ethnicity ( Ashida et al, 2012 ; Wang, Pbert, & Lemon, 2014 ; Winston et al, 2015 ). Latinos/Hispanics are a heterogeneous group with a range of ethnic backgrounds and cultural practices ( Sanchez-Johnsen, 2011 ; Santiago-Rivera et al., 2002 ).…”

Social Support for Exercise as a Predictor of Weight and Physical Activity Status Among Puerto Rican and Mexican Men: Results From the Latino Men’s Health Initiative

et al. 2018

Social support is an important factor in increasing positive health outcomes and positive health behaviors across a variety of disease states including obesity. However, research examining the relationship between social support for exercise and weight and physical activity status, particularly among Latino men, is lacking. This paper examined whether social support for exercise predicted weight and physical activity status and whether the direction of these relationships differ as a function of Hispanic/Latino background (Puerto Rican/Mexican). Participants were 203 men who participated in a National Institutes of Health (NIH)-funded study addressing culture- and obesity-related variables. Both family participation social support and family rewards and punishment social support predicted higher weight status (p < .005 and p < .05, respectively). Friend participation social support did not predict weight status. The direction of the relationship between weight status and family participation social support, family rewards and punishment social support, and friend participation social support did not significantly differ as a function of Hispanic/Latino background. The direction of the relationship between physical activity status and family participation social support, family rewards and punishment social support, and friend participation social support did not significantly differ as a function of Hispanic/Latino background. Findings suggest that increased social support for exercise from family members may be focused on those who need it most—overweight and obese participants. Additional research is needed to explore sociocultural factors that may promote social support, physical activity, and weight loss and maintenance in Puerto Rican and Mexican men.

“…[8][9][10][11] This increased risk to children's health, in addition to the risk to the parents' health, highlights the need for effective weightloss interventions for parents. A recent study showed that adults lost more weight when their children were supportive of their weight loss efforts, 39 suggesting that parents may benefit from a family-centred approach to weight loss. Research is urgently needed to design effective interventions tailored to parents, particularly those who are racial/ethnic minorities who have a higher risk of obesity-related disease and may be disproportionally affected by the burdens of parenting.…”

Objective: Understand whether parents lose less weight than nonparents in behavioural weight interventions. Methods: The Look AHEAD (Action for Health in Diabetes) trial randomized adults with Type 2 diabetes and overweight to an intensive lifestyle intervention (ILI) or control (diabetes support and education [DSE]). Participants who reported living with a child under age 18 were designated as 'parents' for this analysis. Intention to treat analysis was performed of the effect of the ILI on change in weight at 1 year by parental status. Adherence to attending intervention visits was compared between parents and nonparents. Subgroup analyses were done based on previous subgroup findings in the Look AHEAD study. Results: Among 4,547 participants, 15% were parents. Parents were younger and more likely to have self-identified as African American or Hispanic/Latino. Comparing ILI with DSE, parents lost less weight than nonparents (−7.1% vs. −8.3%, p = 0.021). African American female parents lost 4% body weight compared with 7% in African American female nonparents (p = 0.01). Conclusions: In a randomized trial, parents lost less weight than nonparents, and this difference was largest for African American women. These findings suggest parents face unique challenges achieving weight loss; more research is needed to understand and optimize interventions for parents.
