Changes in diet quality and home food environment in preschool children following weight management.

ABSTRACT: BACKGROUND:Family-based obesity treatment interventions can successfully reduce energy intake in preschoolers. An implicit goal of obesity treatment interventions is to improve diet quality, but diet quality has been less examined as a treatment outcome in studies of preschoolers. The purpose of this study was to conduct a secondary analysis comparing the change in diet quality and home food environment in preschoolers assigned to a behavioral family-based obesity intervention (LAUNCH), motivational interviewing (MI) condition, or standard care (STC) condition. METHODS:Three 24-h dietary recalls were completed at baseline and 6-months and were analyzed using NDS-R software; diet quality was assessed using the Healthy Eating Index-2010 (HEI-2010). Availability of foods and beverages in the home was assessed through direct observation using the Home Health Environment tool that classifies foods and beverages as 'red' or 'green' based upon fat and sugar content. Repeated measures linear mixed effects models were used to examine changes in diet quality and home food environment between conditions (LAUNCH, MI, STC). RESULTS:At 6-months, preschoolers in the LAUNCH condition had a higher HEI-2010 total score (62.8?±?13.7) compared to preschoolers in the MI (54.7?±?13.4, P?=?0.022) and STC (55.8?±?11.6, P?=?0.046) conditions. Regarding the home food environment, families in LAUNCH had significantly less 'red' foods in their home at 6-months (12.5?±?3.4 'red' foods) compared to families in MI (14.0?±?3.7 'red' foods, P?=?0.030), and STC (14.3?±?3.4 'red' foods, P?=?0.006). There were no statistically significant differences across home food environments for number of 'green' foods. CONCLUSION:Family-based obesity treatment interventions for preschoolers can improve overall diet quality and alter the home food environment through reductions in 'red' foods.

Project description:ObjectivesThe home environment is thought to play a key role in early weight trajectories, although direct evidence is limited. There is general agreement that multiple factors exert small individual effects on weight-related outcomes, so use of composite measures could demonstrate stronger effects. This study therefore examined whether composite measures reflecting the 'obesogenic' home environment are associated with diet, physical activity, TV viewing, and BMI in preschool children.MethodsFamilies from the Gemini cohort (n = 1096) completed a telephone interview (Home Environment Interview; HEI) when their children were 4 years old. Diet, physical activity, and TV viewing were reported at interview. Child height and weight measurements were taken by the parents (using standard scales and height charts) and reported at interview. Responses to the HEI were standardized and summed to create four composite scores representing the food (sum of 21 variables), activity (sum of 6 variables), media (sum of 5 variables), and overall (food composite/21 + activity composite/6 + media composite/5) home environments. These were categorized into 'obesogenic risk' tertiles.ResultsChildren in 'higher-risk' food environments consumed less fruit (OR; 95% CI = 0.39; 0.27-0.57) and vegetables (0.47; 0.34-0.64), and more energy-dense snacks (3.48; 2.16-5.62) and sweetened drinks (3.49; 2.10-5.81) than children in 'lower-risk' food environments. Children in 'higher-risk' activity environments were less physically active (0.43; 0.32-0.59) than children in 'lower-risk' activity environments. Children in 'higher-risk' media environments watched more TV (3.51; 2.48-4.96) than children in 'lower-risk' media environments. Neither the individual nor the overall composite measures were associated with BMI.ConclusionsComposite measures of the obesogenic home environment were associated as expected with diet, physical activity, and TV viewing. Associations with BMI were not apparent at this age.

Project description:BackgroundHome food procurement (HFP) (i.e. gardening, fishing, foraging, hunting, backyard livestock and canning) have historically been important ways that people obtain food. Recently, some HFP activities have grown (e.g. gardening), while other activities (e.g. hunting) have become less common in the United States. Anecdotally, COVID-19 has sparked an increase in HFP evidenced by increased hunting licenses and shortages in seeds and canning supplies. HFP may have positive benefits for food security and diet quality, though research beyond gardening is especially limited in high-income countries.MethodsWe examine HFP activities since the COVID-19 pandemic began, and their relationship to food security and dietary quality using multivariable logit models and matching analysis with a statewide representative survey (n = 600) of residents of Vermont, United States.ResultsWe find 29% of respondent households classified as food insecure since COVID-19, and higher prevalence of food insecurity among those experiencing a negative job change since COVID-19, households earning less than $50,000 annually, Hispanic and multi-race respondents. Nearly 35% of respondents engaged in HFP activities since the COVID-19 pandemic began; the majority of those gardened, and more than half pursued HFP activities more intensely than before the pandemic or for the first time. Food insecure households were more likely to pursue HFP more intensely, including more gardening, fishing, foraging, and hunting. Respondents who were food insecure, Black, Indigenous, People of Color, those with a negative job disruption, and larger households all had greater odds of increased intensity of HFP during the COVID-19 pandemic. HFP was significantly associated with eating greater amounts of fruits and vegetables; however, this effect was only significant for food secure households.ConclusionOverall, these results suggest that HFP activities have increased since the start of the COVID-19 pandemic, and may be an important safety net for food insecure households. However, HFP for food insecure households does not translate into the same higher fruit and vegetable intake as found among food secure HFP households, suggesting this population may be trying to maintain intake, or that they may have potential important resource or technical assistance needs. Long-term, HFP activities may have important food security and diet quality impacts, as well as conservation implications, which should be more thoroughly explored. Regardless, the increased interest and intensity of HFP demonstrates opportunities for educational and outreach efforts.

Project description:Background:Reductions in energy intake are seen in weight loss trials, but whether this occurs with improvements to diet quality (DQ) is less established. The aim of this study was to evaluate changes in diet quality in a sample of volunteers in a weight loss trial. Methods:This was a secondary analysis of dietary data from a lifestyle intervention trial (the HealthTrack study) which advised on dietary guidelines. The trial ran for 12 months with three treatment groups: control (general advice C), intervention (individualised advice, I), and intervention plus a supplement of walnuts (IW). Both the published a priori diet quality score (APDQS, maximum score 164) and a study specific Diet Quality Tracker (DQT, maximum score 44) indicated compliance to dietary advice. DQ scores calculated at 0, 3months and 12months were evaluated using two-way RMANOVA, one-way ANOVA and one-way RMANOVA. Changes in intakes of food groups and nutrients were analysed using Kruskal-Wallis and Friedman's tests. Results:There were no differences between groups at baseline, but at 3months IW recorded higher DQ scores (APDQS:96?±?10; DQT:22?±?5, P?<?1?×?10-3 for both) compared to I (APDQS:91?±?13, P?<?1?×?10-3; DQT:21?±?4, P?<?1?×?10-2) and C (APDQS:87?±?12, P?<?5?×?10-2; DQT:19?±?4, P?>?5?×?10-2), and a higher consumption of nuts at 3 months (P?<?1?×?10-3), and 12months (P?<?1?×?10-2). All groups reported decreased intakes of discretionary foods/beverages assessed by the DQT (P?<?1?×?10-3 for IW and I; P?<?1?×?10-2 for C). The APDQS showed this as reduced intakes of grain based desserts (P?<?1?×?10-3 at 3 and 12months), and salty snacks at 12months (P?<?1?×?10-3 for IW and I; P?<?5?×?10-2 for C). Intakes of monounsaturated and saturated fatty acids were lowest, and polyunsaturated fatty acids highest for IW (P?<?1?×?10-3), resulting in a higher dietary polyunsaturated:saturated fat ratio (P?<?1?×?10-3). Conclusions:Lifestyle intervention addressing dietary guidelines can lead to significant reductions in consumption of discretionary foods and saturated fat, but individualised advice may have a greater impact on improving overall DQ regardless of DQI used. Providing a healthy food supplement may help assure higher DQ and where the food is walnuts, produce commensurate differences in dietary fatty acid profiles.
