Dual burden of malnutrition in US Affiliated Pacific jurisdictions in the Children's Healthy Living Program.

ABSTRACT: Few data are available on dual burden of under and over nutrition of children in the Pacific region. The objective was to examine prevalence of stunting at birth and current stunting and their relationship to obesity in US Affiliated Pacific (USAP) jurisdictions.Cross sectional survey with cluster sampling by community. 5558, 2-8 years olds were measured in 51 communities in 11 USAP jurisdictions. The main outcome measures were stunting at birth, current stunting and obesity by body mass index. Prevalences of stunting at birth, current stunting and obesity were determined, adjusting for age distribution and community clustering. Differences by among age, sex, race and jurisdiction income levels were evaluated by chi-square analysis. Relationships of stunting at birth and current stunting with obesity were examined using a hierarchical model accounting for the study design.Prevalences were stunting at birth 6.8% (Standard Error, SE = 0.9%), current stunting 1.4% (SE = 0.2%) and obesity 14.03.8% (SE = 0.9%). Obesity was highest in upper middle income jurisdictions (UMIJ) at 17.5%. Stunting at birth differed by race (p = 0.0001) with highest prevalence among Native Hawaiian/Pacific Islanders (10.7%). Prevalence of stunting at birth was different by jurisdiction income level with 27.5% in lower middle income jurisdictions (LMIJ), and 22.2% in UMIJ, and 5.5% in higher than high income jurisdictions (HIJ) at 5.5% (p < 0.0001). Prevalence of current stunting was higher in LMIJ than HIJ (p = 0.001), although children with current stunting were less likely to have been stunted at birth. The association between stunting at birth and current stunting was negative (OR = 0.19, 95% CI: 0.05-0.69).Currently stunted children were marginally less likely to be obese than not stunted children in the USAP, where the prevalence of current stunting is low. Stunting (at birth and current) was highest in LMIJ, while UMIJ jurisdictions had the highest dual burden of malnutrition (that is the highest combination of both stunting at birth and obesity).National Institutes for Health clinical trial # NCT01881373 (clinicaltrials.gov).

Project description:Importance:Pacific Islanders have among the highest rates of obesity and type 2 diabetes in the world. Targeting children is critical for primary prevention. Objectives:To prevent young child overweight and obesity and to improve health in the US-Affiliated Pacific region via the Children's Healthy Living Program. Design, Setting, and Participants:In this multijurisdictional, multilevel, multicomponent community randomized clinical trial, where all evaluable children were analyzed according to the random assignment of their community, hierarchical difference-in-difference models accounted for the community randomization, community clustering with jurisdictions, and these models were adjusted for the age and sex distribution of the community. The setting was 27 communities in 5 jurisdictions (Alaska, American Samoa, Commonwealth of the Northern Mariana Islands, Guam, and Hawaii). Participants were 4329 children (time 1) and 4042 children (time 2) aged 2 to 8 years in 27 selected communities from October 7, 2012, to October 25, 2015. Data analysis was completed in June 2018. Interventions:Nineteen activities addressed policy, environment, messaging, training, and 6 target behaviors (sleep time, screen time, physical activity, fruits and vegetables, water, and sugar-sweetened beverages). Main Outcomes and Measures:Primary outcomes were body size measurements. Secondary outcomes were acanthosis nigricans, sleep quality and duration, dietary intake, physical activity, and other questionnaire reponses. Results:The study included 27 communities and 8371 evaluable children (mean [SD] age, 5.4 [1.8] years; 50.9% male [n?=?4264]). Data analysis included 952 children in the intervention group and 930 children in the control group aged 2 to 5 years at time 1; 825 children in the intervention group and 735 children in the control group aged 2 to 5 years at time 2; 565 children in the intervention group and 561 children in the control group aged 6 to 8 years at time 1; and 517 children in the intervention group and 560 children in the control group aged 6 to 8 years at time 2. The intervention communities showed significant improvement compared with control communities in overweight and obesity prevalence (effect size [d]?=?-3.95%; 95% CI, -7.47% to -0.43%), waist circumference (d?=?-0.71 cm; 95% CI, -1.37 to -0.05 cm), and acanthosis nigricans prevalence (d?=?-2.28%; 95% CI, -2.77% to -1.57%). Age and sex subgroup analysis revealed greater difference among the intervention communities in acanthosis nigricans prevalence in the group aged 2 to 5 years (-3.99%) vs the group aged 6 to 8 years (-3.40%), and the interaction was significant (d?=?0.59%, P?<?.001), as well as the smaller difference in the group aged 2 to 5 years (-0.10%) vs the group aged 6 to 8 years (-1.07%) in screen time (d?=?-0.97 hour per day, P?=?.01). Conclusions and Relevance:The intervention reduced the prevalence of young child overweight and obesity and acanthosis nigricans. Comprehensive, effective, and sustainable interventions are needed to improve child health in the US-Affiliated Pacific region. Trial Registration:ClinicalTrials.gov Identifier: NCT01881373.

Project description:ImportanceFew obesity prevention trials among children have demonstrated sustainable outcomes in the long term.ObjectivesTo sustain a community-wide decrease in the prevalence of overweight and obesity among young children in the US-affiliated Pacific region.Design, setting, and participantsIn the Children's Healthy Living community-randomized clinical trial, hierarchical modeling comparing the change in intervention and control communities accounted for community randomization (community clustering with jurisdictions), and adjusted for the age and sex distribution of the assessed children in a cross-sectional design. The outcome measures were repeated in communities rather than among individual children. A total of 27 communities in 5 jurisdictions (Hawai'i, Alaska, Commonwealth of the Northern Mariana Islands, American Samoa, and Guam) of the US-affiliated Pacific region were included. Participants included children aged 2 to 8 years in the 27 selected communities from October 1, 2012 (4329 in time 1 [baseline]) to August 31, 2015 (4043 in time 2 [intervention end]) and from January 1, 2019, to April 30, 2020 (1469 in time 3 [maintenance period]). Study analysis was completed March 25, 2022.InterventionsNineteen activities addressed training, policies, systems, and environments of communities and 6 target behaviors of children (consumption of fruit and vegetables, water, and sugar-sweetened beverages; sleep; physical activity; and screen time) during a 2-year intervention period. Continued partnership with community coalitions, ongoing academic training of community partners, and use of trial data during a 6-year maintenance period.Main outcomes and measuresThe primary outcome was measured anthropometry; secondary outcomes were the presence of acanthosis nigricans, dietary intake derived from 2 days of food records, and survey questions on screen time and sleep disturbance.ResultsAmong the 9840 children included in the analysis (4866 girls [49.5%] and 4974 boys [50.5%]; 6334 [64.4%] aged 2-5 years), the intervention group showed significant improvements compared with the control group from times 1 to 3 in prevalence of overweight plus obesity (d = -12.60% [95% CI, -20.92% to -4.28%]), waist circumference (d = -1.64 [95% CI, -2.87 to -0.41] cm), and acanthosis nigricans prevalence (d = -3.55% [95% CI, -6.17% to -0.92%]). Significant improvements were also observed from times 2 to 3 in prevalence of overweight plus obesity (d = -8.73% [95% CI, -15.86% to -1.60%]) but not in waist circumference (d = -0.81 [95% CI, -1.85 to 0.23] cm).Conclusions and relevanceThis randomized clinical trial found that the outcomes of the Children's Healthy Living intervention were maintained and enhanced 6 years after the intervention among young children in the US-affiliated Pacific region. The prevalence of overweight, obesity, and acanthosis nigricans was further reduced in communities, suggesting that multilevel multicomponent interventions may help reduce child overweight and obesity in this region.Trial registrationClinicalTrials.gov Identifier: NCT01881373.

Project description:BackgroundAlthough surveillance data are limited in the US Affiliated Pacific, Alaska, and Hawaii, existing data suggest that the prevalence of childhood obesity is similar to or in excess of other minority groups in the contiguous US. Strategies for addressing the childhood obesity epidemic in the region support the use of community-based, environmentally targeted interventions. The Children's Healthy Living Program is a partnership formed across institutions in the US Affiliated Pacific, Alaska, and Hawaii to design a community randomized environmental intervention trial and a prevalence survey to address childhood obesity in the region through affecting the food and physical activity environment.Methods/designThe Children's Healthy Living Program community randomized trial is an environmental intervention trial in four matched-pair communities in American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and Hawaii and two matched-pair communities in Alaska. A cross-sectional sample of children (goal n = 180) in each of the intervention trial communities is being assessed for outcomes at baseline and at 24 months (18 months post-intervention). In addition to the collection of the participant-based measures of anthropometry, diet, physical activity, sleep and acanthosis nigricans, community assessments are also being conducted in intervention trial communities. The Freely Associated States of Micronesia (Federated States of Micronesia, and Republics of Marshall Islands and Palau) is only conducting elements of the Children's Healthy Living Program sampling framework and similar measurements to provide prevalence data. In addition, anthropometry information will be collected for two additional communities in each of the 5 intervention jurisdictions to be included in the prevalence survey. The effectiveness of the environmental intervention trial is being assessed based on the RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework.DiscussionThe Children's Healthy Living Program environmental trial is designed to focus on capacity building and to maximize the likelihood of sustainable impact on childhood obesity-related behaviors and outcomes. The multiple measures at the individual, community, and environment levels are designed to maximize the likelihood of detecting change. This approach enhances the likelihood for identifying and promoting the best methods to promote health and well-being of the children in the underserved US Affiliated Pacific Region.Trial registrationNIH clinical trial # NCT01881373.

Project description:Background: Among contemporary human populations, rates of cesarean delivery vary substantially, making it difficult to know if the procedure is inadequately available, or used excessively relative to medical need. A much-cited evolutionary hypothesis attributed birth complications to an "obstetric dilemma," resulting from antagonistic selective pressures acting on maternal pelvic dimensions and fetal brain growth during hominin evolution. However, the childbirth challenges experienced by living humans may not be representative of those in the past, and may vary in association with trends in ecological conditions. We hypothesized that variability in maternal phenotype (height and nutritional status) may contribute to the risk of cesarean delivery. In many populations, high levels of child stunting contribute to a high frequency of short adult stature, while obesity is also becoming more common. The combination of short maternal stature and maternal overweight or obesity may substantially increase the risk of cesarean delivery. Methods: Using data from two large Indian health surveys from 2005-6 to 2015-2016, we tested associations of maternal somatic phenotype (short stature, overweight) with the risk of cesarean delivery, adjusting for confounding factors such as maternal age, birth order, rural/urban location, wealth and offspring sex. Results: Secular trends in maternal body mass index between surveys were greater than trends in height. Maternal short stature and overweight both increased the risk of cesarean delivery, most strongly when jointly present within individual women. These associations were independent of birth order, wealth, maternal age and rural/urban location. Secular trends in maternal phenotype explained 18% of the increase in cesarean rate over 10 years. Conclusion: Our results highlight how the emerging dual burden of malnutrition (persisting short adult stature which reflects persistent child stunting; increasing overweight in adults) is likely to impact childbirth in low and middle-income countries.

Project description:BACKGROUND:Healthy Together (HT) is family-centered program to support healthy eating and physical activity designed for implementation in community organizations serving families who may be experiencing vulnerabilities (e.g., related to low income, isolation, ethnicity, immigrant/refugee status, and/or Indigenous background). The purpose of this study was to conduct an evaluation of HT in a real-world, scale-up phase using the RE-AIM framework. METHODS:Using a cross-sectional, non-comparative design, a community-based program evaluation was conducted in 29 organizations implementing HT as part of their core service programs. Data were collected using questionnaires with program participants and facilitators, and interviews with directors of participating organizations. Quantitative data were analyzed using descriptive statistics and qualitative data were content analyzed. RESULTS:With regards to Reach, over 3400 caregivers, children and youth attended community programming that offered HT. Among those attending on the scheduled day for the evaluation, 663 completed the questionnaires. The majority of caregiver respondents (n?=?431) were female (92%) and attended with children 0-6?years. Respondents also included children 4-6?years (n?=?142) and 7-12?years (n?=?65), and youth 13-18?years (n?=?25). Effectiveness was demonstrated in reported improvements in physical activity, healthy eating, and strengthened social connections. HT was also widely supported by participants and facilitators. Adoption was influenced by the desire to enrich core service programs for families, HT's fit within existing programs, organizational commitment, and funding support. Implementation experiences indicated that fidelity to the HT program was generally maintained, with some setting specific adaptations. Maintenance of HT was influenced by financial and non-financial resources within community organizations. Most organizations also introduced new initiatives to extend support for healthy eating and physical activity. CONCLUSION:Our findings indicate improvements in healthy eating and physical activity, and social connections among program participants, as well as efforts by community organizations to create environments to support healthy weights. HT was successfully delivered in "real-world" community settings across multiple contexts and with families with diverse backgrounds. This along with strategies to support program implementation and sustainability indicate that HT provides a model for other public health interventions to promote family health and wellbeing.
