Dietary Intakes and Physical Activity among Preschool-Aged Children Living in Rural American Indian Communities before a Family-Based Healthy Lifestyle Intervention

OBJECTIVE To report dietary intake and physical activity among preschool-aged children living in rural American Indian communities before participation in a family-based healthy lifestyle intervention and to compare data to current age-specific recommendations. SUBJECTS/DESIGN One hundred thirty-five preschool-aged children, living in rural American Indian communities, provided diet and physical activity data before participating in a 2-year randomized healthy lifestyle intervention. Three 24-hour dietary recalls assessed nutrient and food and added sugar intake, which were compared to the National Academy of Sciences Dietary Reference Intakes, the US Department of Agricultures MyPyramid, and American Heart Association recommendations. Time watching television and moderate plus vigorous activity was compared to MyPyramid and American Academy of Pediatrics recommendations. STATISTICAL ANALYSIS Nutrient, food group, added sugar intake, and time watching television and in moderate or vigorous activity were compared to recommendations by computing the percent of recommendations met. Nonparametric tests identified differences in diet and physical activity among age groups and normal and overweight children (body mass index <85th and > or = 85th percentile). RESULTS Average nutrient intakes met recommendations whereas food group intakes did not. Mean fruit and vegetable intakes for 2- to 3-year-olds were 0.36 c/day fruit and 0.45 c/day vegetables and, for 4- to 5-year-olds, 0.33 c/day fruit and 0.48 c/day vegetables. Both age groups reported consuming more than 50 g added sugar, exceeding the recommendation of 16 g. Overweight vs normal weight children reported significantly more sweetened beverage intake (8.0+/-0.10 vs 5.28+/-0.08 oz/day, P<0.01). On average, all children reported watching television 2.0 hours/day and significant differences were observed for total television viewing and nonviewing time between overweight and normal weight children (8.52+/-0.6 vs 6.54+/-0.6 hours/day, P<0.01). All children engaged in <20 minutes/day of moderate or vigorous activity. CONCLUSIONS Overall, children in this sample did not meet MyPyramid recommendations for fruits or vegetables and exceed added sugar intake recommendations. Television viewing time and time when the television was on in the home was highly prevalent along with low levels of moderate or vigorous activity. The Healthy Children Strong Families intervention we studied has potential for improving nutrition and physical activity among preschool-aged children living in rural American Indian communities.

Correlates of physical activity in young American Indian children: lessons learned from the Wisconsin Nutrition and Growth Study.

BACKGROUND Obesity is a serious and growing health problem in American Indian (AI) children. Our study, the Wisconsin Nutrition and Growth Study, aimed to understand the prevalence and contributing factors to pediatric obesity in Wisconsin tribes and provide the foundation for intervention design. OBJECTIVE This article focuses on associations among age, gender, and 3 measures of weight status with proxy-reported physical activity and TV/screen time in 3 to 8 year-old AI children. DESIGN/METHODS In a cross-sectional design, 581 AI children (49.1% female, aged 3-8 years) participated in health screenings that included height, weight, waist circumference, percent body fat, and a caregiver survey on demographics and health, with questions on physical activity and TV/screen time. RESULTS Forty-five percent of children were overweight or obese. Boys were significantly more obese and had higher levels of body fat than girls. There were no differences in weight category across age groups. Boys participated in significantly more weekly sports than girls and sports participation was somewhat higher in younger children. Body mass index and waist circumference were not significantly correlated with TV/screen time or with the 3 activity measures (sports participation, outdoor play time, or physical education classes). Hours of outdoor play significantly predicted child body fat percentage controlling for maternal body mass index and child age and gender. CONCLUSIONS Young AI children in Wisconsin have high rates of overweight/obesity starting at a very early age, and outdoor play may play a significant role in mediating body fat. There is a need to develop obesity-prevention interventions at early ages.

The Healthy Children, Strong Families intervention promotes improvements in nutrition, activity and body weight in American Indian families with young children

Objective American Indian children of pre-school age have disproportionally high obesity rates and consequent risk for related diseases. Healthy Children, Strong Families was a family-based randomized trial assessing the efficacy of an obesity prevention toolkit delivered by a mentor v. mailed delivery that was designed and administered using community-based participatory research approaches. Design During Year 1, twelve healthy behaviour toolkit lessons were delivered by either a community-based home mentor or monthly mailings. Primary outcomes were child BMI percentile, child BMI Z-score and adult BMI. Secondary outcomes included fruit/vegetable consumption, sugar consumption, television watching, physical activity, adult health-related self-efficacy and perceived health status. During a maintenance year, home-mentored families had access to monthly support groups and all families received monthly newsletters. Setting Family homes in four tribal communities, Wisconsin, USA. Subjects Adult and child (2–5-year-olds) dyads (n 150). Results No significant effect of the mentored v. mailed intervention delivery was found; however, significant improvements were noted in both groups exposed to the toolkit. Obese child participants showed a reduction in BMI percentile at Year 1 that continued through Year 2 (P<0·05); no change in adult BMI was observed. Child fruit/vegetable consumption increased (P=0·006) and mean television watching decreased for children (P=0·05) and adults (P=0·002). Reported adult self-efficacy for health-related behaviour changes (P=0·006) and quality of life increased (P=0·02). Conclusions Although no effect of delivery method was demonstrated, toolkit exposure positively affected adult and child health. The intervention was well received by community partners; a more comprehensive intervention is currently underway based on these findings.

Healthy Children, Strong Families 2: A randomized controlled trial of a healthy lifestyle intervention for American Indian families designed using community-based approaches:

Background/Aims Few obesity prevention trials have focused on young children and their families in the home environment, particularly in underserved communities. Healthy Children, Strong Families 2 is a randomized controlled trial of a healthy lifestyle intervention for American Indian children and their families, a group at very high risk of obesity. The study design resulted from our long-standing engagement with American Indian communities, and few collaborations of this type resulting in the development and implementation of a randomized clinical trial have been described. Methods Healthy Children, Strong Families 2 is a lifestyle intervention targeting increased fruit and vegetable intake, decreased sugar intake, increased physical activity, decreased TV/screen time, and two less-studied risk factors: stress and sleep. Families with young children from five American Indian communities nationwide were randomly assigned to a healthy lifestyle intervention (Wellness Journey) augmented with social support (Facebook and text messaging) or a child safety control group (Safety Journey) for 1 year. After Year 1, families in the Safety Journey receive the Wellness Journey, and families in the Wellness Journey start the Safety Journey with continued wellness-focused social support based on communities’ request that all families receive the intervention. Primary (adult body mass index and child body mass index z-score) and secondary (health behaviors) outcomes are assessed after Year 1 with additional analyses planned after Year 2. Results To date, 450 adult/child dyads have been enrolled (100% target enrollment). Statistical analyses await trial completion in 2017. Lessons learned Conducting a community-partnered randomized controlled trial requires significant formative work, relationship building, and ongoing flexibility. At the communities’ request, the study involved minimal exclusion criteria, focused on wellness rather than obesity, and included an active control group and a design allowing all families to receive the intervention. This collective effort took additional time but was critical to secure community engagement. Hiring and retaining qualified local site coordinators was a challenge but was strongly related to successful recruitment and retention of study families. Local infrastructure has also been critical to project success. Other challenges included geographic dispersion of study communities and providing appropriate incentives to retain families in a 2-year study. Conclusion This multisite intervention addresses key gaps regarding family/home-based approaches for obesity prevention in American Indian communities. Healthy Children, Strong Families 2’s innovative aspects include substantial community input, inclusion of both traditional (diet/activity) and less-studied obesity risk factors (stress/sleep), measurement of both adult and child outcomes, social networking support for geographically dispersed households, and a community selected active control group. Our data will address a literature gap regarding multiple risk factors and their relationship to health outcomes in American Indian families.

Does Micropractice Lead to Macrosatisfaction

Background: Physician quality of work life is a key factor in career choice, satisfaction, and retention. The majority of physicians are currently employed by large health care organizations where physician loss of autonomy is common, yet some physicians have opened micropractices. There have been no previous studies comparing physician satisfaction between employed physicians and micropractice physicians. Methods: A previously validated survey of physician satisfaction was sent to 72 physicians practicing in a residency setting, 111 physicians in community, nonresidency setting, and 42 physicians in a micropractice setting. Results: Physicians in micropractices had the lowest satisfaction with income, but the highest satisfaction with family time and the ability to provide continuity of care. Micropractice physicians rated the overall quality of medical care they provide higher than employed physicians. Micropractice physicians reported a much smaller scope of practice. Conclusions: Overall, physicians in micropractices found more satisfaction in their work at the cost of decreased income and a narrower scope of practice.

Sleep has emerged as a potentially modifiable risk factor for obesity in children.

Understanding Correlates of Physical Activity in American Indian Families: The Healthy Children Strong Families-2 Study

BACKGROUND Little is known about factors contributing to physical activity (PA) in American Indian (AI) populations. Addressing this gap is paramount as sedentary activity and obesity continue to increase in this population. The purpose of this study was to determine factors associated with PA among AI families with young children. METHODS Height and weight of both adult (n = 423) and child (n = 390) were measured, and surveys assessed demographics, PA, stress (adult only), sleep, and screen time. Separate multivariate logistic regression models were constructed for adults and children (reported as adjusted odds ratios, aORs). RESULTS For adults, age (aOR = 0.952; P ≤ .001), television viewing (aOR = 0.997; P = .01), and computer use (aOR = 0.996; P = .003) decreased the odds of being active. For children, high adult activity (aOR = 1.795; P ≤ .01), longer weekday sleep (aOR = 1.004; P = .01), and family income >

Predictors of Overweight and Obesity in American Indian Families With Young Children

35,000 (aOR = 2.772; P = .01) increased the odds of being active. We found no association between adult PA with stress or adult sleep or between child PA with body mass index and screen time. CONCLUSIONS Given the complexity of the factors contributing to obesity among AI families, multigenerational interventions focused on healthy lifestyle change such as decreasing adult screen time and increasing child sleep time may be needed to increase PA within AI families.

Evaluation of a multi-year policy-focused intervention to increase physical activity and related behaviors in lower-resourced early care and education settings: Active Early 2.0

Objective: To describe sociodemographic factors and health behaviors among American Indian (AI) families with young children and determine predictors of adult and child weight status among these factors. Design: Descriptive, cross‐sectional baseline data. Setting: One urban area and 4 rural AI reservations nationwide. Participants: A total of 450 AI families with children aged 2–5 years participating in the Healthy Children, Strong Families 2 intervention. Intervention: Baseline data from a healthy lifestyles intervention. Main Outcome Measures: Child body mass index (BMI) z‐score and adult BMI, and multiple healthy lifestyle outcomes. Analysis: Descriptive statistics and stepwise regression. Results: Adult and child combined overweight and obesity rates were high: 82% and 40%, respectively. Food insecurity was high (61%). Multiple lifestyle behaviors, including fruit and vegetable and sugar‐sweetened beverage consumption, adult physical activity, and child screen time, did not meet national recommendations. Adult sleep was adequate but children had low overnight sleep duration of 10 h/d. Significant predictors of child obesity included more adults in the household (P = .003; &bgr; = 0.153), an adult AI caregiver (P = .02; &bgr; = 0.116), high adult BMI (P = .001; &bgr; = 0.176), gestational diabetes, high child birth weight (P < .001; &bgr; = 0.247), and the family activity and nutrition score (P = .04; &bgr; = 0.130). Conclusions and Implications: We found multiple child‐, adult‐, and household‐level factors influence early childhood obesity in AI children, highlighting the need for interventions to mitigate the modifiable factors identified in this study, including early life influences, home environments, and health behaviors.

Low Recognition of Childhood Overweight and Disease Risk among Native-American Caregivers

Physical activity is a critical component of obesity prevention, but few interventions targeting early childhood have been described. The Active Early guide was designed to increase physical activity in early care and education (ECE) settings. The purpose of Active Early 2.0 was to evaluate the effectiveness of Active Early along with provider training, microgrant support, and technical assistance over 2 years (2012–2014) to increase physical activity and related behaviors (e.g., nutrition) in settings serving a high proportion of children from underserved groups in recognition of significant disparities in obesity and challenges meeting physical activity recommendations in low-resource settings. The physical activity and nutrition environment were assessed before and after the intervention in 15 ECE settings in Wisconsin using the Environment and Policy Observation Assessment tool, and interviews were conducted with providers and technical consultants. There was no significant change in Total Physical Activity Score or any EPAO subscale over the intervention period; however, significant improvements in the Total Nutrition Score and the several Nutrition subscales were observed. Additionally, the percentage of sites with written activity policies significantly increased. Overall minutes of teacher-led physical activity increased to 61.5 ± 29.0 min (p < 0.05). Interviews identified key benefits to children (i.e., more energy, better rest, improved behavior) and significant barriers, most notably care provider and child turnover and low parent engagement. Moderate policy and environmental improvements in physical activity and nutrition were achieved with this intervention, but more work is needed to understand and address barriers and to support sustained changes in lower-resource ECE settings.
