Changes in High Weight-for-Length among Infants Enrolled in Special Supplemental Nutrition Program for Women, Infants, and Children during 2010-2018.

Background: Infants and young children with high weight-for-length are at increased risk for obesity in later life. This study describes prevalence of high weight-for-length and examines changes during 2010-2018 among 11,366,755 infants and young children 3-23 months of age in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Methods: Children's weights and lengths were measured. High weight-for-length was defined as ≥2 standard deviations above sex and age-specific median on World Health Organization growth charts. Adjusted prevalence differences (APDs) between years were calculated as 100 times marginal effects from logistic regression models. APD was statistically significant if 95% confidence interval did not include 0. Results: Adjusted prevalence of high weight-for-length decreased from 2010 to 2014, and leveled off through 2018 overall, in boys and girls, those 6-11 and 18-23 months of age, and non-Hispanic whites, non-Hispanic blacks, Hispanics, and Asians/Pacific Islanders. For 12-17 months old and American Indian/Alaska Native infants and young children, adjusted prevalence decreased from 2010 to 2014, and then increased slightly through 2018. Among 56 WIC state or territorial agencies, 33 had significant decreases between 2010 and 2018, whereas 8 had significant increases. Between 2014 and 2018, prevalence decreased significantly in 12 agencies and increased significantly in 23. Conclusions: The results indicate overall declines in prevalence of high weight-for-length from 2010 to 2018, with a prevalence stabilization since 2014. Continued surveillance is needed. Obesity prevention strategies in WIC and multiple settings are important for ensuring healthy child growth.

State-Specific Prevalence of Obesity Among Children Aged 2-4 Years Enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children - United States, 2010-2016.

Obesity negatively affects children's health because of its associations with cardiovascular disease risk factors, type 2 diabetes, asthma, fatty liver disease, victimization stemming from social stigma and bullying, and poor mental health (e.g., anxiety and depression) (1). Children who have overweight or obesity in early childhood are approximately four times as likely to have overweight or obesity in young adulthood as their normal weight peers (2). Obesity prevalence is especially high among children from low-income families (3). In 2010, the overall upward trend in obesity prevalence turned downward among children aged 2-4 years enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), a program of the U.S. Department of Agriculture (USDA); prevalence decreased significantly in all racial/ethnic groups and in 34 of the 56 WIC state or territory agencies during 2010-2014 (4). A more recent study among young children enrolled in WIC reported that the overall obesity prevalence decreased from 15.9% in 2010 to 13.9% in 2016 and statistically significant decreases were observed in all age, sex, and racial/ethnic subgroups (3). However, this study did not provide obesity trends at the state level. In collaboration with USDA, CDC used data from the WIC Participant and Program Characteristics (WIC PC) to update state-specific trends through 2016. During 2010-2016, modest but statistically significant decreases in obesity prevalence among children aged 2-4 years enrolled in WIC occurred in 41 (73%) of 56 WIC state or territory agencies. Comprehensive approaches that create positive changes to promote healthy eating and physical activity for young children from all income levels,* strengthen nutrition education and breastfeeding support among young children enrolled in WIC, and encourage redemptions of healthy foods in WIC food packages could help maintain or accelerate these declining trends.

Local government retail incentives for healthier food retailers in the USA, 2014.

OBJECTIVE: National public health organizations recommend that local governments improve access to healthy foods. One way is by offering incentives for food retailer development and operation, but little is known about incentive use nationwide. We aimed to describe the national prevalence of local government reported incentives to increase access to healthy food options in three major food retail settings (farmers' markets, supermarkets, and convenience or corner (smaller) stores) overall and by municipality characteristics. DESIGN: Cross-sectional study using data from the 2014 National Survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living. SETTING: USA, nationally representative survey of 2029 municipalities. PARTICIPANTS: Municipal officials (e.g. city/town managers or planners; n 1853). RESULTS: Overall, 67 % of municipalities reported incentives to support farmers' markets, 34 % reported incentives to encourage opening new supermarkets, and 14 % reported incentives to help existing convenience or corner stores. Municipality characteristics significantly associated with incentive use were larger population size (all settings), location in Midwest v. West (supermarkets, smaller stores), higher poverty level (farmers' markets) and ≤50 % of the population non-Hispanic White (supermarkets, smaller stores). The most commonly reported individual incentives were permission of sales on city property for farmers' markets, tax credits for supermarkets and linkage to revitalization projects for smaller stores. CONCLUSIONS: Most municipalities offered food retail incentives for farmers' markets, but fewer used incentives to open new supermarkets or assist existing smaller stores. National data can set benchmarks, provide relative comparisons for communities and identify areas for improvement.

Supporting Active Living Through Community Plans: The Association of Planning Documents With Design Standards and Features.

PURPOSE: The purpose of this study was to examine the association between the presence of supportive community planning documents in US municipalities with design standards and requirements supportive of active living. DESIGN: Cross-sectional study using data from the 2014 National Survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living. SETTING: Nationally representative sample of US municipalities. PARTICIPANTS: Respondents are 2005 local officials. MEASURES: Assessed: (1) The presence of design standards and feature requirements and (2) the association between planning documents and design standards and feature requirements supportive of active living in policies for development. ANALYSIS: Using logistic regression, significant trends were identified in the presence of design standards and feature requirements by plan and number of supportive objectives present. RESULTS: Prevalence of design standards ranged from 19% (developer dedicated right-of-way for bicycle infrastructure development) to 50% (traffic-calming features in areas with high pedestrian and bicycle volume). Features required in policies for development ranged from 14% (short/medium pedestrian-scale block sizes) to 44% (minimum sidewalk widths of 5 feet) of municipalities. As the number of objectives in municipal plans increased, there was a significant and positive trend ( P < .05) in the prevalence of each design standard and requirement. CONCLUSIONS: Municipal planning documents containing objectives supportive of physical activity are associated with design standards and feature requirements supportive of activity-friendly communities.

Developmental Process and Early Phases of Implementation for the US Interagency Committee on Human Nutrition Research National Nutrition Research Roadmap 2016-2021.

The Interagency Committee on Human Nutrition Research (ICHNR) is charged with improving the planning, coordination, and communication among federal agencies engaged in nutrition research and with facilitating the development and updating of plans for federal research programs to meet current and future domestic and international needs for nutrition. The ICHNR is co-chaired by the USDA Under Secretary for Research, Education, and Economics and Chief Scientist and the US Department of Health and Human Services Assistant Secretary for Health and is made up of >10 departments and agencies. Once the ICHNR was reassembled after a 10-y hiatus, the ICHNR recognized a need for a written roadmap to identify critical human nutrition research gaps and opportunities. This commentary provides an overview of the process the ICHNR undertook to develop a first-of-its-kind National Nutrition Research Roadmap, which was publicly released on 4 March 2016. The primary audience for the Roadmap is federal science agency leaders, along with relevant program and policy staff who rely on federally supported human nutrition research, in addition to the broader scientific community. The Roadmap is framed around the following 3 questions: 1) How can we better understand and define eating patterns to improve and sustain health? 2) What can be done to help people choose healthy eating patterns? 3) How can we develop and engage innovative methods and systems to accelerate discoveries in human nutrition? Within these 3 questions, 11 topical areas were identified on the basis of the following criteria: population impact, feasibility given current technological capacities, and emerging scientific opportunities. This commentary highlights initial federal and some professional research society efforts to address the Roadmap's research and resource priorities. We conclude by noting examples of early collaborations and partnerships to move human nutrition research forward in the 21st century.

Sociodemographic and Behavioral Factors Associated with Added Sugars Intake among US Adults.

BACKGROUND: Reducing added sugars intake is one of the Healthy People 2020 objectives. High added sugars intake may be associated with adverse health consequences. OBJECTIVE: This cross-sectional study identified sociodemographic and behavioral characteristics associated with added sugars intake among US adults (18 years and older) using the 2010 National Health Interview Survey data (n=24,967). METHODS: The outcome variable was added sugars intake from foods and beverages using scoring algorithms to convert dietary screener frequency responses on nine items to estimates of individual dietary intake of added sugars in teaspoons per day. Added sugars intake was categorized into tertiles (lowest, middle, highest) stratified by sex. The explanatory variables were sociodemographic and behavioral characteristics. Multinomial logistic regression was used to estimate the adjusted odds ratios for the highest and middle tertile added sugars intake groups as compared with the lowest tertile group. RESULTS: Estimated median added sugars intake was 17.6 tsp/d for men and 11.7 tsp/d for women. For men and women, those who had significantly greater odds for being in the highest tertile of added sugars intake (men: ≥22.0 tsp/d; women: ≥14.6 tsp/d) were younger, less educated, had lower income, were less physically active, were current smokers, and were former or current infrequent/light drinkers, whereas non-Hispanic other/multiracial and those living in the West had significantly lower odds for being in the highest tertile of added sugars intake. Different patterns were found by sex. Non-Hispanic black men had lower odds for being in the highest tertile of added sugars intake, whereas non-Hispanic black women had greater odds for being in the highest tertile. CONCLUSIONS: One in three men consumed ≥22.0 tsp added sugars and one in three women consumed ≥14.6 tsp added sugars daily. Higher added sugars intake was associated with various sociodemographic and behavioral characteristics; this information can inform efforts to design programs and policies specific to high-intake populations.

Regional Differences in Sugar-Sweetened Beverage Intake among US Adults.

BACKGROUND: Higher consumption of sugar-sweetened beverages (SSBs) is associated with obesity and type 2 diabetes, and the prevalence of obesity varies by geographic region. Although information on whether SSB intake differs geographically could be valuable for designing targeted interventions, this information is limited. OBJECTIVE: This cross-sectional study examined associations between living in specific census regions and frequency of SSB consumption among US adults using 2010 National Health Interview Survey data (n=25,431). METHODS: SSB consumption was defined as the consumption of four types of beverages (regular sugar-sweetened carbonated beverages, fruit drinks, sports/energy drinks, and sweetened coffee/tea drinks). The exposure variable was census region of residence (Northeast, Midwest, South, and West). We used multivariable logistic regression to estimate adjusted odds ratios (aORs) and 95% CIs for drinking SSBs after controlling for sociodemographic characteristics. RESULTS: Approximately 64% of adults consumed SSBs ≥1 time/day. The odds of drinking SSBs ≥1 time/day were significantly higher among adults living in the Northeast (aOR=1.13; 95% CI=1.01, 1.26) but lower among adults living in the Midwest (aOR=0.70; 95% CI=0.64, 0.78) or West (aOR=0.78; 95% CI=0.71, 0.87) compared with those living in the South. By type of SSB, the odds of drinking regular soda ≥1 time/day was significantly lower among adults living in the Northeast (aOR=0.51; 95% CI=0.45, 0.57), Midwest (aOR=0.86; 95% CI=0.78, 0.96), or West (aOR=0.56; 95% CI=0.51, 0.62) than those living in the South. The odds of drinking sports/energy drinks ≥1 time/day were significantly lower among adults living in the West (aOR=0.77; 95% CI=0.64, 0.93) than those living in the South. The odds of drinking a sweetened coffee/tea drink ≥1 time/day were significantly higher among adults living in the Northeast (aOR=1.60; 95% CI=1.43, 1.78) but lower among adults living in the Midwest (aOR=0.70; 95% CI=0.62, 0.78) than those living in the South. CONCLUSIONS: Total frequency of SSB consumption and types of SSB consumption differed by geographic region. Interventions to reduce SSB intake could consider regional variations in SSB intake, particularly when more local data are not available.

Variation in delivery of the 10 essential public health services by local health departments for obesity control in 2005 and 2008.

OBJECTIVES: To describe and compare the capacity of local health departments (LHDs) to perform 10 essential public health services (EPHS) for obesity control in 2005 and 2008, and explore factors associated with provision of these services. METHODS: The data for this study were drawn from the 2005 and 2008 National Profile of Local Health Department surveys, conducted by the National Association of County and City Health Officials. Data were analyzed in SAS version 9.1 (SAS Institute Inc, Cary, North Carolina). RESULTS: The proportion of LHDs that reported that they do not provide any of the EPHS for obesity control decreased from 27.9% in 2005 to 17.0% in 2008. In both 2005 and 2008, the 2 most frequently provided EPHS for obesity control by LHDs were informing, educating, and empowering the people (EPHS 3) and linking people to needed personal health services (EPHS 7). The 2 least frequently provided services were enforcing laws and regulations (EPHS 6) and conducting research (EPHS 10). On average, LHDs provided 3.05 EPHS in 2005 and 3.69 EPHS in 2008. Multiple logistic regression results show that LHDs with larger jurisdiction population, with a local governance, and those that have completed a community health improvement plan were more likely to provide more of the EPHS for obesity (P < .05). CONCLUSIONS: The provision of the 10 EPHS for obesity control by LHDs remains low. Local health departments need more assistance and resources to expand performance of EPHS for obesity control. Future studies are needed to evaluate and promote LHD capacity to deliver evidence-based strategies for obesity control in local communities.

Knowledge of energy balance guidelines and associated clinical care practices: the U.S. National Survey of Energy Balance Related Care among Primary Care Physicians.

OBJECTIVE: To assess primary care physicians' (PCPs) knowledge of energy balance related guidelines and the association with sociodemographic characteristics and clinical care practices. METHOD: As part of the 2008 U.S. nationally representative National Survey of Energy Balance Related Care among Primary Care Physicians (EB-PCP), 1776 PCPs from four specialties who treated adults (n=1060) or children and adolescents (n=716) completed surveys on sociodemographic information, knowledge of energy balance guidelines, and clinical care practices. RESULTS: EB-PCP response rate was 64.5%. For PCPs treating children, knowledge of guidelines for healthy BMI percentile, physical activity, and fruit and vegetables intake was 36.5%, 27.0%, and 62.9%, respectively. For PCPs treating adults, knowledge of guidelines for overweight, obesity, physical activity, and fruit and vegetables intake was 81.4%, 81.3%, 70.9%, and 63.5%, respectively. Generally, younger, female physicians were more likely to exhibit correct knowledge. Knowledge of weight-related guidelines was associated with assessment of body mass index (BMI) and use of BMI-for-age growth charts. CONCLUSION: Knowledge of energy balance guidelines among PCPs treating children is low, among PCPs treating adults it appeared high for overweight and obesity-related clinical guidelines and moderate for physical activity and diet, and was mostly unrelated to clinical practices among all PCPs.

Cost-effectiveness of osteoporosis screening and treatment with hormone replacement therapy, raloxifene, or alendronate.

Recent information about osteoporosis treatments and their nonfracture side effects suggests the need for a new cost-effectiveness analysis. The authors estimate the cost effectiveness of screening women for osteoporosis at age 65 and treating those who screen positive with hormone replacement therapy (HRT), raloxifene, or alendronate. A Markov model of osteoporosis disease progression simulates costs and outcomes of women aged 65 years. Incremental cost effectiveness ratios of screen-and-treat strategies are calculated relative to a no-screen, no-treat (NST) strategy. Disease progression parameters are derived from clinical trials; cost and quality-of-life parameters are based on review of cost databases and cost-effectiveness studies. Women are screened using dual-energy x-ray absorptiometry, and women screening positive are treated with HRT, raloxifene, or alendronate. Screening and treatment with HRT increase costs and lower quality-adjusted life years (QALYs; relative to the NST strategy). The only scenario (of several) in the sensitivity analysis in which HRT increases QALYs is when it is assumed that there are no drug-related (nonfracture) health effects. Raloxifene increases costs and QALYs; its cost-effectiveness ratio is $447,559 per QALY. When prescribed for the shortest duration modeled, raloxifene's cost-effectiveness ratio approached $133,000 per QALY. Alendronate is the most cost-effective strategy; its cost-effectiveness ratio is $72,877 per QALY. Alendronate's cost-effectiveness ratio approaches $55,000 per QALY when treatment effects last for 5 years or the discount rate is set to zero. The authors conclude that screening and treating with alendronate are more cost-effective than screening and treating with raloxifene or HRT. Relative to an NST strategy, alendronate has a fairly good cost-effectiveness ratio.

Walking trends among U.S. adults: the Behavioral Risk Factor Surveillance System, 1987-2000.

OBJECTIVE: To examine trends in walking among adults in 31 states. METHODS: Trends by sociodemographic strata were analyzed from respondents who participated in the Behavioral Risk Factor Surveillance System (BRFSS). RESULTS: The prevalence of walking among men increased 3.8% (95% confidence interval [CI]=2.4-5.2), from 26.2% (95% CI=25.1-25.3) in 1987 to 30.1% (95% CI=29.4-30.8) in 2000. In women, walking increased 6.6% (95% CI=5.4-7.8), from 40.4% (95% CI=-39.4-41.1) to 46.9% (95% CI=46.2-47.6) during the same time period. However, the prevalence of walking three times a week for 30 minutes duration remained constant across all years. The largest increases occurred in minority subpopulations: 8.7% (95% CI=3.2-14.2) in Hispanic women, 8.5% (95% CI=4.4-12.6) non-Hispanic black women, and 7.0% (95% CI=2.3-11.7) in non-Hispanic black men. Walking was the most frequently reported activity among adults who met the national recommendations for regular physical activity (defined as five or more times a week for > or =30 minutes per session). CONCLUSIONS: Given the acceptability of walking across all sociodemographic subgroups, efforts to increase the frequency of walking could markedly increase the percentage of U.S. adults who engage in regular physical activity, a national priority identified in the Healthy People 2010 objectives for the nation.

Trends and correlates of class 3 obesity in the United States from 1990 through 2000.

CONTEXT: Although the prevalence of obesity has markedly increased among US adults, health risks vary according to the severity of obesity. Persons with class 3 obesity (body mass index [BMI] > or = 40) are at greatest risk, but there is little information about this subgroup. OBJECTIVE: To examine correlates of class 3 obesity and secular trends. DESIGN, SETTING, AND PARTICIPANTS: Adults (aged > or = 18 years) in the United States who participated in the Behavioral Risk Factor Surveillance System telephone survey between 1990 (75,600 persons) and 2000 (164,250 persons). MAIN OUTCOME MEASURE: Body mass index calculated from self-reported weight and height. RESULTS: The prevalence of class 3 obesity increased from 0.78% (1990) to 2.2% (2000). In 2000, class 3 obesity was highest among black women (6.0%), persons who had not completed high school (3.4%), and persons who are short. During the 11-year period, the median BMI level increased by 1.2 units and the 95th percentile increased by 3.2 units. CONCLUSION: The prevalence of class 3 obesity is increasing rapidly among adults. Because these extreme BMI levels are associated with the most severe health complications, the incidence of various diseases will increase substantially in the future.
