A Community-Based Intervention to Prevent Obesity Beginning at Birth Among American Indian Children: Study Design and Rationale for the PTOTS Study

Eating and physical activity behaviors associated with adult obesity have early antecedents, yet few studies have focused on obesity prevention interventions targeting very young children. Efforts to prevent obesity beginning at birth seem particularly important in populations at risk for early-onset obesity. National estimates indicate that American Indian (AI) children have higher rates of overweight and obesity than children of other races/ethnicities. The Prevention of Toddler Obesity and Teeth Health Study (PTOTS) is a community-partnered randomized controlled trial designed to prevent obesity beginning at birth in AI children. PTOTS was developed to test the effectiveness of a multi-component intervention designed to: promote breastfeeding, reduce sugar-sweetened beverage consumption, appropriately time the introduction of healthy solid foods, and counsel parents to reduce sedentary lifestyles in their children. A birth cohort of 577 children from five AI tribes is randomized by tribe to either the intervention (three tribes) or the comparison condition (two tribes). The strengths and weaknesses of PTOTS include a focus on a critical growth phase, placement in the community, and intervention at many levels, using a variety of approaches.     

Effectiveness of a Breastfeeding Self-efficacy Intervention: Do Hospital Practices Make a Difference?

Breastfeeding self-efficacy interventions are important for improving breastfeeding outcomes. However, the circumstances that may influence the effectiveness of the interventions are unclear, especially in the context of hospitals with suboptimal infant feeding practices. Thus, we aimed to evaluate the effect of a self-efficacy intervention on breastfeeding self-efficacy and exclusive breastfeeding, and further assessed the difference in its effect by hospital-routine type. In this intervention study with a control group, 781 pregnant women were recruited from 2 “Baby-Friendly”-certified hospitals (BFH) and 2 non-Baby-Friendly Hospitals (nBFH) in Japan, and were allocated to an intervention or control group. Participants in the intervention group were provided with a breastfeeding self-efficacy workbook in their third trimester. The primary outcome was breastfeeding self-efficacy and the secondary outcome was infant feeding status. All analyses were stratified by the type of hospital, BFH or nBFH. In BFHs, the intervention improved both breastfeeding self-efficacy through 4 weeks postpartum (p = 0.037) and the exclusive breastfeeding rate at 4 weeks postpartum (AOR 2.32, 95 % CI 1.01–5.33). In nBFHs, however, no positive effect was observed on breastfeeding self-efficacy (p =? 0.982) or on the exclusive breastfeeding rate at 4 weeks postpartum (AOR 0.97, 95 % CI 0.52–1.81); in nBFHs, supplementation was provided for breastfed infants and the mother and infant were separated in the vast majority of cases. Infant feeding status at 12 weeks was not improved in either hospital type. The intervention improved breastfeeding self-efficacy and exclusive breastfeeding at 4 weeks postpartum only in BFHs. When breastfeeding self-efficacy interventions are implemented, hospital infant feeding practices may need to be optimized beforehand.     

Progress Towards Narrowing Health Disparities: First Steps in Sorting Out Infant Mortality Trend Improvements Among American Indians and Alaska Natives (AI/ANs) in the Pacific Northwest, 1984–1997

Background Most AI/AN infant mortality rates (IMRs) remain higher than white rates. The Northwest Portland Area Indian Health Board (NPAIHB), serving 43 tribes, CDC and the Washington, Oregon, and Idaho health departments investigated AI/AN infant survival. Methods NPAIHB completed linking computerized birth certificate and birth-death files. We used death and birth cohorts, StatXact and SAS to compare 3-state resident, single and multi-year IMRs, basing infant race on mother’s race, regardless of Hispanic origin. We used CDC’s National Infant Mortality Surveillance ICD-9 categories for cause-specific rates. Results From 1984 to 1997, about 2100–2800 AI/AN births occurred annually. From 1984 to 1990, AI/AN IMRs were 1.8–2.4 fold higher than white rates. Then aggregate-year IMRs significantly declined from 16.3 in 1984–1987 to 6.7 in 1994–1997 (P < 0.0001), approaching the 5.6 1994–1997 white rate. In 1998 the AI/AN IMR rate increased to 10.3. AI/AN SIDS and respiratory distress syndrome rates decreased significantly, respectively, from 8.1 in between 1984–1987 to 2.3 in 1994–1996 and from 1.8 in 1984–1987 to 0.3 in 1991–1993, then leveled off. Significant rate declines occurred among most demographic, risk behavior, birthweight, gestational-age, reproductive risk, birth spacing, and labor/delivery sub-groups. Among others, AI/AN residents in Idaho as well as those who received no prenatal care and who had 0–5 month birth spacing experienced no improvements. Conclusions These uncommon rate declines imply multi-factorial improvements among Northwest AI/ANs. Community-level surveillance and interventions before conception through post-partum may further improve health. Collaborative efforts need to be maintained to continue to monitor changes in AI/AN infant health and maternal characteristics.     

Preterm Birth Among American Indian/Alaskan Natives in Washington and Montana: Comparison with Non-Hispanic Whites

Preterm birth is the single most important cause of perinatal mortality in North America. Given that American Indians/Alaskan Natives (AI/ANs) in the United States continue to have adverse birth outcomes, the purpose of this study is to compare the risk of preterm birth among AI/AN mothers to Non-Hispanic White mothers living in Washington and Montana from 2003 to 2009. A population-based retrospective cohort study was conducted examining the association between AI/AN mothers (self-reported) and the risk of preterm birth (gestational age <37 weeks) using birth certificate data from Washington and Montana. All AI/AN singleton lives births (n = 26,648) from residents of Washington and Montana from 2003 to 2009 were identified and included in our study. An identical number of Non-Hispanic White singleton infants (n = 26,648) born to residents of Washington and Montana were randomly selected as a comparison group and logistic regression was used to analyze the data. AI/AN mothers living in Washington and Montana between 2003 and 2009 were 1.34 times (95 % CI 1.25–1.44) as likely to have a preterm birth compared to Non-Hispanic Whites after adjusting for maternal and paternal characteristics as well as pregnancy risk factors. AI/AN mothers residing in Washington and Montana from 2003 to 2009 were at a significantly increased risk of having a preterm birth compared to Non-Hispanic Whites. Identifying etiologic differences in preterm birth experienced by AI/ANs is essential in targeting future interventions.     

Urban American Indian and Alaska Native Youth: Youth Risk Behavior Survey 1997–2003

Objective To examine the prevalence of health risk-behaviors among American Indian/Alaska Native (AI/AN) youth in urban areas. Methods Data from the national Youth Risk Behavior Survey (YRBS) for the years 1997–2003 were used for the analyses (Urban sample = 52,364). The YRBS is a self-report questionnaire administered to a sample of 9th–12th grade students intended to monitor health risk-behaviors. “Urban” is defined as areas within a Metropolitan Statistical Area. Whites are used as the comparison group for the examination of AI/AN estimates. Results Urban AI/AN youth represented 1% of the urban sample (N = 513). The presence of a number of risk-behaviors were at least threefold higher in AI/AN compared to white youth in urban areas, including suicidal behaviors, feeling unsafe at school and needing medical treatment from a fight. Other factors were over twofold higher among AI/AN, including sexual behaviors, illegal drug use, violence at school, and experiences of rape, assault and pregnancy. Conclusions The higher prevalence of health risk-behaviors in urban AI/AN compared to white youth reflects a need for interventions focused on urban AI/AN youth.     

Dietary Intake Changes in Response to a Sugar-Sweetened Beverage Reduction Trial for Various Supplemental Nutrition Assistance Program (SNAP) Eligibility Groups

Objective

To examine dietary intake differences resulting from a sugar-sweetened beverage reduction intervention by 3 Supplemental Nutrition Assistance Program (SNAP) participation groups: SNAP participants (n?=?56), income-eligible nonparticipants (n?=?30), and income-ineligible nonparticipants (n?=?60).

Peer Reviewed: Effect of School District Policy Change on Consumption of Sugar-Sweetened Beverages Among High School Students, Boston, Massachusetts, 2004-2006

Introduction

Consumption of sugar-sweetened beverages has increased among youth in recent decades, accounting for approximately 13% of total calories consumed. The Boston Public Schools passed a policy restricting sale of sugar-sweetened beverages in Boston schools in June 2004. The objective of this study was to determine whether high school students'' consumption of sugar-sweetened beverages declined after this new policy was implemented.

Methods

We conducted a quasi-experimental evaluation by using data on consumption of sugar-sweetened beverages by public high school students who participated in the Boston Youth Survey during February through April 2004 and February through April 2006 (N = 2,033). We compared the observed change with national trends by using data from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Survey (NHANES). Regression methods were adjusted for student demographics.

Results

On average, Boston''s public high school students reported daily consumption of 1.71 servings of sugar-sweetened beverages in 2004 and 1.38 servings in 2006. Regression analyses showed significant declines in consumption of soda (−0.16 servings), other sugar-sweetened beverages (−0.14 servings), and total sugar-sweetened beverages (−0.30 servings) between 2004 and 2006 (P < .001 for all). NHANES indicated no significant nationwide change in adolescents'' consumption of sugar-sweetened beverages between 2003-2004 and 2005-2006.

Discussion

Data from Boston youth indicated significant reductions in consumption of sugar-sweetened beverages, which coincided with a policy change restricting sale of sugar-sweetened beverages in schools. Nationally, no evidence was found for change in consumption of sugar-sweetened beverages among same-aged youth, indicating that implementing policies that restrict the sale of sugar-sweetened beverages in schools may be a promising strategy to reduce adolescents'' intake of unnecessary calories.     

Fathers as Supporters for Improved Exclusive Breastfeeding in Viet Nam

To determine the extent of exclusive breastfeeding practices among mothers of 4 and 6 month old infants whose fathers received breastfeeding education materials and counseling services. A quasi-experimental design was used. At the baseline, 251 and 241 couples were recruited into the intervention and control sites respectively. Fathers in the intervention area received breastfeeding education materials, counseling services at commune health centers and household visits. In the control site, where mothers routinely receive services on antenatal and postpartum care, fathers did not receive any intervention services on promoting breastfeeding. Primary indicators were exclusive breastfeeding at 4 and 6 months. At 6 months of age, based on 24-hour recall, 16.0 % (38/238) of mothers in the intervention group were exclusively breastfeeding their children, compared to 3.9 % (10/230) of those mothers in the control group (p < 0.001). Significant differences were found based on last-week recall (8.8 % in the intervention group vs. 1.3 % in the control group, p < 0.001) and since-birth recall (6.7 % in the intervention group vs. 0.9 % in the control group, p < 0.01). At 4 months of age, based on since birth recall, the breastfeeding proportion was significantly higher in the intervention group than in control group (20.6 % in the intervention group vs. 11.3 % in the control group, p < 0.01). An intervention targeting fathers might be effective in increasing exclusive breastfeeding practices at 4 and 6 months. To improve exclusive breastfeeding, health care staff working in maternal and child health units, should consider integrating fathers with services delivered to mothers and children.     

Ride Safe: A Child Passenger Safety Program for American Indian/Alaska Native Children

Background In American Indian/Alaska Native (AI/AN) communities, child safety seat (CSS) use rates are much lower than in non-native communities. To reduce this disparity, Indian Health Service (IHS) staff developed, pilot-tested, and implemented Ride Safe, which provided education, training, and child safety seats for children aged 3–5 participating in Tribal Head Start Centers. Methods Focus groups, key informant interviews, and technical review guided program development and implementation. Progress reports and child safety seat use observations, conducted at the beginning and end of three program years (Fall 2003 to Spring 2006), assessed program reach and impact. To examine CSS use, we used three multiple logistic regressions, including a conservative intent to treat analysis. Results Ride Safe reached approximately 3,500 children and their families at 14 sites in six states, providing over 1,700 parents/family members with educational activities, 2,916 child safety seats, and child passenger safety (CPS) technician certification training for 78 Tribal staff. Children were 2.5 times (OR = 2.55, p < .01) as likely to be observed in child safety seats comparing Rounds 1 and 2 data, with the most conservative model showing that the odds of being observed restrained were 74% higher (OR = 1.74, p = <.01) after implementation of the program. Conclusions The Ride Safe Program effectively increased child safety seat use in AI/AN communities, however, observed use rates ranging from 30% to 71% remain well below the 2006 all US rate of 93%. Results from CSS educational and distribution/installation programs such as Ride Safe should be considered in light of the need to increase distribution programs and enhance enforcement activities in AI/AN communities, thereby reducing the disparity in AI/AN motor vehicle injuries and death.     

The Role of Children’s Dietary Pattern and Physical Activity in the Association Between Breastfeeding and BMI at Age 5: The GECKO Drenthe Cohort

Objectives

Breastfeeding is protective against childhood obesity, but the role of childhood lifestyle in this association is unclear. We investigated whether physical activity and dietary pattern at age 5 differed between breastfed and non-breastfed children, and how they relate to Body Mass Index (BMI) Z-scores.

Methods

1477 children of the Dutch GECKO Drenthe birth cohort were included. At one month, children were categorized as breastfed (receiving breast milk exclusively or in combination with formula milk) or non-breastfed (receiving formula milk exclusively). At age 5, height and weight were objectively measured, physical activity was measured by ActiGraph GT3x and dietary patterns were assessed with a parent-reported food pattern questionnaire, assessing the consumption frequency of selected food items at seven occasions over the day.

Results

Non-breastfed children had higher BMI Z-scores (0.36?±?0.90 vs. 0.20?±?0.80 SD, p?=?0.002), more frequently consumed sugar-sweetened beverages (25.0?±?10.5 vs. 22.5?±?9.71 times per week, p?<?0.001), and consumed relatively less whole-wheat or brown bread (p?=?0.007). Differences in sugar-sweetened beverage consumption were most pronounced during main meals. Total fruit consumption, sedentary time and moderate-to-vigorous physical activity levels did not differ between the groups. Multivariable adjusted linear regression analyses showed that the differences in BMI-z score between non-breastfed and breastfed children were not explained by the differences in sugar-sweetened beverages or type of bread consumed.

Conclusions

Infant breastfeeding itself is indicative of healthy dietary behaviors in early life, and is also more likely to be followed by a favorable dietary pattern at toddler age. However, the differences in dietary habits between breastfed and non-breastfed children did not explain the difference in BMI Z-score at the age of 5.

     

Effectiveness of Circle of Life,an HIV-Preventive Intervention for American Indian Middle School Youths: A Group Randomized Trial in a Northern Plains Tribe

Objectives. We assessed the effectiveness of Circle of Life (COL), an HIV-preventive intervention developed specifically for American Indian and Alaska Native (AI/AN) middle school youths.Methods. By partnering with a tribal community, we conducted a longitudinal wait-listed group randomized trial with 635 seventh and eighth graders in 13 schools of a Northern Plains tribe. We surveyed participants at baseline, 3 months, and 12 months from 2006 to 2007.Results. COL was found to increase HIV knowledge in the short term, but had no effect on sexual activity compared with those who did not receive it. However, COL was found to be effective for delaying the onset of sexual activity, with the greatest reduction in risk occurring for those receiving COL at early ages.Conclusions. Community partnership was key to successful project design, implementation, and analysis. The project confirmed the importance of the timing of interventions in early adolescence. COL may be a key resource for reducing sexual risk among AI/AN youths.The HIV/AIDS epidemic in American Indian and Alaska Native (AI/AN) persons has received little attention to date. This population, less than 2% of the nation’s total, has yielded relatively small case numbers in national surveillance statistics.1 Yet, more than 25% of AI/AN individuals living with HIV were estimated to be undiagnosed, a level second only to Asians and Pacific Islanders.2 Once diagnosed with AIDS, AI/AN persons have the lowest survival rate at 12, 24, and 36 months compared with all other race groups.1 Moreover, for AI/AN individuals, the epidemic is disproportionately borne by youths, with 23.1% of all HIV diagnoses among this group occurring among those younger than age 25 years.1 Coupled with high levels of sexually transmitted infections (STIs), early age of first sexual activity, and early onset of substance use,3–5 AI/AN youths are vulnerable to HIV. Targeted prevention should begin at early ages.However, few youth-focused HIV preventive interventions exist for the AI/AN population.6–8 None have been rigorously evaluated. We began discussions with our partners in a Northern Plains (NP) tribe about addressing HIV risk in their community. Our partners requested we focus prevention messages on young adolescents using a culturally meaningful HIV risk reduction intervention. Their requests mirrored research on sexual risk-taking among youths: persons initiating sexual intercourse at young ages are at greater risk of an STI9 and becoming pregnant10; report higher levels of sexual risk-taking11; and respond to culturally appropriate prevention content.12 Here, following standard guidelines for clustered randomized trials,13 we present the results of our effort to rigorously evaluate Circle of Life (COL), a theory-based HIV preventive intervention designed especially for AI/AN adolescents.     

Caregiver Reported Oral Health-Related Quality of Life in Young American Indian Children

American Indian/Alaska Native (AI/AN) children experience high rates of dental decay, yet their pediatric oral health-related quality of life (POQL) has not been described. We measured POQL in AI children and compared it in children with reported excellent/very good/good versus fair/poor oral health status (OHS) and assessed association of OHS, child’s age, dental service utilization, and dental insurance on POQL scores. Caregivers of 143 AI (100 %), young (mean age 25.1 months) children reported their POQL score as 4.2 (scale 0–100, lower score indicates better POQL); OHS as excellent (35 %), very good (27 %), good (21 %), fair (14 %), and poor (3 %); and utilization of urgent dental services (12 %). Worse POQL was associated with worse OHS (p = 0.01). After adjustment, worse POQL was associated with increased reported use of urgent dental services (p = 0.004). POQL of young AI children was generally favorable but worsened with increased utilization of urgent dental services.     

Use of Media Technologies by Native American Teens and Young Adults in the Pacific Northwest: Exploring Their Utility for Designing Culturally Appropriate Technology-Based Health Interventions

American Indian and Alaska Native (AI/AN) youth are disproportionally burdened by many common adolescent health issues, including drug and alcohol use, injury and violence, sexually transmitted infections, and teen pregnancy. Media technologies, including the Internet, cell phones, and video games, offer new avenues for reaching adolescents on a wide range of sensitive health topics. While several studies have informed the development of technology-based interventions targeting mainstream youth, no such data have been reported for AI/AN youth. To fill this gap, this study quantified media technology use among 405 AI/AN youth (13-21?years old) living in tribes and urban communities in the Pacific Northwest, and identified patterns in their health information-seeking practices and preferences. Overall, technology use was exceptionally common among survey respondents, mirroring or exceeding national rates. High rates of online health information seeking were also reported: Over 75% of AI/AN youth reported searching online for health information. These data are now being used by the Northwest Portland Area Indian Health Board and NW tribes to design culturally-appropriate, technology-based health interventions targeting AI/AN youth.     

Perceptions, Barriers, and Suggestions for Creation of a Tobacco and Health Website Among American Indian/Alaska Native College Students

Information concerning American Indian/Alaska Native (AI/AN) Internet use and health information needs is dearth. Our research team explored Internet use among AI/AN college students to determine Internet use in relation to health information seeking behaviors. We used a tobacco site example for participants to describe what they desired in a health site designed specifically for AI/AN. Using a community-based participatory research approach, we conducted 14 focus groups with AI/AN college students (N = 108), to better understand their perceptions of and attitudes toward Internet use and health information needs. Daily Internet use was reported across strata yet health topics investigated differed among groups. Participants in all strata desired a health website that was easy to navigate and interactive. Respectful representation of Native culture was a concern, yet no consensus was reached for a multi-tribal audience. Participants felt a website should use caution with cultural depictions due to the possible misinterpretation. Overall, participants agreed that recreational and traditional tobacco use should be differentiated and the variation of traditional use among tribes acknowledged. Data concerning Internet use for health information among AI/AN college students are needed to establish baseline indicators to effectively address disparities.     

Labor Epidural Anesthesia, Obstetric Factors and Breastfeeding Cessation

Breastfeeding benefits both infant and maternal health. Use of epidural anesthesia during labor is increasingly common and may interfere with breastfeeding. Studies analyzing epidural anesthesia’s association with breastfeeding outcomes show mixed results; many have methodological flaws. We analyzed potential associations between epidural anesthesia and overall breast-feeding cessation within 30 days postpartum while adjusting for standard and novel covariates and uniquely accounting for labor induction. A pooled analysis using Kaplan–Meier curves and modified Cox Proportional Hazard models included 772 breastfeeding mothers from upstate New York who had vaginal term births of healthy singleton infants. Subjects were drawn from two cohort studies (recruited postpartum between 2005 and 2008) and included maternal self-report and maternal and infant medical record data. Analyses of potential associations between epidural anesthesia and overall breastfeeding cessation within 1 month included additional covariates and uniquely accounted for labor induction. After adjusting for standard demographics and intrapartum factors, epidural anesthesia significantly predicted breastfeeding cessation (hazard ratio 1.26 [95 % confidence interval 1.10, 1.44], p < 0.01) as did hospital type, maternal age, income, education, planned breastfeeding goal, and breastfeeding confidence. In post hoc analyses stratified by Baby Friendly Hospital (BFH) status, epidural anesthesia significantly predicted breastfeeding cessation (BFH: 1.19 [1.01, 1.41], p < 0.04; non-BFH: 1.65 [1.31, 2.08], p < 0.01). A relationship between epidural anesthesia and breastfeeding was found but is complex and involves institutional, clinical, maternal and infant factors. These findings have implications for clinical care and hospital policies and point to the need for prospective studies.     

Dietary factors associated with metabolic risk score in Finnish children aged 6–8 years: the PANIC study

Purpose

Previous evidence for the associations of eating frequency and food consumption with clustering of metabolic risk factors among children is limited. We therefore investigated association of the daily number of main meals and snacks and food consumption with a metabolic risk score and individual metabolic risk factors in primary school children.

Methods

The subjects were a population sample of Finnish girls and boys 6–8 years of age. Dietary factors were measured by a four-day food record. Metabolic risk score was calculated summing up the Z-scores of waist circumference, systolic and diastolic blood pressure, and concentrations of fasting serum insulin and fasting plasma glucose, triglycerides and high-density lipoprotein cholesterol, the latest multiplying by ?1.

Results

Skipping main meals (standardized regression coefficient β = ?0.18, P < 0.001), a higher consumption of non-root vegetables (β = 0.18, P < 0.01), low-fat vegetable-oil-based margarine (β = 0.13, P < 0.01) and sugar-sweetened beverages (β = 0.11, P < 0.05) and a lower consumption of vegetable oils (β = ?0.10, P < 0.05) were associated with a higher metabolic risk score after adjustment for age, sex, total physical activity, electronic media time, energy intake and other dietary factors. The consumption of red meat was directly related to the metabolic risk score, but the association was not statistically significant after adjustment for energy intake.

Conclusions

Eating main meals regularly, decreasing the consumption of sugar-sweetened beverages and low-fat margarine and increasing the consumption of vegetable oils should be emphasized to reduce metabolic risk among children.     

Correlates of Overweight and Obesity Among American Indian/Alaska Native and Non-Hispanic White Children and Adolescents: National Survey of Children’s Health, 2007

Risk factors for overweight and obesity may be different for American Indian and Alaska Native (AI/AN) children compared to children of other racial/ethnic backgrounds, as obesity prevalence among AI/AN children remains much higher. Using data from the 2007 National Survey of Children’s Health, behavioral (child’s sport team participation, vigorous physical activity, television viewing, and computer use), household (parental physical activity, frequency of family meals, rules limiting television viewing, and television in the child’s bedroom), neighborhood (neighborhood support, perceived community and school safety, and presence of parks, sidewalks, and recreation centers in the neighborhood), and sociodemographic (child’s age and sex, household structure, and poverty status) correlates of overweight/obesity (body mass index ≥85th percentile for age and sex) were assessed among 10–17 year-old non-Hispanic white (NHW) and AI/AN children residing in Alaska, Arizona, Montana, New Mexico, North Dakota, Oklahoma, and South Dakota (n = 5,372). Prevalence of overweight/obesity was 29.0 % among NHW children and 48.3 % among AI/AN children in this sample. Viewing more than 2 h of television per day (adjusted odds ratio [aOR] = 2.0; 95 % confidence interval [CI] = 1.5–2.8), a lack of neighborhood support (aOR = 1.9; 95 % CI = 1.1–3.5), and demographic characteristics were significantly associated with overweight/obesity in the pooled sample. Lack of sport team participation was significantly associated with overweight/obesity only among AI/AN children (aOR = 2.7; 95 % CI = 1.3–5.2). Culturally sensitive interventions targeting individual predictors, such as sports team participation and television viewing, in conjunction with neighborhood-level factors, may be effective in addressing childhood overweight/obesity among AI/AN children. Longitudinal studies are needed to confirm these findings.     

From Policy to Practice: Addressing Snack Quality,Consumption, and Price in After-School Programs

ObjectiveTo evaluate a community partnership between after-school programs (ASPs) and grocery stores to provide discounted pricing on snacks to meet the National Afterschool Association Healthy Eating Standards that call for serving a fruit or vegetable (FV) daily while eliminating sugar-based foods and beverages.MethodsA single-group, pretest with multiple posttest design (spring, 2011–2013) in 4 large-scale ASPs serving 500 children/d was used, along with direct observation of snacks served, consumed, and cost.ResultsAt baseline, FV, sugar-sweetened beverages, and desserts were served 0.1 ± 0.5, 1.7 ± 2.0, and 2.0 ± 1.4 d/wk. By spring, 2013, FV increased to 5.0 ± 0.0 d/wk, whereas sugar-sweetened beverages and desserts were eliminated. A total of 84% of children consumed the fruit; 59% consumed the vegetables. Cost associated with purchasing snacks resulted in a $2,000–$3,000 savings over a standard 180-day school year.Conclusions and ImplicationsThis partnership can serve as a model for successfully meeting nutrition policies established for ASP snacks.     

The Word Outside and the Pictures in Our Heads: Contingent Framing Effects of Labels on Health Policy Preferences by Political Ideology

This study uses data from systematic Web image search results and two randomized survey experiments to analyze how frames commonly used in public debates about health issues, operationalized here as alternative word choices, influence public support for health policy reforms. In Study 1, analyses of Bing (N = 1,719), Google (N = 1,872), and Yahoo Images (N = 1,657) search results suggest that the images returned from the search query “sugar-sweetened beverage” are more likely to evoke health-related concepts than images returned from a search query about “soda.” In contrast, “soda” search queries were more likely to incorporate brand-related concepts than “sugar-sweetened beverage” search queries. In Study 2, participants (N = 206) in a controlled Web experiment rated their support for policies to reduce consumption of these drinks. As expected, strong liberals had more support for policies designed to reduce the consumption of these drinks when the policies referenced “soda” compared to “sugar-sweetened beverage.” To the contrary, items describing these drinks as “soda” produced lower policy support than items describing them as “sugar-sweetened beverage” among strong conservatives. In Study 3, participants (N = 1,000) in a national telephone survey experiment rated their support for a similar set of policies. Results conceptually replicated the previous Web-based experiment, such that strong liberals reported greater support for a penny-per-ounce taxation when labeled “soda” versus “sugar-sweetened beverages.” In both Studies 2 and 3, more respondents referred to brand-related concepts in response to questions about “sugar-sweetened beverages” compared to “soda.” We conclude with a discussion of theoretical and methodological implications for studying framing effects of labels.     

Breastfeeding rates and duration in Germany: a Bavarian cohort study

Breastfeeding is the recommended feeding for all healthy infants. The aim of our study was to assess the current state of breastfeeding prevalence, duration and behaviour in Bavaria, Germany as a basis for targeting breastfeeding promotion measures. The Bavarian Breastfeeding Study is a prospective cohort study of 3822 mothers who delivered in April 2005 in Bavaria, Germany. Breastfeeding duration and determinants such as socioeconomic status, attitudes towards breastfeeding, birth mode and breastfeeding problems were assessed by questionnaires 2-6 d after birth and 2, 4, 6, and 9 months after birth. The initial breastfeeding rate was 90 %. After 4 months 61 % still breastfed (any breastfeeding). In the multivariate analyses the main influencing factor reducing breastfeeding initiation was the partner's negative attitude towards breastfeeding (OR 21.79; 95 % CI 13.46, 35.27). No initial breastfeeding was also associated with lower education, maternal grandmother's negative attitude and pre-term birth. Protective factors were primary breastfeeding experience and information on breastfeeding before birth. Breastfeeding duration < 4 months was strongly associated with breastfeeding problems (OR 7.56; 95 % CI 6.21, 9.19), smoking, lower education, partner's negative attitude and Caesarean section. Since the attitude of family members is an important influencing factor on breastfeeding rates, breastfeeding promotion should also target the partners of pregnant women and the families of newborn infants. Public health interventions such as more effective support for the management of breastfeeding problems, especially in lower social status families, should be implemented and their effectiveness should be critically evaluated.
