RESUMO
BACKGROUND: Sugar-sweetened beverage (SSB) consumption is an important behavior that can influence individuals' risk for diabetes, obesity, and other chronic diseases. Nonetheless, there is a lack of valid measures to assess SSB-related constructs. Reliable and valid measures can help evaluate the efficacy of interventions designed to curb SSB consumption. Our aim was to develop a valid and reliable instrument to measure constructs related to SSB consumption in English and Spanish. METHODS: A cross-sectional survey was conducted among a convenience sample of 150 adult residents of public housing developments in Boston, Massachusetts between July of 2016 and January of 2017. All households from two public housing developments were approached by study staff to solicit participation via door-to-door knocking and posted flyers. We developed questions to measure three SSB-related constructs informed by the Social Cognitive Theory: SSB knowledge, and self-efficacy and intention to act on SSB consumption. The questions were pilot tested in the population, and then administered in-person by bilingual study staff in either English or Spanish. Interviews were conducted most often in the participant's home and less frequently within a community space. Item normality was assessed with descriptive statistics. Difficulty of knowledge items was assessed with percent correct. Construct validity of self-efficacy items was assessed using confirmatory factor analysis (CFA). A model was considered a good fit if confirmatory factor index (CFI) > 0.95, root mean square error of approximation (RMSEA) < 0.05, and standardized root mean square residual (RMSR) < 0.05. Pearson correlations with consumption scores assessed criterion validity, and intraclass correlation coefficients (ICC) assessed test-retest reliability. RESULTS: Of the eight knowledge items tested, only four items resulted in correct answers less than half of the time. CFA resulted in a 5-item scale with excellent fit indices (CFI = .99; RMSEA = .025: SRMR = .02) and Cronbach's (0.79), test-retest (ICC = 0.68), and significant correlation with intention and SSB consumption. Of the four intention items, one was significantly correlated with SSB consumption. CONCLUSIONS: This study provides evidence for the validity of key constructs related to SSB consumption for use in adults, which could provide important theory-based markers for program evaluations of SSB-related interventions.

Recommendations for the prevention of childhood obesity encourage providers to counsel parents and their children on healthy diet and activity behaviors. This study evaluated the feasibility of a theory-based, tailored communication intervention for obesity prevention (Team Up for Health) delivered during a well-child visit. A two-armed randomized controlled trial was used. Parents of children aged 4-10 years were recruited from a list of patients due for a well-child visit at a pediatric primary care clinic. Parents were randomized to either the 'immediate' condition (parent and pediatrician received the tailored report at the well-child visit) or the 'delayed' condition (parent received the report at the end of the study). Self-report measures assessed physical activity, fruits, vegetables, television time, sugary drinks, and 100% fruit juice. Parents completed assessments at baseline, <48 h and 4-week follow-up. Providers were interviewed at the end of the study. Independent t-tests were used to examine between group differences. Seven areas of feasibility were evaluated: Recruitment, randomization, measurement, retention, acceptability, implementation and demand. Results showed high rates of measurement (85%) and acceptability (89%) and implementation (80%) of the intervention. In conclusion, Team Up for Health was feasible; however, a larger study is needed to evaluate its efficacy.

OBJECTIVE: Research indicates that healthful eating and physical activity (PA) practices implemented in child-care settings can have a positive effect on children's healthful behaviours in this setting, and this effect on healthful behaviours may possibly transfer to the home environment. While more research is needed to examine whether behaviours learned in family child-care homes (FCCH) transfer, the potential for transferability is especially important given that Latino children's home environment has been characterized by obesogenic parenting practices. We aimed to examine Latino parents' perceptions of their pre-school children's eating and PA experiences at home and at FCCH. DESIGN: Qualitative study. Six focus groups were conducted in Spanish (n 36). Transcripts were analysed using thematic analysis to identify key concepts and themes. RESULTS: Analyses revealed that Latino parents perceive their children have healthier eating and PA experiences at FCCH than at home. Parents attributed this to FCCH providers providing an environment conducive to healthful eating and PA due to providers having more knowledge and skills, time and resources, and being required to follow rules and regulations set by the state that promote healthful eating and PA. CONCLUSIONS: Understanding parental perceptions, attitudes and practices related to establishing and maintaining an environment conducive to children's healthful eating and PA at home and at the FCCH is essential for the design of successful interventions to promote children's healthful behaviours in these two settings. Given that parents perceive their children as having more healthful behaviours while at FCCH, interventions that address both settings jointly may be most effective than those addressing only one environment by itself.

BACKGROUND: Reliable, valid and theoretically consistent measures that assess a parent's self-efficacy for helping a child with obesity prevention behaviors are lacking. OBJECTIVES: To develop measures of parental self-efficacy for four behaviors: 1) helping their child get at least 60 minutes of moderate intensity physical activity every day, 2) helping one's child consume five servings of fruits and vegetables each day, 3) limiting sugary drinks to once a week, and 4) limiting consumption of fruit juice to 6 ounces every day. METHODS: Sequential methods of scale development were used. An item pool was generated based on theory and qualitative interviews, and reviewed by content experts. Scales were administered to parents or legal guardians of children 4-10 years old. The item pool was reduced using principal component analysis. Confirmatory factor analysis tested the resulting models in a separate sample. SUBJECTS: 304 parents, majority were women (88%), low-income (61%) and single parents (61%). Ethnic distribution was 40% Black and 37% white. RESULTS: All scales had excellent fit indices: Comparative fit index> .98 and chi-squares (Pediatrics 120 Suppl 4:S229-253, 2007) = .85 - 7.82. Alphas and one-week test-retest ICC's were ≥.80. Significant correlations between self-efficacy scale scores and their corresponding behaviors ranged from .13-.29 (all p < 0.03). CONCLUSIONS: We developed four, four-item self-efficacy scales with excellent psychometric properties and construct validity using diverse samples of parents. CLINICAL TRIAL REGISTRATION: NCT01768533.

Children with attention deficit/hyperactivity disorder (ADHD) struggle with executive functioning (EF). While physical activity (PA) benefits EF, little is known about the impact of specific activities like standing. The purpose of this study was to evaluate the feasibility of performing a rigorous experimental study to compare the effects of walking and standing on EF in children with ADHD. Six areas of feasibility were assessed: recruitment, randomization, treatment adherence, retention, acceptability of the intervention, and implementation. A randomized pilot study using three parallel conditions compared the effects of two modes of activity on EF in children 6-11 with ADHD. While there were no significant differences between walking and standing for EF, analyses suggest that it is feasible to compare effects of standing vs. walking on EF among children with ADHD. This study supports the feasibility of undertaking a larger scale study to evaluate the effect of standing on EF in children with ADHD.
RESUMO
Background: Data suggest that Latinx preschool-age children are at increased risk of obesity. The fastest-growing Latinx population in the United States originates from El Salvador, Guatemala, and Honduras, also known as the Northern Triangle countries. Purpose: To describe how Central American parents from the Northern Triangle countries perceive the importance of energy balance-related behaviors (EBRBs), their preferred sources to obtain information about EBRBs, and to assess whether these differ by parent's gender and country of the nativity. Methods: Cross-sectional survey. Results: Seventy-four parents with at least one child between 2 and 5 years of age participated in the study. More than half were immigrants from El Salvador, Guatemala, and Honduras and were classified as having low acculturation. Mothers perceived consuming >5 fruits and vegetables daily, limiting sugar-sweetened beverages consumption, and having <2â hours daily screen time as extremely important, whereas fathers perceived these behaviors as being less important. Although a higher proportion of foreign-born than US-born parents perceived most of the assessed EBRBs (4 out of 6) as extremely important, these differences were not significant. Parents reported multiple sources to obtain EBRB-related information. Direct person-to-person interactions were the most commonly preferred sources, with pediatricians being the top source (97.3%), followed by other parents (86.5%), and WIC professionals (74.3%). Pediatricians were the preferred source to obtain information about EBRBs, irrespective of parent's gender and country of the nativity. A higher proportion of US-born than foreign-born parents reported a preference to obtain EBRB-related information from other parents. Conclusions: Findings suggest the significance of understanding how Central American parents perceive the importance of EBRBs and the sources they would prefer to obtain information for their children's EBRBs. Study findings have implications for health education and obesity prevention interventions designed to reach and deliver key evidence-based child health information to Central American parents from the Northern Triangle countries in the United States.

BACKGROUND: Hypertension is more prevalent and clinically severe among African-Americans than whites. Several health behaviors influence blood pressure (BP) control, but effective, accessible, culturally sensitive interventions that target multiple behaviors are lacking. PURPOSE: We evaluated a culturally adapted, automated telephone system to help hypertensive, urban African-American adults improve their adherence to their antihypertensive medication regimen and to evidence-based guidelines for dietary behavior and physical activity. METHODS: We randomized 337 hypertensive primary care patients to an 8-month automated, multi-behavior intervention or to an education-only control. Medication adherence, diet, physical activity, and BP were assessed at baseline and every 4 months for 1 year. Data were analyzed using longitudinal modeling. RESULTS: The intervention was associated with improvements in a measure of overall diet quality (+3.5 points, p < 0.03) and in energy expenditure (+80 kcal/day, p < 0.03). A decrease in systolic BP between groups was not statistically significant (-2.3 mmHg, p = 0.25). CONCLUSIONS: Given their convenience, scalability, and ability to deliver tailored messages, automated telecommunications systems can promote self-management of diet and energy balance in urban African-Americans.

BACKGROUND: Health self-management is increasingly being influenced by emerging health information technologies (IT), especially online patient portals. Patient portals provide patients with direct access to their health information, electronic tools to manage their health, and additional opportunities to engage with their care team. Previous studies have found that patient portal use is highest among patients with high eHealth literacy, the ability to find health information from electronic sources and apply the knowledge gained to solve a health problem. The role of eHealth literacy on patient portal use appears to be especially strong among older adults with chronic diseases. The use of patient portals among emerging adults (ages 18-29) is much less understood. Although generally healthy, emerging adults are more regular IT users and just beginning to independently navigate the health care system. A good understanding of how emerging adults are using online patient portals and what factors, including eHealth, impact portal use is lacking. OBJECTIVE: The aim of this study is to describe patient portal use and explore the predictors of portal use among a diverse sample of emerging adults. METHODS: A cross-sectional survey study that used convenience sampling was conducted at two universities. Data on demographics, health care encounters, eHealth literacy, patient engagement, and use of patient portal features (administrative and clinical) were obtained via self-report and summarized. Logistic regression models were used to examine factors associated with portal use. RESULTS: Of the 340 emerging adults, 257 (76%) were female, 223 (65%) White, 156 (47%) low income, and 184 (54%) reported having patient portal access. Of those reporting access, 142 (77%) used at least 1 portal feature and 42 (23%) reported using none. Significant predictors were patient engagement (odds ratio [OR] 1.08, 95% CI 1.04-1.13, P=.001) and total encounters (OR 1.23, 95% CI 1.05-1.44, P=.009) but not eHealth literacy. Hispanic and Asian emerging adults were more likely to be frequent users of clinical portal features than White emerging adults (Hispanic: OR 2.97, 95% CI 1.03-8.52, P=.04; Asian: OR 4.28, 95% CI 1.08-16.89, P=.04). CONCLUSIONS: We found that about half of emerging adults had access to a patient portal. Among those with access, a majority reported using at least one portal feature. Factors associated with increased portal use included increased patient engagement and total clinical encounters. Self-reported eHealth literacy was not associated with patient portal use in this diverse sample of emerging adults. This may have been due to high overall eHealth literacy levels in this population of frequent IT users. There may also be racial/ethnic differences that are important to consider, as we found Hispanic and Asian emerging adults reported more frequent portal use than White emerging adults. Interventions to promote patient portal use among emerging adults should include strategies to increase awareness of portal access and engagement among patients with fewer clinical encounters, with a focus on preventative health management.
RESUMO
BACKGROUND: Research on the influences on bike share use and potential favorable relationships between use and obesity is limited, particularly in the U.S. context. Therefore, the aims of this exploratory study were to examine correlates of awareness and use of Boston's Bluebikes bike share system and assess the association between use and weight status. METHODS: Students, faculty, and staff (n = 256) at a public urban university completed an online survey that assessed sociodemographic, behavioral, and physical activity characteristics, Bluebikes awareness, and use of Bluebikes and personal bikes. Multivariable logistic regression models were estimated to examine associations between sociodemographic and behavioral factors and bike share awareness and use; and between use and overweight/obesity status. RESULTS: Respondents were mostly students (72.2%), female (69.1%), White (62.1%), and the mean age was 32.4±13.8 years. The percentage of respondents classified as aware of Bluebikes was 33.6% with only 12.9% reporting any use of the system. Living in a community where bike share stations were located (odds ratio (OR) = 2.01, 95% confidence interval (CI): 1.10, 3.67), personal bike ownership (OR = 2.27, 95% CI:1.27, 4.45), and not exclusively commuting to campus via car (OR = 3.19, 95% CI:1.63, 6.22) had significant positive associations with awareness. Living in a bike share community (OR = 2.34; 95% CI:1.04, 5.27) and personal bike ownership (OR = 3.09; 95% CI:1.27, 7.52) were positively associated with bike share use. Any reported use of Bluebikes was associated with 60% lower odds of being overweight/obese (OR = 0.40; 95% CI:0.17, 0.93). CONCLUSIONS: Several environmental and behavioral variables, including access to stations and personal bicycle ownership, were significantly associated with Bluebikes awareness and use. Findings also suggest a potential benefit to bike share users in terms of maintaining a healthy weight, though further longitudinal studies are needed to rule out the possibility that more active and leaner individuals tend to use bike share more frequently.

This formative research used a cross-sectional survey to assess interest in informational content and intervention modalities for the design of an early childhood obesity prevention intervention for Central American families from the Northern Triangle countries (El Salvador, Guatemala, and Honduras) living in the United States. A total of 74 parents (36 mothers, 38 fathers) with a mean age of 31.6 years (SD = 5.6) completed the survey; 59.5% of whom were born outside of the United States. Although most parents reported being very interested in receiving information related to the seven assessed energy balance-related behaviors, there were significant differences by parents' gender and nativity. Most parents endorsed remote modalities for content delivery via text/SMS, WhatsApp, and e-mail. However, respondents were also receptive to in-person delivery provided by community health workers. There were also significant differences in parents' preferences for intervention modalities by parents' gender and nativity. Future steps should include investigating different intervention modalities and their integration into a linguistic and culturally sensitive family-based intervention to promote healthful energy balance-related behaviors of preschool-age children in Central American families originating from the Northern Triangle countries.

BACKGROUND: Little is known about disease-specific knowledge in patients with chronic kidney disease (CKD). We developed and examined the results of a survey to characterize kidney disease knowledge. DESIGN: Survey about kidney disease knowledge, with questions developed by experts. SETTING & PARTICIPANTS: 401 adult patients with CKD (stages 1-5) attending a nephrology clinic from April-October 2009. OUTCOMES & MEASUREMENTS: We calculated survey reliability using the Kuder-Richardson-20 coefficient and established construct validity by testing a priori hypotheses of associations between survey results and patient characteristics. We descriptively analyzed survey responses and applied linear regression analyses to evaluate associations with patient characteristics. Health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine. RESULTS: Participants' median age was 58 (25th-75th percentile, 46-68) years, 83% were white, 18% had limited literacy, and 77% had CKD stages 3-5. The 28-question knowledge survey had good reliability (Kuder-Richardson-20 coefficient = 0.72), and mean knowledge score was 66% ± 15% (SD). In support of the construct validity of our knowledge survey, bivariate analysis shows that scores were associated with age (ß = -0.01/10 years; 95% CI, -0.02 to -0.005; P = 0.003), formal education (ß = 0.09; 95% CI, 0.03-0.15; P = 0.004), health literacy (ß = 0.06; 95% CI, 0.03-0.10; P = 0.001), kidney education class participation (ß = 0.05; 95% CI, 0.01-0.09; P = 0.009), knowing someone else with CKD (ß = 0.05; 95% CI, 0.02-0.08; P = 0.001), and awareness of one's own CKD diagnosis (ß = 0.07; 95% CI, 0.04-0.10; P < 0.001). Findings were similar in adjusted analyses. LIMITATIONS: Recruitment from 1 clinic limits generalizability of findings. CONCLUSIONS: For patients with CKD, this Kidney Knowledge Survey (KiKS) is reliable and valid and identifies areas of and risk factors for poor kidney knowledge. Further study is needed to determine the impact of CKD knowledge on self-care behaviors and clinical outcomes.

Despite existing guidelines, dietary sodium intake among people worldwide often exceeds recommended limits. Research evidence is growing in both animal and human studies showing indirect and direct adverse consequences of high dietary sodium on the kidney. In patients with kidney disease, dietary sodium may have important effects on proteinuria, efficacy of antiproteinuric pharmacologic therapy, hypertension control, maintaining an optimal volume status, and immunosuppressant therapy. Dietary sodium intake is an important consideration in patients with all stages of chronic kidney disease, including those receiving dialysis therapy or those who have received a kidney transplant. We review in detail the dietary sodium recommendations suggested by various organizations for patients with kidney disease. Potential barriers to successfully translating current sodium intake guidelines into practice include poor knowledge about the sodium content of food among both patients and providers, complex labeling information, patient preferences related to taste, and limited support for modifications in public policy. Finally, we offer existing and potential solutions that may assist providers in educating and empowering patients to effectively manage their dietary sodium intake.

OBJECTIVES: To develop and evaluate the validity of a scale to assess patients' perceived benefits and risks of reading ambulatory visit notes online (open notes). DESIGN: Four studies were used to evaluate the construct validity of a benefits and risks scale. Study 1 refined the items; study 2 evaluated underlying factor structure and identified the items; study 3 evaluated study 2 results in a separate sample; and study 4 examined factorial invariance of the developed scale across educational subsamples. SETTING: Ambulatory care in three large health systems in the USA. PARTICIPANTS: Participants in three US health systems who responded to one of two online surveys asking about benefits and risks of reading visit notes: a psychometrics survey of primary care patients, and a large general survey of patients across all ambulatory specialties. Sample sizes: n=439 (study 1); n=439 (study 2); n=500 (study 3); and n=250 (study 4). PRIMARY AND SECONDARY OUTCOME MEASURES: Questionnaire items about patients' perceived benefits and risks of reading online visit notes. RESULTS: Study 1 resulted in the selection of a 10-point importance response option format over a 4-point agreement scale. Exploratory factor analysis (EFA) in study 2 resulted in two-factor solution: a four-item benefits factor with good reliability (alpha=0.83) and a three-item risks factor with poor reliability (alpha=0.52). The factor structure was confirmed in study 3, and confirmatory factor analysis of benefit items resulted in an excellent fitting model, X2(2)=2.949; confirmatory factor index=0.998; root mean square error of approximation=0.04 (0.00, 0.142); loadings 0.68-0.86; alpha=0.88. Study 4 supported configural, measurement and structural invariance for the benefits scale across high and low-education patient groups. CONCLUSIONS: The findings suggest that the four-item benefits scale has excellent construct validity and preliminary evidence of generalising across different patient populations. Further scale development is needed to understand perceived risks of reading open notes.

INTRODUCTION: Although resistance training (RT) can lead to acute improvements in psychological, physiological and psychosocial outcomes, prevalence rates remain low in college-age females likely due to perceived barriers. This study compared the effects of an acute bout of both a functional RT (FRT) and traditional RT (TRT) session on affect, state anxiety enjoyment and physiological measures. METHODS: Females (n = 34, mean age = 27 ± 4.5 yr) not currently meeting American College of Sports Medicine RT guidelines completed four sessions (2 FRT, 2 TRT) within 4 wk in a randomized crossover design. Session 1 familiarized participants to the RT exercises. Session 2 consisted of 2 × 10 moderate intensity repetitions. Outcome measures included affect and state anxiety (preexercise, postexercise, and 15 min postexercise); enjoyment (post), and manipulation measures of session RPE and HR). RESULTS: Between-condition comparisons indicate change scores in state anxiety pre- to post-15 (P = 0.028) and enjoyment levels post- (P = 0.02) were significantly greater in FRT than TRT. Within-condition analyses revealed pre- to post-15 changes in affect were positive and greater in FRT (d = 0.79) than TRT (d = 0.53, P = 0.47), and greater in decreases in state anxiety (FRT, d = -0.58; TRT, d = -0.37, P = 0.028). Mean session RPE was not significantly different between conditions (FRT 6 ± 1.2 units; TRT 6.3 ± 1.1 units; P = 0.11), though average percent of age-predicted maximum HR (FRT 68.7 ± 7.6; TRT 57.1 ± 8.4) was significantly different (P < 0.01). CONCLUSIONS: Findings suggest that compared with TRT, FRT is associated with higher acute positive psychological states, higher levels of enjoyment, and greater energy expenditure. Future studies are recommended to examine additional measures of affect and in-task timepoints to determine how these responses relate to maintenance and adherence, thereby potentially increasing the proportion of college females meeting American College of Sports Medicine RT and moderate-to-vigorous physical activity guidelines.

OBJECTIVE: Latinos are the largest and most rapidly growing minority population group in the USA and are disproportionally affected by obesity and related chronic diseases. Child care providers likely influence the eating and physical activity behaviours of children in their care, and therefore are important targets for interventions designed to prevent childhood obesity. Nonetheless, there is a paucity of research examining the behaviours of family child care home (FCCH) providers and whether they model healthy eating and physical activity behaviours. Therefore, this study explored Latino FCCH providers' beliefs and practices related to healthy eating, physical activity and sedentary behaviours, and how they view their ability to serve as role models for these behaviours for young children in their care. METHODS: This is a qualitative study consisting of six focus groups conducted in Spanish with a sample of 44 state-licensed Latino FCCH providers in the state of Massachusetts. Translated transcripts were analysed using thematic analyses to identify meaningful patterns. RESULTS: Analyses revealed that Latino FCCH providers have positive beliefs and attitudes about the importance of healthy eating and physical activity for children in their care, but personally struggle with these same behaviours and with maintaining a healthy weight status. The ability of Latino FCCH providers to model healthy eating and physical activity may be limited by their low self-efficacy in their ability to be physically active, eat a healthy diet and maintain a healthy weight. CONCLUSIONS: Interventions designed to improve healthy eating and physical activity behaviours of children enrolled in FCCHs should address providers' own health behaviours as well as their modelling of these health behaviours. Future research can build on the findings of this qualitative study by quantifying Latino FCCH providers' eating and physical activity behaviours, and determining how these behaviours influence behaviours and health outcomes of children in their care.

Latinos are the largest minority population group in the United States (U.S.), and low-income Latina women are at elevated risk of depression and obesity. Thus, the prevention of these two problems is a pressing public health concern in this population. Both depressive symptoms and obesity are modifiable factors that can be addressed by culturally relevant interventions. However, the association between depressive symptoms and obesity in Latina immigrant women is not well understood. Therefore, this cross-sectional study examined the association between depressive symptoms and obesity among Latina women of childbearing age (15-44). Participants (n = 147) were low-income, predominantly immigrant Latina mothers enrolled in the Latina Mothers' Child Feeding Practices and Style Study. Women were eligible to participate if they self-identified as Latina; were enrolled in or eligible for the Special Supplemental Nutrition Program for Women, Infants and Children program; had a child between ages two and five years; and were living in the U.S. for at least one year, and residing in Rhode Island. Enrolled participants completed a survey in their language of preference (English or Spanish) administered by bilingual interviewers. About one-third (34%) of participants were classified as having obesity (BMI ≥ 30 kg/m²), 28.3% had elevated depressive symptoms (CES-D ≥ 16), and 70.1% were immigrants. Women with elevated depressive symptoms had increased odds of having obesity (odds ratio (OR) = 2.80, 95% confidence interval (CI): 1.24-6.33). Additionally, among immigrants, length of U.S. residency was associated with increased odds of obesity (OR = 1.05, 95% CI: 1.02-1.09). Findings underscore the need for screening and culturally relevant interventions designed to address both depressive symptoms and obesity among low-income Latina women of childbearing age. Furthermore, findings highlight the importance of taking into account the length of residency in the U.S. when designing interventions targeting Latina immigrants.

BACKGROUND: Childhood obesity is a significant global public health problem due to increasing rates worldwide. Growing evidence suggests that nonresponsive parental feeding styles and practices are important influences on children's eating behaviors and weight status, especially during early childhood. Therefore, understanding parental factors that may influence nonresponsive parental feeding styles and practices is significant for the development of interventions to prevent childhood obesity. OBJECTIVE: The objectives of this systematic review were to (1) identify and review existing research examining the associations between maternal depressive symptoms and use of nonresponsive feeding styles and practices among mothers of young children (2-8 years of age), (2) highlight the limitations of reviewed studies, and (3) generate suggestions for future research. METHODS: Using the PRISMA (Preferred Reporting Items for Systematic review and Meta-Analysis Protocols) guidelines, six electronic academic databases were searched for peer-reviewed, full-text papers published in English between January 2000 and June 2016. Only studies with mothers 18+ years old of normally developing children between 2 and 8 years of age were included. Of the 297 citations identified, 35 full-text papers were retrieved and 8 were reviewed. RESULTS: The reviewed studies provided mixed evidence for associations between maternal depressive symptoms and nonresponsive feeding styles and practices. Two out of three studies reported positive associations with nonresponsive feeding styles, in that mothers with elevated depressive symptoms were more likely than mothers without those symptoms to exhibit uninvolved and permissive or indulgent feeding styles. Furthermore, results of reviewed studies provide good evidence for association between maternal depressive symptoms and instrumental feeding (3 of 3 reviewed studies) and nonresponsive family mealtime practices (3/3), but mixed evidence for pressuring children to eat (3/6) and emotional feeding (1/3). In addition, evidence for the association between maternal depressive symptoms and restricting child food intake was mixed: one study (1/6) found a positive association; two studies (2/6) found a negative association; whereas one study (1/6) found no association. CONCLUSIONS: This review indicates that the results of studies examining the associations between maternal depressive symptoms and parental feeding styles and practices are mixed. Limitations of studies included in this review should be noted: (1) the use of a diverse set of self-report questionnaires to assess parental feeding practices is problematic due to potential misclassification and makes it difficult to compare these outcomes across studies, thus caution must be taken in drawing conclusions; and (2) the majority of included studies (6/8) were cross-sectional. There is a need for additional longitudinal studies to disentangle the influence of depression on parental feeding styles and practices. Nevertheless, given that depressive symptoms and feeding styles and practices are potentially modifiable, it is important to understand their relationship to inform obesity prevention interventions and programs.
RESUMO
PURPOSE: The purpose of this study was to examine the associations between different physical activity (PA) domains, PA recommendations, and leukocyte telomere length (LTL) using data from a nationally representative sample of U.S. adults in the National Health and Nutrition Examination Survey, 1999-2002. METHODS: A total of 6933 U.S. adults (3402 men, 3531 women; age range: 20-84 yr) who completed demographic, general health and PA questionnaires and provided a blood sample were included in the analyses. Multivariable-adjusted linear regression models were used to determine associations between PA (domain-specific PA [household/yard work PA, transportation PA, moderate leisure time PA (LTPA), and vigorous LTPA], total moderate PA and PA recommendation groups), and log-transformed LTL adjusting for age, gender, education, cigarette smoking, alcohol consumption, and body mass index. RESULTS: On average, an increase of 1 h·wk of vigorous LTPA was associated with a 0.31% (P < 0.001) longer LTL, and an increase of 1 h·wk of household/yard work PA was associated with a 0.21% (P = 0.03) shorter LTL while adjusted for sociodemographic and health behavior covariates. Neither transportation PA nor moderate LTPA was significantly associated with LTL. In addition, compared with not meeting the PA recommendation (<150 min·wk), exceeding the recommended PA levels (≥300 min·wk) was positively associated with longer LTL (P = 0.04), whereas there was no difference in telomere length between those not meeting versus those meeting the PA recommendation (150-299 min·wk). CONCLUSION: Greater engagement in vigorous LTPA and exceeding the PA recommendation may have a protective effect against telomere shortening. Future studies should examine the association between PA and LTL by exploring potential mediators such as sedentary behavior, genetics, nutrition, and chronic diseases.

Automated dialogue systems delivered over the telephone offer a promising approach to delivering health-related interventions to populations of individuals at low-cost. Over the past two decades, an automated telephone system called Telephone-Linked Care or TLC has been successfully designed and evaluated by the authors and their colleagues. This work has resulted in over twenty systems for various health-related conditions and lifestyle behaviors. This paper describes our approach to developing and writing dialogue for these automated telephone systems, including determining the program objectives, defining the target population, and selecting a theory of behavior change to guide the intervention. Both macro and micro issues are considered in constructing dialogue systems that are engaging for the target population, easy to use, and effective at promoting positive health behaviors and outcomes.

OBJECTIVE: To assess the validity of 5 parental stage-of-change (SOC) measures: (1) providing 5 servings/d of fruits and vegetables (FV), (2) limiting television (TV) to 2 h/d, (3) helping children achieve 1 h/d physical activity (PA), (4) limiting sugary drinks (SD) to 1 serving/wk, and (5) limiting fruit juice (FJ) to 4-6 oz/d. DESIGN: Cross-sectional instrument development study. Construct validity was evaluated by examining whether parental self-efficacy, parental readiness ladder (ladder), and child's behavioral levels (eg, FV consumption) exhibited a theoretically consistent pattern across the SOC. SETTING/PARTICIPANTS: Convenience sample (n = 283) of parents of children aged 4-10 years. MEASURES: Survey assessed SOC, ladder, and child's behavioral level score for each topic (FV, TV, PA, SD, and FJ), and parental self-efficacy for measure except TV. ANALYSIS: Analysis of variance with Tukey-Kramer post hoc tests examined whether variables differed by SOC. RESULTS: Percentages of parents in the pre-action SOC were 34% (PA), 39% (FV), 42% (SD), 45% (TV), and 63% (FJ). Parental self-efficacy, ladder, and child's behavioral level differed significantly by SOC for each topic area (P < .001). Maintenance SOC was significantly higher than pre-action SOC. CONCLUSIONS AND IMPLICATIONS: Measured variables exhibited a theoretically consistent pattern across SOC, suggesting construct validity and potential usefulness for obesity prevention efforts.
