Associations Between Neighborhood Characteristics and Physical Activity Among Youth Within Rural–Urban Commuting Areas in the US

The association among rural–urban communities, neighborhood characteristics, and youth physical activity is inconsistent in the literature. We used data from the 2007 National Survey of Children’s Health, for youth aged 10–17 years (n = 45,392), to examine the association between physical activity and neighborhood characteristics, after adjusting for known confounders. We also examined the association between physical activity and neighborhood characteristics within seven levels of Rural–Urban Commuting Areas (RUCAs) that depict a continuum from isolated rural to dense urban communities. Attainment of a minimum physical activity level differed by RUCA (P = 0.0004). In adjusted, RUCA-specific models, the presence of parks was associated with attaining a minimum physical activity level in only one of the seven RUCAs (adjusted odds ratio: 3.49; 95 % confidence interval: 1.55, 7.84). This analysis identified no association between youths’ minimum physical activity attainment and neighborhood characteristics in unstratified models; and, RUCA-specific models showed little heterogeneity by rural–urban community type. Although this analysis found little association between youth physical activity and neighborhood characteristics, the findings could reflect the crude categorization of the neighborhood amenities (sidewalks, parks, recreation centers) and detracting elements (litter, dilapidated housing, vandalism) and suggests that simple measurement of the presence of an amenity or detracting element is insufficient for determining potential associations with reaching minimum levels of physical activity. By exploring neighborhood characteristics and features of neighborhood amenities within the context of well-defined community types, like RUCAs, we can better understand how and why these factors contribute to different levels of youth physical activity.     

The Effect of a 2-Year Intervention Consisting of Diet,Physical Exercise,Cognitive Training,and Monitoring of Vascular Risk on Chronic Morbidity—the FINGER Randomized Controlled Trial

Objective

To verify whether a multidomain intervention lowers the risk of developing new chronic diseases in older adults.

Positive Effects of “Textured Lunches” Gatherings and Oral Exercises Combined with Physical Exercises on Oral and Physical Function in Older Individuals: A Cluster Randomized Controlled Trial

Objectives

Proper nutrition and physical exercises are essential to prevent frailty in older adults. Proper masticatory performance and oral function may influence on physical activities as well since the mouth is the entrance of nutrition and digestion. Thus, the present study aimed to test the combined program of specially devised lunch gatherings containing textured foods with oral and physical exercises on the improvement of oral and physical function in community-dwelling older adults.

Design

A Cluster randomized controlled trial

Setting and Participants

Eighty-six community-dwelling older adults in Daito city, Japan, were randomly assigned into control (n = 43) or intervention (n = 43) groups.

Intervention

The control group performed the physical exercise regimen only. The intervention group participated in a 12-week physical and oral exercise program and ate a so-called “munchy lunch” that introduced textured foods with proper nutrients together after performing the physical exercise twice a week following brief dietary instruction at the intervention onset. Physical training and lunch gatherings were held at local public centers.

Measurements

The differences in measured variables for physical and oral function between baseline and 12 weeks of intervention were statistically tested. Results: Oral function as measured by tongue pressure increased significantly in the intervention group (p=0.031), but not in the control group. Physical properties and activities, including body fat percentage and results of the timed up and go test, decreased more significantly in the intervention group than in controls (p<0.05).

Conclusions

Our findings suggest that a combined program of textured lunch gatherings with oral and physical exercises may improve physical and oral function as a preventative approach for frailty in community-dwelling older adults.

     

“When Diet and Exercise Are Not Enough”: An Examination of Lifestyle Change Inefficacy Claims in Direct-to-Consumer Advertising

Previous research suggests that direct-to-consumer (DTC) advertisements for pharmaceutical drugs have the potential to influence consumers’ perceptions of whether symptoms should be treated medically and/or through behavior change. However, the relative frequency of messages emphasizing these approaches in pharmaceutical advertising remains largely unknown. A content analysis of print and television advertisements for cholesterol management medication between 1994 and 2005 (for print) and between 1999 and 2007 (for television) was conducted. First, the extent to which established theoretical constructs drawn from health communication scholarship are depicted in the content of DTC cholesterol advertisements is quantified. Second, specific claims about behavior change inefficacy when a pharmaceutical alternative is available are identified. Findings indicate that DTC ads offer many mixed messages about the efficacy of diet and exercise in reducing cholesterol and risk of heart disease. Theoretical and practical implications of this work are discussed.     

HIV Care Cascade Among Adolescents in a “Test and Treat” Community-Based Intervention: HPTN 071 (PopART) for Youth Study

PurposeThe PopART for Youth (P-ART-Y) study was nested within the HPTN 071 (PopART) trial, a three-arm community randomized trial in 21 communities in Zambia and South Africa. The P-ART-Y study evaluated the acceptability and uptake of a combination HIV prevention package among young people. We report on the HIV care cascade for adolescents aged 10–19 years from 14 communities receiving the full HIV prevention package in Zambia and South Africa.MethodsAdolescents were offered participation in the PopART intervention, which included universal home-based HIV testing, linkage to care, antiretroviral therapy (ART) adherence, and other services. Data were collected from September 2016 to December 2017, covering the third round (R3) of the intervention.ResultsWe enumerated (listed) 128,241 adolescents (Zambia: 95,295 and South Africa: 32,946). Of the adolescents offered HIV testing, 81.9% accepted in Zambia and 70.3% in South Africa. Knowledge of HIV status was higher among older adolescents and increased from 31.4% before R3 to 88.3% at the end of R3 in Zambia and from 28.3% to 79.5% in South Africa. Overall, there were 1,710 (1.9%) adolescents identified as living with HIV by the end of R3 (515 new diagnoses and 1,195 self-reported). Of the new diagnoses, 335 (65.0%) were girls aged 15–19 years. The median time to initiate ART was 5 months. ART coverage before and after R3 increased from 61.3% to 78.7% in Zambia and from 65.6% to 87.8% in South Africa, with boys having higher uptake than girls in both countries.ConclusionsThe PopART intervention substantially increased coverage toward the first and second UNAIDS 90-90-90 targets in adolescents.     

Evolution of Serum 25OHD in Response to Vitamin D3–Fortified Yogurts Consumed by Healthy Menopausal Women: A 6-Month Randomized Controlled Trial Assessing the Interactions between Doses,Baseline Vitamin D Status,and Seasonality

Background: Adequate vitamin D status contributes to bone fragility risk reduction and possibly other pathological conditions that occur with aging. In response to pharmaceutical vitamin D₃ supplements, several studies have documented the influence of doses, baseline status, and seasonality on serum 25-hydroyvitamin D (s25OHD).

Objective: Using fortified yogurt, we investigated in one randomized controlled trial how both baseline status, as assessed by measuring s25OHD prior the onset of the trial, and the season of enrollment quantitatively influenced the response to the supplemented (Suppl.) of vitamin D₃ (VitD₃) in healthy community-dwelling women.

Methods: A 24-week controlled trial was conducted in menopausal women (mean age: 61.5). Participants were randomized into 3 groups (Gr): Gr.Suppl.0, time controls maintaining dietary habits; Gr.Suppl.5 and Gr.Suppl.10 consuming one and two 125-g servings of VitD₃-fortified yogurts with 5- and 10-µg daily doses, respectively. The 16 intervention weeks lasted from early January to mid-August, the 8 follow-up weeks, without product, from late August to mid-October. Before enrollment, subjects were randomized into 2 s25OHD strata: low stratum (LoStr): 25–50 nmol/L; high stratum (HiStr): >50–75 nmol/L.

Results: All enrolled participants adhered to the protocol throughout the 24-week study: Gr.Suppl.0 (n = 45), Gr.Suppl.5 (n = 44), and Gr.Suppl.10 (n = 44). Over the 16 intervention and 8 follow-up weeks, s25OHD increased in both supplemented groups, more in Gr.Suppl.10 than in Gr.Suppl.5. At the end of the intervention, the subject proportion with s25OHD ≥ 50 nmol/L was 37.8, 54.5, and 63.6% in Gr.Suppl.0, Gr.Suppl.5, and Gr.Suppl.10, respectively. The constant rate of s25OHD per supplemental VitD₃ microgram was greater in LoStr than HiStr. The s25OHD increase was greater with late (mid-March) than early (mid-January) inclusion.

Conclusion: This randomized trial demonstrates (1) a dose-dependent s25OHD improvement related to fortified yogurt consumption; (2) an inversely baseline-dependent increase in s25OHD; and (3) a seasonal effect that highlights the importance of VitD₃-fortified foods during winter, even at 5 µg/d, in healthy menopausal women.     

Understanding Process in Group-Based Intervention Delivery: Social Network Analysis and Intra-entity Variability Methods as Windows into the “Black Box”

Although the majority of evidence-based programs are designed for group delivery, group process and its role in participant outcomes have received little empirical attention. Data were collected from 20 groups of participants (94 early adolescents, 120 parents) enrolled in an efficacy trial of a mindfulness-based adaptation of the Strengthening Families Program (MSFP). Following each weekly session, participants reported on their relations to group members. Social network analysis and methods sensitive to intraindividual variability were integrated to examine weekly covariation between group process and participant progress, and to predict post-intervention outcomes from levels and changes in group process. Results demonstrate hypothesized links between network indices of group process and intervention outcomes and highlight the value of this unique analytic approach to studying intervention group process.     

Alcohol Expectancies and Risky Drinking Behaviors Among High School Athletes: “I’d Rather Keep My Head in the Game”

Research suggests that high school students who participate in sports may be at elevated risk for alcohol use compared to their non-athlete peers; however, reasons for this association are unclear. Alcohol expectancy theory posits that individuals who expect favorable outcomes to occur because of alcohol use are more likely to drink than those who do not endorse such beliefs. As such, the present study was designed to examine the associations of alcohol expectancy outcomes and valuations (i.e., beliefs about whether an outcome is good or bad), as well as alcohol expectancies related to sports functioning (e.g., alcohol’s effects on one’s ability to learn new plays and recover physically from sporting activities), with risky drinking among high school athletes. Participants were 219 in-season high school athletes (mean age = 15.6, range = 13–18) who completed anonymous self-report surveys. A structural equation model indicated that endorsement of positive alcohol expectancy outcomes and favorable evaluations of negative expectancy outcomes were associated with higher levels of risky drinking. Conversely, greater endorsement of negative athletic-functioning drinking expectancies was associated with lower levels of risky drinking. Future research considerations and implications for intervention efforts targeting high school athletes are discussed.     

“Food Doesn’t Have Power Over Me Anymore!” Self-Efficacy as a Driver for Dietary Adherence Among African American Adults Participating in Plant-Based and Meat-Reduced Dietary Interventions: A Qualitative Study

BackgroundAfrican American (AA) adults are disproportionately affected by cardiovascular disease risk factors. Many nutrition interventions aim to promote healthier eating to reduce cardiovascular disease incidences among participants. However, little is known about what influences individuals’ nutrition self-efficacy while participating in these interventions.ObjectiveThe objective of this study is to explore the drivers and barriers of nutrition self-efficacy among Nutritious Eating With Soul (NEW Soul) participants. The NEW Soul study was funded from the National Heart, Lung, and Blood Institute.DesignA purposive-current study sampling was used to conduct 4 audio-recorded focus groups for this qualitative study. Bandura’s self-efficacy theory of behavior change guided the framework. This theory asserts that individual self-efficacy is influenced by 4 factors: (1) mastery experiences, (2) vicarious experiences, (3) social persuasion, and (4) somatic and emotional states.Participants/settingInclusion criteria for the NEW Soul program included being an AA, being between 18 and 65 years old, and having a body mass index between 25 and 49.9. Participants in cohort 2 (n = 84) of the NEW Soul program were asked to participate in focus groups. In total, 28 individuals (16 vegan, 12 omnivorous participants) took part in 4 in-person focus groups, which contained 3 to 13 participants. Focus groups took place in the southeastern United States.Main outcome measurePerception of drivers and barriers of following the diet.Statistical analysisResponses were analyzed qualitatively using principles of content analysis.ResultsNine themes influenced participants’ confidence in their ability to follow their diet: food preference, planning and preparation, identity and tradition, mindfulness, representation, social support, social influence, accountability, and state of mind.ConclusionIn this study, self-efficacy played a prominent role in participants’ motivations toward following the diet. Mastery experiences, vicarious experiences, social persuasion, and positive psychological arousal were all common themes in participant-reported sources of motivation. Nutrition interventions are likely to elicit positive behavioral outcomes if these 4 factors that enhance self-efficacy are incorporated into program development.     

Family Predictors of Psychosocial Outcomes Among Hong Kong Chinese Cancer Patients in Palliative Care: Living and Dying with the “Support Paradox”

A good death is universally desired. For Chinese patients, the family is believed to play a key role in making this possible. This study aims at exploring the relationship of family-related factors and psychosocial outcomes among Hong Kong Chinese cancer patients in palliative care. Clinical data mining was adopted as the research method. Nurses collected data from clinical interviews with incoming palliative care patients. A total of 935 patients from three years of deceased patient records was included. Stepwise regression analysis demonstrated that “caregivers' support and acceptance” predicted fewer psychosocial symptoms of patients, whereas “depressed family response to patient's illness” and “family anxiety” predicted a greater number of psychosocial symptoms of patients upon their admission to palliative care. The findings suggested two possible pathways toward enhancing the psychosocial experience of dying patients, that is, the “family support pathway” and the “familial-altruistic pathway.” Further reflections on the findings may suggest that these patients may be situated in a “support paradox,” in which they desire family support but also worry about the burden that support places on family members. Implications for practice were discussed in the cultural context.     

Examining the Relationship between Message Variables,Affective Reactions,and Parents’ Instrumental Attitudes toward Their Child’s Physical Activity: The “Mr. Lonely” Public Service Announcement

This study examined the relationship between message variables and affective reactions with parents’ attitudes after seeing a physical activity mass media public service announcement (PSA). It was hypothesized that there would be a positive relationship between message variables (i.e., personal relevance, novelty of information, and feelings toward sponsoring organization) and parents’ attitudes toward their child/children’s physical activity after viewing the PSA. Furthermore, we explored whether discrete affective reactions were related to attitudes, beyond the effect of message variables. A secondary data analysis was conducted with parental responses to an online campaign evaluation survey (n = 267). Hierarchical regression analyses showed an overall positive relationship between all three message variables and attitudes. Furthermore, two discrete affective reactions were positively related to attitudes. Parents who endorsed feeling motivated or guilty after viewing the advertisement had more positive attitudes toward their children’s physical activity levels. This study represents an ecologically valid assessment of how message variables and affective reactions are related to attitudes within the context of a physical activity mass media campaign. The results provide guidance for the effective design of mass media physical activity campaigns.
