From coitus to concurrency: sexual partnership characteristics and risk behaviors of 15-19 year old men recruited from urban venues in Tanzania.

Understanding the uptake and patterns of sexual partnerships of adolescent males reveals their risky behaviors that could persist into adulthood. Using venue-based sampling, we surveyed 671 male youth ages 15-19 from an urban Tanzanian neighborhood about their sexual partnerships during the past 6 months. The proportion of males who had ever had sex increased with age (21 % at age 15; 70 % at age 17; 94 % at age 19), as did the proportion who engaged in concurrency (5 % at age 15; 28 % at age 17; 44 % at age 19). Attendance at ≥2 social venues per day and meeting a sexual partner at a venue was associated with concurrency. Concurrency was associated with alcohol consumption before sex among 18-19 year olds and with not being in school among 15-17 year olds. We find that concurrency becomes normative over male adolescence. Venue-based sampling may reach youth vulnerable to developing risky sexual partnership patterns.

Falls Risks and Prevention Behaviors Among Community-Dwelling Homebound and Non-Homebound Older Adults.

The objectives were to examine falls risk factors to determine how the magnitude of risk may differ between homebound and non-homebound older adults, and to describe falls prevention behaviors and participation in falls prevention education. A cross-sectional survey was conducted with convenience samples of community-dwelling older adults recruited through Meals on Wheels programs (homebound, n = 80) and senior centers (non-homebound, n = 84) in North Carolina. Data were collected during home visits and included an interview and medication inventory. Multivariate negative binomial regression with robust variance estimation modeled risk factors for falls. Risk factors for falls observed in both the homebound and non-homebound populations are consistent with what is known in the literature. However, the magnitude of the risk was higher in the homebound than in the non-homebound population with respect to vision impairments, number of high-risk and over-the-counter medications, and use of walking aids .Few participants reported participating in a falls prevention program.

Relationship Between Perceived Risk of Falling and Adoption of Precautions to Reduce Fall Risk.

OBJECTIVES: To better understand the relationship between perceived risk of falling and awareness and adoption of four specific precautions that older adults have taken to reduce this risk. DESIGN: Cross-sectional. SETTING: Data were collected in in-person interviews conducted in the homes of study participants. Interviews conducted between March 2011 and September 2013 and lasted an average of 60-90 minutes. PARTICIPANTS: A stratified sampling strategy designed to enroll an equal number of homebound and nonhomebound participants was used. All participants (N = 164) were recruited from central North Carolina. MEASUREMENTS: Participants were asked about 1-year fall history, perceived risk of falling, restriction of activities because of fear of falling, awareness of four recommended fall prevention behaviors (exercise, annual medication review, bathroom grab bars, safe footwear), and current practice of these behaviors. RESULTS: In bivariate analyses, individuals who were aware of two behaviors recommended to reduce the risk of falling (exercise, use of safe footwear) and had adopted these behaviors perceived their risk of falling as lower than individuals who were aware of the recommended behaviors but had not adopted them. Moreover, in multivariate analyses, individuals who did not know that exercise is recommended to reduce the risk of falling perceived their risk of falling as lower than those who were aware of this recommendation and had adopted it. Individuals were least likely to be aware that medication reviews and exercise are recommended to reduce fall risk. CONCLUSION: Awareness of behaviors recommended to reduce fall risk appears necessary for adoption of these behaviors to reduce perceived risk. Fall-prevention campaigns should emphasize behaviors where awareness is low.

Strength and Comprehensiveness of School Wellness Policies in Southeastern US School Districts.

BACKGROUND: In 2004, Congress passed legislation mandating that all public school districts participating in federal school meal programs develop a school wellness policy (SWP) to direct efforts related to nutrition and physical activity. We examined the extent to which SWPs varied in comprehensiveness and strength in a representative sample of school districts in the southeastern United States, the area of the country with the highest rates of childhood obesity. METHODS: Policies were assessed using an established 96-item coding tool by 2 raters to ascertain the comprehensiveness and strength of the policies as a whole, and across distinct subsections specified by federal legislation. In addition, variability in SWP comprehensiveness and strength was assessed based on district sociodemographic characteristics. RESULTS: Overall, SWPs in the southeastern states are weakly written, fragmented, and lack requirements necessary for healthy school environments. District size, which was the only sociodemographic factor related to policy characteristics, yielded an inverse association. CONCLUSIONS: To encourage continued promotion of healthy school environments, school districts will require technical support to improve the quality of their school wellness policies.

Increasing provision of adolescent vaccines in primary care: a randomized controlled trial.

OBJECTIVES: To assess the effectiveness of in-person and webinar-delivered AFIX (Assessment, Feedback, Incentives, and eXchange) consultations for increasing adolescent vaccine coverage. METHODS: We randomly assigned 91 primary care clinics in North Carolina, serving 107 443 adolescents, to receive no consultation or an in-person or webinar AFIX consultation. We delivered in-person consultations in April through May 2011 and webinar consultations in May through August 2011. The state's immunization registry provided vaccine coverage data for younger patients (ages 11-12 years) and older patients (ages 13-18 years) for 3 adolescent vaccines: tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap); meningococcal; and human papillomavirus (HPV) vaccines (≥1 dose, females only). RESULTS: At the 5-month follow-up, AFIX consultations increased vaccine coverage among younger adolescents. Patients in the in-person arm experienced coverage changes that exceeded those in the control arm for Tdap (3.4% [95% confidence interval (CI): 2.2 to 4.6]), meningococcal (4.7% [95% CI: 2.3 to 7.2], and HPV (1.5% [95% CI: 0.3 to 2.7]) vaccines. Patients in the webinar versus control arm also experienced larger changes for these vaccines. AFIX did little to improve coverage among older adolescents. At 1 year, the 3 arms showed similar coverage changes. The effectiveness of in-person and webinar consultations was not statistically different at either time point (all, P >.05). CONCLUSIONS: Webinar AFIX consultations were as effective as in-person consultations in achieving short-term increases in vaccine coverage for younger adolescents. AFIX consultations for adolescents need improvement to have a stronger and more durable impact, especially for HPV vaccine.
