HIV prevalence and risk behaviours among foreign migrant women residing in Cape Town, South Africa.

HIV prevalence and risk behaviour among foreign migrants in South Africa has not been explored. This paper describes the effectiveness of respondent-driven sampling (RDS) to recruit foreign migrant women residing in Cape Town, reports HIV prevalence, and describes key characteristics among them. We conducted a biological and behavioural surveillance survey using RDS. After written informed consent, participants completed an audio computer assisted self-interview and provided a dried blood sample for HIV analysis. HIV prevalence was estimated to be 7 % (CI 4.9-9.5) among 935 women. HIV sero-positivity was associated with older age (p = 0.001), country of origin (p < 0.000), being unmarried (p < 0.000), having lived in South Africa for 3-5 years (p = 0.023), sexual debut at ≥15 years (p = 0.047), and having used a condom at last sex with a main partner (p = 0.007). Few women reported early sexual debut, or multiple sexual partners. RDS was successful in recruiting foreign migrant women.

Utilization patterns and perceptions of playground users in New York City.

Playgrounds are assumed to be an important resource for physical activity. This study investigates seasonal utilization, user preferences, and perceptions of safety and upkeep of public playgrounds in New York City. A cross-sectional survey was conducted from May 2010 to January 2011 across 10 playgrounds in low/middle income neighborhoods in each of the five boroughs in New York City. A total of 1,396 adults accompanying children were surveyed. Outcomes included playground as main place of outdoor play, and perceptions of playground upkeep and safety. Covariates included socio-demographics and other characteristics of playground users. Multivariable logistic regression with playground/season fixed effects were used. Utilization varied substantially across the four seasons. Blacks had higher odds of reporting the playground as the main place of outdoor play (AOR 1.78, 95 % CI 1.13-2.80, p < .05). High income users had lower odds of reporting the playground as the main place of outdoor play ($60-$80,000: AOR 0.47, 95 % CI 0.29-0.76, p < .01, $80,000+: AOR 0.47, 95 % CI 0.28-0.79, p < .01). Racial differences in perceived upkeep and safety were not significant once playground/season fixed effects were included, highlighting the importance of neighborhood conditions. Women were more likely to report feeling unsafe within playgrounds (AOR 1.51, 95 % CI 1.12-2.02, p < .01). While some playground utilization is driven by individual characteristics, perceptions of public resources influences utilization and cannot be separated from neighborhood conditions. Increasing access to opportunities for physical activity for children requires new strategies beyond playground improvements.
