Frequency of soil contamination by Toxocara canis eggs in the south region of Sao Paulo municipality (SP, Brazil) in a 18 month period. (25/142)

Soil contamination by embryonic eggs of Toxocara canis is the main source of human infection by this ascarid larvae resulting, sometimes, in the occurrence of visceral larva migrans syndrome. The objective of the present research is to determine the frequency of T. canis eggs in soil samples monthly collected in nine public places, located at the South Region of Sao Paulo municipality in a 18-month period, from February 2004 to July 2005. The soil samples collected were treated with a 30% antiformine solution and with a sodium dichromate solution (d = 1.40) and microscopic slides were prepared and examined under light microscopy for searching T. canis eggs. Two peaks of higher frequency had been found, one in February-May 2004 and the other in April-July 2005.  (+info)

"There is such a thing as asking for trouble": taking rapid HIV testing to gay venues is fraught with challenges. (26/142)

OBJECTIVES: To explore the feasibility and acceptability of offering rapid HIV testing to men who have sex with men in gay social venues. METHODS: Qualitative study with in-depth interviews and focus group discussions. Interview transcripts were analysed for recurrent themes. 24 respondents participated in the study. Six gay venue owners, four gay service users and one service provider took part in in-depth interviews. Focus groups were conducted with eight members of a rapid HIV testing clinic staff and five positive gay men. RESULTS: Respondents had strong concerns about confidentiality and privacy, and many felt that HIV testing was "too serious" an event to be undertaken in social venues. Many also voiced concerns about issues relating to post-test support and behaviour, and clinical standards. Venue owners also discussed the potential negative impact of HIV testing on social venues. CONCLUSION: There are currently substantial barriers to offering rapid HIV tests to men who have sex with men in social venues. Further work to enhance acceptability must consider ways of increasing the confidentiality and professionalism of testing services, designing appropriate pre-discussion and post-discussion protocols, evaluating different models of service delivery, and considering their cost-effectiveness in relation to existing services.  (+info)

Availability of recreational resources and physical activity in adults. (27/142)

OBJECTIVES: Using data from a large cohort of adults aged 45 to 84 years-old, we investigated whether availability of recreational resources is related to physical activity levels. METHODS: Data from a multiethnic sample of 2723 adult residents of New York City, NY; Baltimore, Md; and Forsyth County, NC, were linked to data on locations of recreational resources. We measured the availability (density) of resources within 0.5 (0.8 km), 1, 2, and 5 miles of each participant's residence and used binomial regression to investigate associations of density with physical activity. RESULTS: After adjustment for potential confounders, individuals in the tertile of participants residing in areas with the highest density of resources were more likely to report physical activity during a typical week than were individuals in the lowest tertile. Associations between availability of recreational resources and physical activity levels were not present for the smallest area assessed (0.5 miles) but were present for areas ranging from 1 to 5 miles. These associations were slightly stronger among minority and low-income residents. CONCLUSIONS: Availability of resources may be 1 of several environmental factors that influence individuals' physical activity behaviors.  (+info)

Homelessness, health status, and health care use. (28/142)

OBJECTIVES: Little is known about the health status of those who are newly homeless. We sought to describe the health status and health care use of new clients of homeless shelters and observe changes in these health indicators over the study period. METHODS: We conducted a longitudinal study of 445 individuals from their entry into the homeless shelter system through the subsequent 18 months. RESULTS: Disease was prevalent in the newly homeless. This population accessed health care services at high rates in the year before becoming homeless. Significant improvements in health status were seen over the study period as well as a significant increase in the number who were insured. CONCLUSION: Newly homeless persons struggle under the combined burdens of residential instability and significant levels of physical disease and mental illness, but many experience some improvements in their health status and access to care during their time in the homeless shelter system.  (+info)

Contribution of public parks to physical activity. (29/142)

OBJECTIVES: Parks provide places for people to experience nature, engage in physical activity, and relax. We studied how residents in low-income, minority communities use public, urban neighborhood parks and how parks contribute to physical activity. METHODS: In 8 public parks, we used direct observation to document the number, gender, race/ethnicity, age group, and activity level of park users 4 times per day, 7 days per week. We also interviewed 713 park users and 605 area residents living within 2 miles of each park. RESULTS: On average, over 2000 individuals were counted in each park, and about two thirds were sedentary when observed. More males than females used the parks, and males were twice as likely to be vigorously active. Interviewees identified the park as the most common place they exercised. Both park use and exercise levels of individuals were predicted by proximity of their residence to the park. CONCLUSIONS: Public parks are critical resources for physical activity in minority communities. Because residential proximity is strongly associated with physical activity and park use, the number and location of parks are currently insufficient to serve local populations well.  (+info)

Asthma among homeless children in New York City: an update. (30/142)

Homeless children in New York City had an extremely high asthma prevalence-40%-in a cross-sectional study at 3 shelters (n=740) during 1998 to 1999. We used the same protocol to summarize subsequent data through December 2002. Asthma prevalence was 33% (n=1636); only 15% of the children previously diagnosed were taking an asthma controller medication. Emergency department use was 59%. These data were used to support a class action lawsuit that was resolved in favor of homeless children with asthma in New York City.  (+info)

Economic effect of a smoke-free law in a tobacco-growing community. (31/142)

OBJECTIVE: To determine whether Lexington, Kentucky's smoke-free law affected employment and business closures in restaurants and bars. On 27 April 2004, Lexington-Fayette County implemented a comprehensive ordinance prohibiting smoking in all public buildings, including bars and restaurants. Lexington is located in a major tobacco-growing state that has the highest smoking rate in the US and was the first Kentucky community to become smoke-free. DESIGN: A fixed-effects time series design to estimate the effect of the smoke-free law on employment and ordinary least squares to estimate the effect on business openings and closings. SUBJECTS AND SETTINGS: All restaurants and bars in Lexington-Fayette County, Kentucky and the six contiguous counties. MAIN OUTCOME MEASURES: ES-202 employment data from the Kentucky Workforce Cabinet; Business opening/closings data from the Lexington-Fayette County Health Department, Environmental Division. RESULTS: A positive and significant relationship was observed between the smoke-free legislation and restaurant employment, but no significant relationship was observed with bar employment. No relationship was observed between the law's implementation and employment in contiguous counties nor between the smoke-free law and business openings or closures in alcohol-serving and or non-alcohol-serving businesses. CONCLUSIONS: No important economic harm stemmed from the smoke-free legislation over the period studied, despite the fact that Lexington is located in a tobacco-producing state with higher-than-average smoking rates.  (+info)

Comparing perceived and objectively measured access to recreational facilities as predictors of physical activity in adolescent girls. (32/142)

A number of studies in recent years have identified both self-report and objectively measured accessibility of recreational facilities as important predictors of physical activity in youth. Yet, few studies have: (1) examined the relationship between the number and proximity of objectively measured neighborhood physical activity facilities and respondents' perceptions and (2) compared objective and self-report measures as predictors of physical activity. This study uses data on 1,367 6th-grade girls who participated in the Trial of Activity for Adolescent Girls (TAAG) to explore these issues. Girls reported whether nine different types of recreational facilities were easily accessible. These facilities included basketball courts, golf courses, martial arts studios, playing fields, tracks, skating rinks, swimming pools, tennis courts, and dance/gymnastic clubs. Next, geographic information systems (GIS) were used to identify all the parks, schools, and commercial sites for physical activity located within a mile of each girl's home. These sites were then visited to inventory the types of facilities available. Girls wore accelerometers to measure their weekly minutes of non-school metabolic equivalent weighted moderate-to-vigorous physical activity (MW-MVPA). The number of facilities within a half-mile of girls' homes strongly predicted the perception of easy access to seven out of nine facility types. Both individual facility perceptions and the total number of facilities perceived were associated with increased physical activity. For each additional facility perceived, girls clocked 3% more metabolic equivalent weighted moderate-to-vigorous physical activity (p < 0.001). Although girls tended to record 3% more of this kind of physical activity (p < 0.05) per basketball court within a mile of their homes, objective facility measures were otherwise unrelated to physical activity. The results from this study suggest that raising the profile of existing facilities may help increase physical activity among adolescent girls.  (+info)
