Low response rate schools in surveys of adolescent risk taking behaviours: possible biases, possible solutions.

STUDY OBJECTIVE: To examine the potential biases introduced when students in low response rate schools are dropped from classroom based surveys of adolescent risk taking behaviour. DESIGN: Self administered confidential surveys were conducted in classrooms, with follow up visits to each school to survey students absent during the initial survey administration. Data on students in schools that achieved a 70% response rate are compared with data on students in schools that did not achieve this level of response. SETTING: New York City, United States. PARTICIPANTS: 1854 10th graders in 13 public (state supported) high schools. MAIN RESULTS: Students in schools with low response rates resulting from high rates of absenteeism have different demographic characteristics and engage in more risk behaviours than students in schools with low absenteeism and high response rates. Excluding schools with low rates of response can have an effect on estimates of risk behaviour, even after data are weighted for individual absences. The potential for bias is greatest when, in sampling schools, the proportion of schools with low response rates is large, and when such schools represent a large share of the students in the area under study. CONCLUSIONS: Excluding schools with poor response rates from survey samples using a classroom based approach does not improve, and may, under some circumstances, underestimate risky behaviour among adolescent populations.

Strategies for partner notification for sexually transmitted diseases.

BACKGROUND: Partner notification has been practiced for decades, with substantial resources directed towards it, and with little evidence on whether it has made a public health impact on disease transmission. Most of the evaluations were not randomized controlled trials, and were conducted in the United States, prior to the HIV/AIDS epidemic. There are reasons to question whether partner notification for gonorrhoea and chlamydia is applicable to HIV. It is also questionable whether interventions for the developed world are applicable to the developing world. OBJECTIVES: This review aims to compare the effects of various sexually transmitted disease (STD) partner notification strategies, including to compare provider referral with contract and patient referral, and to compare different patient referral strategies to each other. In addition to updating previous reviews, it addresses partner notification in developing countries as well as in developed countries, with particular consideration for HIV/AIDS. It attempts to address some of the methodological limitations of earlier reviews. SEARCH STRATEGY: The search strategy included MEDLINE, EMBASE, Psychological Abstracts, Sociological Abstracts, the Cochrane Controlled Trials register, the proceedings of the International AIDS Conferences and the International Society for STD Research meetings. SELECTION CRITERIA: The review includes published or unpublished randomised controlled trials (RCTs) comparing two or more partner notification strategies for people diagnosed with STDs. DATA COLLECTION AND ANALYSIS: For each comparison within each study, the difference in the rate of partners elicited, notified, medically evaluated, harmed, etc, the 95% confidence interval, and if significant, the numbers needed to treat (NNT) were calculated. MAIN RESULTS: We found 11 RCTs, including 8014 participants. Only two trials were conducted in developing countries, and only two trials were conducted among HIV positive patients. There was some risk of bias in all the included trials. The review found moderately strong evidence that: 1. provider referral alone, or the choice between patient and provider referral, when compared with patient referral among patients with HIV or any STD, increases the rate of partners presenting for medical evaluation; 2. contract referral, when compared with patient referral among patients with gonorrhoea, results in more partners presenting for medical evaluation; 3. verbal, nurse-given health education together with patient-centred counselling by lay workers, when compared with standard care among patients with any STD, results in small increases in the rate of partners treated. REVIEWER'S CONCLUSIONS: There is a need for evaluations of interventions combining provider training and patient education, and for evaluations conducted in developing countries. All partner notification evaluations, but especially those among HIV positive patients, need to measure potential harmful effects, such as domestic violence, to ensure that partner notification does more good than harm.

Condom availability in New York City public high schools: relationships to condom use and sexual behavior.

OBJECTIVES: This study examines the impact of the condom availability program in New York City public high schools by comparing rates of sexual activity and condom use for New York students and similar students in Chicago. METHODS: A total of 7119 students from 12 randomly selected New York schools and 5738 students from 10 Chicago schools participated in a cross-sectional survey. RESULTS: New York students, compared with Chicago students, reported equal rates of sexual activity but higher rates of condom use at last intercourse (odds ratio [OR] = 1.36). For higher-risk students (those with three or more sexual partners in the past 6 months), condom use was greater in New York (OR = 1.85) than in Chicago. CONCLUSIONS: Condom availability has a modest but significant effect on condom use and does not increase rates of sexual activity. These findings suggest that school-based condom availability can lower the risk of HIV and other sexually transmitted diseases for urban teenagers in the United States.

Parents' attitudes and beliefs about HIV/AIDS prevention with condom availability in New York City public high schools.

In 1991, the New York City Board of Education expanded HIV/AIDS education to include condom availability in every public high school. The evaluation was designed to examine the impact of the program on students and monitor changes in parent's knowledge, attitudes, and beliefs. Findings are reported from the first wave of data from the parent survey, 716 parents from 12 randomly chosen NYC high schools and 81 parents from 12 focus groups held at six of the schools. Sixty-nine percent of parents believed students should be able to receive condoms at school, although nearly half felt they should have the right to keep their children from doing so. Most believed making condoms available would result in safer sex practices among students who were sexually active. Data suggest parents support the school's role in reducing HIV/AIDS transmission among adolescents and believe making condoms available represents an acceptable component of an HIV/AIDS prevention program.

The evolution of a public health policy: health care providers and the transmission of HIV.

The single known instance of transmission of HIV from a health care provider to a patient raised issues concerning the responsibility of clinicians to their patients, and sparked debate over policies to prevent the spread of HIV in health care facilities. The intensity and politicization of the debate were reflected in revision of the Centers for Disease Control guidelines to control the spread of infection at health care facilities, and in legislation proposed in Congress. The guidelines and proposed legislation provoked responses by public health and medical organizations, several of which considered the measures to be unnecessarily restrictive and too costly in terms of potential benefits. This article describes the events and responses that took place during 1991-1992 after the public was made aware of the case involving transmission from provider to patient. The author examines the situation in the context of public health efforts to control the spread of HIV.

The prevention of health risks in Cuba.

Cuba still has a double burden of health risks. It must contend with some risks to health that persist in underdeveloped rural areas, and it must also deal with the risk factors associated with modern, urban living conditions. The economic and social changes fostered in the postrevolutionary period have reduced the relative importance of the first set of factors, but the changes have also introduced or intensified a myriad of factors derived from their own successes. In this article, the risk factors of greatest concern in contemporary Cuba are described, and the strategies adopted to combat these risk factors, together with the ways in which such strategies are shaped by Cuba's social and economic development are discussed.

Immigrant workers: health, law, and public policy.

Immigrant workers are a large segment of the lower echelon of the U.S. labor force, and as many as 3.6 to 6 million of these workers and their families are living in the U.S. illegally. This paper examines who the recent immigrants are: explains why their current situation in the U.S. is an important public health matter; discusses the ethical and policy issues stemming from their health needs and from illegal status; and concludes with a brief look at some implications of the Simpson-Mazzoli Immigration and Reform Act, currently before Congress. The paper suggests that the illegal status of undocumented workers intensifies their health risks; that the immigrants' responsibility for budget short-falls in public services is not as clearcut as frequently assumed; and that legislation aimed at regulating the status of immigrant workers in the U.S. is unlikely to solve many of the central problems.
