Effectiveness of an educational intervention on vulvo-vaginal discharge for family healthcare workers: A nonrandomized controlled trial

Women's delay in seeking medical advice for abnormal vaginal discharge can cause serious effects such as infertility, ectopic pregnancy, and advanced cervical cancer. Family healthcare workers are in a unique position to help in the promotion of vaginal health. A nonrandomized controlled trial was conducted among a sample of family healthcare workers in the intervention (n = 37) and a control (n = 37) group to assess the effectiveness of an educational intervention, which was a 2-day intensive workshop combining reading materials. Data were analyzed using SPSS software (version 20), and the effectiveness of the intervention was determined using a mixed between-within subjects analysis of variance. The total knowledge and attitude scores were significantly greater for family healthcare workers in the intervention group immediately and at 3 and 6 months after the educational intervention, compared to the control group. A substantial main effect was observed concerning the time, showing an increase in family healthcare workers' knowledge and attitude scores across the four time periods. A statistically significant difference in the median overall health education competency score across the two groups was also observed. The mean score differences in all sub-competencies in health education were significantly higher among the intervention group, compared to the control group between second postintervention and the baseline. The educational intervention had revealed successful and sustainable improvements in family healthcare workers' knowledge, attitude on vaginal discharge, and health education competency. This can be implemented as an in-service program for family healthcare workers to improve health education practices.

Interventions to reduce risk for sexually transmitted infections in adolescents: A meta-analysis of trials, 2008-2016

BACKGROUND

Numerous studies have evaluated the efficacy of interventions to reduce risk for sexually transmitted infections in adolescents in recent years, but their global effects remain unknown since 2008, the last date of a comprehensive review of prior studies.

AIMS

This study aims at evaluating the efficacy of interventions to promote sexual health, reduce STIs and unplanned pregnancies targeted to adolescents available after 2008; and analyzing the moderators of their global efficacy.

METHODS

We searched electronic databases and manual searches of some journals focused on STIs in May 2016. The studies evaluated the efficacy of interventions to reduce sexual risk in adolescents (age range: 11-19) anywhere in the world. Effect size of the relevant outcomes for sexual risk was calculated for every study. Analyses incorporated random-effect assumptions for each outcome. The homogeneity in the results was examined with the I2 statistic and its associated 95% confident interval.

RESULTS

Data from 63 studies (59,795 participants) were analyzed for behavioral and non-behavioral outcomes. In the short term, interventions had a positive impact in sexual health-related knowledge (Hedges'g = 1.01), attitudes (g = 0.29), self-efficacy toward condom use (g = 0.22), intention to refuse sex (g = 0.56), condom use intention (g = 0.46), and condom use (g = 0.38). In the medium term, positive effects observed at the short-term were maintained, although effect size significantly decreased in all variables. In the long term, interventions improved condom use (g = 0.47). Moderators of the efficacy are discussed.

CONCLUSIONS

Sexual health promotion interventions are effective to promote sexual health through increasing condom use. Effects on non-behavioral variables tend to decrease over time, while condom use increased in the long-term. Interventions should focus on the long-term efficacy, especially in behavioral and biological measures.

Structural Interventions in HIV Prevention: A Taxonomy and Descriptive Systematic Review

One of the four national HIV prevention goals is to incorporate combinations of effective, evidence-based approaches to prevent HIV infection. In fields of public health, techniques that alter environment and affect choice options are effective. Structural approaches may be effective in preventing HIV infection. Existing frameworks for structural interventions were lacking in breadth and/or depth. We conducted a systematic review and searched CDC's HIV/AIDS Prevention Research Synthesis Project's database for relevant interventions during 1988-2013. We used an iterative process to develop the taxonomy. We identified 213 structural interventions: Access (65%), Policy/Procedure (32%), Mass Media (29%), Physical Structure (27%), Capacity Building (24%), Community Mobilization (9%), and Social Determinants of Health (8%). Forty percent targeted high-risk populations (e.g., people who inject drugs [12%]). This paper describes a comprehensive, well-defined taxonomy of structural interventions with 7 categories and 20 subcategories. The taxonomy accommodated all interventions identified.
