Malaria Risk and Prevention in Asian Migrants to Angola

The number of Asian migrants working in sub-Saharan developing countries like Angola has been increasing. Their malaria risk, prevention, and care-seeking practices have not been characterized. A cross-sectional survey was conducted in 733 Chinese and Southeast Asian migrants in Angola. Respondents were interviewed and provided blood samples. Samples were analyzed to detect Plasmodium antigen and characterize host anti-Plasmodium response. Positive samples were genotyped using the pfs47 marker. Most respondents (72%; 95% CI: 68-75) reported using bed nets, but less than 1% reported using chemoprophylaxis. Depending on the assay, 1-4% of respondents had evidence of active malaria infection. By contrast, 55% (95% CI: 52-59) were seropositive for Plasmodium antibodies. Most infections were Plasmodium falciparum, but infection and/or exposure to Plasmodium vivax and Plasmodium malariae was also detected. Seroprevalence by time in Angola showed most exposure occurred locally. One respondent had sufficiently high parasitemia for pfs47 genotyping, which showed that the infection was likely locally acquired despite recent travel to home country. Asian migrants to Angola are at substantial risk of malaria. Employers should consider enhanced malaria prevention programs, including chemoprophylaxis; embassies should encourage prevention practices. Angolan healthcare workers should be aware of high malaria exposure in Asian migrants.

Do perceived contraception attitudes influence abortion stigma? Evidence from Luanda, Angola

Abortion stigma is influenced by a variety of factors. Previous research has documented a range of contributors to stigma, but the influence of perceived social norms about contraception has not been significantly investigated. This study assesses the influence of perceived social norms about contraception on abortion stigma among women in Luanda, Angola. This analysis uses data from the 2012 Angolan Community Family Planning Survey. Researchers employed multi-stage random sampling to collect demographic, social, and reproductive information from a representative sample of Luandan women aged 15-49. Researchers analyzed data from 1469 respondents using chi-square and multiple logistic regression. Researchers analyzed women's perceptions of how their partners, friends, communities, and the media perceived contraception, and examined associations between those perceptions and respondents' abortion stigma. Stigma was approximated by likelihood to help someone get an abortion, likelihood to help someone who needed medical attention after an abortion, and likelihood to avoid disclosing abortion experience. Higher levels of partner engagement in family planning discussion were associated with increased stigma on two of the three outcome measures, while higher levels of partner support of contraception were associated with decreased stigma. Perceived community acceptance of family planning and media discussion of family planning were associated with a decrease in likelihood to help someone receive an abortion. These results suggest that increasing partner support of family planning may be one strategy to help reduce abortion stigma. Results also suggest that some abortion stigma in Angola stems not from abortion itself, but rather from judgment about socially unacceptable pregnancies.

Partner Support for Family Planning and Modern Contraceptive Use in Luanda, Angola

Husband's/partner's support for family planning may influence a women's modern contraceptive use. Socio-demographic factors, couple communication about family planning, and fertility preferences are known to play a role in contraceptive use. We conducted logistic regression analysis to investigate the relationship between perceived husband's/partner's approval and husband's/partner's encouragement of modern contraceptive use, adjusting for socio-demographic factors and recent couple communication about family planning. We also examined mediating roles potentially played by perceived contraceptive accessibility and contraceptive self-efficacy (using index created by principal component analysis). Perceived husband's/partner's approval was associated with triple the odds of women's modern contraceptive use and remained significantly associated with 1.6 times the odds, after controlling for contraceptive accessibility and contraceptive self-efficacy. Husband's/partner's encouragement, while initially significantly associated with contraceptive use, became non-significant after adjustments for socio-demographic factors and couple communication. Perceived husband's/partner's approval, separate from a woman's sense of self-efficacy and perceived accessibility of contraceptives, appears strongly and positively associated with current modern contraceptive use. Increased couple communication may help women identify their husband's/partner's approval. Difference between the meaning of approval and encouragement should be explored. Interventions involving information education and communication campaigns geared to men and promoting male involvement in family planning could increase contraceptive prevalence.

Women's Limited Choice and Availability of Modern Contraception at Retail Outlets and Public-Sector Facilities in Luanda, Angola, 2012-2015

In Angola, many women want to use family planning but lack access to affordable and preferred methods. This article assesses the link between women's choice and availability of contraceptive methods in Luanda, Angola, drawing on data from 3 surveys: a 2012 survey among women ages 15-49 and 2 retail surveys conducted in 2014 and 2015 among outlets and facilities offering contraceptive methods. Descriptive statistics for women's contraceptive knowledge, use, and preferred methods were stratified by age group. We report the percentage of establishments offering different methods and brands of modern contraception, and the mean price, volume of units sold, and value (Angolan Kwanzas) for each brand. Data from the 2 retail surveys are compared to measure changes in availability over time. Results show that 51% of women reported having an unwanted pregnancy. Less than 40% of women knew about long-acting reversible contraceptives (LARCs). Overall, the method most commonly used was male condoms (32.1%), with a substantial proportion (17.3%) of women not using their preferred contraceptive. Trends in contraceptive use mirror availability: in 2015, condoms were available in 73.6% of outlets/facilities, while LARC methods were available in less than 10%. The availability of different methods also dropped significantly between 2014 and 2015-by up to 15 percentage points-with a subsequent price increase in many brands. To meet women's needs for contraception and make informed choice possible, Angola should reinforce demand creation and contraceptive supply in both the public and private sectors through behavior change programs aimed at both women and providers, improved quality of services, training of health personnel on method options and delivery, and improved supply chain distribution of contraceptives. This will allow women to find the methods and brands that best suit their needs, preferences, and ability to pay.

Varying family planning strategies across age categories: differences in factors associated with current modern contraceptive use among youth and adult women in Luanda, Angola

Background

The objective of this study is to identify factors associated with current modern contraceptive use among Angolan women. By differentiating according to age groups (15–24 and 25–49 years), this study aimed to help family planning program planners better tailor interventions to improve utilization of modern contraception.

Methods

A household survey was used to collect data from 1,545 women of reproductive age living in Luanda Province, Angola. Data on sociodemographic characteristics, reproductive behavior and intentions, contraceptive knowledge and use, and attitudes and beliefs regarding contraception and abortion were collected. The analyses were stratified based on age: 15–24 years (youth) and 25–49 years (adult). Multivariate logistic regression models were built for each age group, adding different subsets of variables in groups to see how relationships changed across the models.

Results

Common factors associated with modern contraceptive use among all ages include education level, perceived contraceptive accessibility, contraceptive knowledge, communication with partner about family planning in last year, and self-efficacy. Exposure to family planning information in the media in the last few months, perceived partner approval of family planning, and marital status were all positively associated with current modern contraceptive use among women aged 15–24 years. Meanwhile, receiving information about family planning from a pharmacy in the last year was uniquely associated with current modern contraceptive use among women aged 25–49 years.

Conclusion

Young women in Luanda, Angola seem to have a unique set of factors affecting their contraceptive use. These findings highlight the need for family planning programs to cater services and messages toward specific age groups.

Effectiveness of Behavior Change Communications for Reducing Transmission Risks Among People Living with HIV in 6 Countries in Central America

This first region-wide study (N = 2,818) aims to estimate prevalence of HIV-related risks (sexual behavior, HIV disclosure, number of sex partners, violence) and factors associated with these risks as well as evaluate a behavior change communications program targeted to PLHIV in 6 countries in Central America. After 2 years, the program achieved moderate coverage, with 21 % of the sample reporting exposure to interpersonal communications (IPC) and 52 % to mass media program components. The odds of condom use, HIV disclosure, and participation in a self-help group increased by 1.4–1.8 times with exposure to mass media. Exposure to IPC increased odds of condom use by 2.7 and participation in self-help groups by 4.4 times. In addition, being in HIV care or taking ART was associated with condom use and HIV-status disclosure. About 30 % experienced physical or sexual violence, and those who did were 4 times less likely to use condoms. Findings suggest that behavioral interventions for PLHIV can reduce HIV-transmission risks and increase access to care.

The effect of HIV-discordance on the sexual lives of gay and bisexual men in Mexico City

Drawing upon 44 in-depth interviews with men in HIV-discordant gay couples (only one man is HIV-positive) in Mexico, I explore whether being aware of the risk of primary infection or re-infection leads to protected sex. The results have policy implications, as the findings show that a significant number of men have participated in unprotected sex. An explanation is that these men perceive unprotected sex as an expression of commitment to their relationship. On the other hand, those who reported always using protection during sex perceive that guarding each other's health provides mutual benefit and shows their commitment to their relationship.

[Condom use by men with non-stable partners in Mexico City]

OBJECTIVE

To analyze the association between sociodemographic variables and condom use during vaginal sexual relationships with non-stable partners.

MATERIAL AND METHODS

Data were taken from a household probability survey on sexual behavior in 1992-1993 in the Mexico City Metropolitan Area. Of the completed survey were obtained 8,068 men of 15 to 60 years of age. 1,535 were selected because they reported that their last sexual relationship with vaginal intercourse had been with a non-stable partner. Principal component analyses were conducted to groups of variables with common underlying structures, these components and other variables were included in a logistic regressions. Condom use during last intercourse was the dependent variable.

RESULTS

Feeling that sex with condoms or sex without penetration could be pleasurable, a high ranking in a scale on self-efficacy for condom use, compulsion for using a condom because of being afraid of contracting HIV/AIDS were positively associated with using a condom in the last sexual intercourse. Marital status, schooling, and the number of episodes of sexually transmitted diseases were significantly associated with condom use. Perception of inevitability of becoming infected due to lack of trust in condoms was negatively associated with its use. None of the variables regarding knowledge on HIV/AIDS, including means of transmission and ways to prevent its infection, showed any significant association with condom use.

CONCLUSIONS

Even when information is considered important in educational strategies, it might be more important to promote a positive perception on condoms and safe sex as pleasurable (at the individual and social level), as well as the promotion of self-efficacy on being able to use a condom or enforce preventive behaviors against HIV infection.
