RESUMO
BACKGROUND: Though anecdotal evidence suggests that smoke from HAP has a repellent effect on mosquitoes, very little work has been done to assess the effect of biomass smoke on malaria infection. The study, therefore, sought to investigate the hypothesis that interventions to reduce household biomass smoke may have an unintended consequence of increasing placental malaria or increase malaria infection in the first year of life. METHODS: This provides evidence from a randomized controlled trial among 1414 maternal-infant pairs in the Kintampo North and Kintampo South administrative areas of Ghana. Logistic regression was used to assess the association between study intervention assignment (LPG, Biolite or control) and placental malaria. Finally, an extended Cox model was used to assess the association between study interventions and all episodes of malaria parasitaemia in the first year of infant's life. RESULTS: The prevalence of placental malaria was 24.6%. Out of this, 20.8% were acute infections, 18.7% chronic infections and 60.5% past infections. The study found no statistical significant association between the study interventions and all types of placental malaria (OR = 0.88; 95% CI 0.59-1.30). Of the 1165 infants, 44.6% experienced at least one episode of malaria parasitaemia in the first year of life. The incidence of first and/or only episode of malaria parasitaemia was however found to be similar among the study arms. CONCLUSION: The findings suggest that cookstove interventions for pregnant women and infants, when combined with additional malaria prevention strategies, do not lead to an increased risk of malaria among pregnant women and infants.

Introduction: The correct and consistent use of hormonal contraceptive (HC) methods by sexually active adolescent girls can prevent pregnancy and avert the health and social consequences of unwanted pregnancy for both the mother and her child. Despite these benefits, research shows that HC use is rather low among adolescent girls globally and especially among those in low and middle-income countries. This study was carried out to assess the social-psychological determinants of HC use intentions among adolescent girls and young women. Methods: A cross-sectional survey was conducted among 1,203 young women aged 15-24 years from 70 communities within the Kintampo North Municipality and Kintampo South District in the Bono-East Region of Ghana from April 2021 to September 2021. Multiple linear regression analysis was used to identify factors associated with the intention to use HC among the entire sample of 1,203 respondents and among two sub-samples of young women based on HC use experience. Results: Attitude toward personal HC use (ß = 0.268; p < 0.001), self-efficacy toward access and use of HC (ß = 0.341; p < 0.001), and HC use experience (ß = 0.647; p < 0.001) were found to be significant and unique correlates of HC use intention among the entire sample of adolescent girls. Attitude toward personal HC use and self-efficacy toward access and use of HC were also associated with HC use intention in the two sub samples significantly (p's < 0.001). In addition, among participants with no HC experience, being a Christian as opposed to participants that affiliate themselves with Islam, Traditional religion or being non-religious positively predicts future HC use (ß = 0.230; p < 0.01). Conclusion: Our results demonstrate that different groups of adolescent girls need different interventions, focusing on different determinants for the motivation to use HC. Comprehensive sexuality education, informing all adolescent girls about the personal benefits of HC use and enhancing their skills in accessing and using HCs, can support their HC use intentions to promote their reproductive health and general wellbeing.

RESUMO
BACKGROUND: Adolescent pregnancy remains a public health concern globally. The use of hormonal contraceptive methods are proven ways of preventing pregnancies and in turn unsafe abortions. However, research shows that use of hormonal contraceptive methods is rather low among African adolescent girls, of which Ghana is no exception. OBJECTIVE: This manuscript uses the socio-ecological model to guide our understanding of the factors associated with non-use of hormonal contraceptives among adolescent girls in Ghana. METHODS: An explorative study was done using qualitative data collection methods. Two focus group discussions and sixteen in-depth interviews were conducted among adolescent girls aged 15-19 years (N = 38) in the Kintampo area of Ghana to determine factors affecting uptake of hormonal contraceptives. RESULTS: Adolescents showed a lack of in-depth knowledge related to the different hormonal contraceptive types. Negative attitudes towards adolescent hormonal contraceptive use, fear of real and perceived side effects of hormonal contraceptives, lack of self-efficacy to use contraceptives, fear of disclosure of use and fear of societal stigma related to sexual intercourse and its related issues among adolescents may explain why adolescent girls in this context do not use hormonal contraceptive methods. CONCLUSION: To promote hormonal contraceptives among adolescent girls, a combination of multifaceted social-psychological, personal and community level interventions are needed.
RESUMO
BACKGROUND: Low birth weight and prematurity are important risk factors for death and disability, and may be affected by prenatal exposure to household air pollution (HAP). METHODS: We investigate associations between maternal exposure to carbon monoxide (CO) during pregnancy and birth outcomes (birth weight, birth length, head circumference, gestational age, low birth weight, small for gestational age, and preterm birth) among 1288 live-born infants in the Ghana Randomized Air Pollution and Health Study (GRAPHS). We evaluate whether evidence of malaria during pregnancy, as determined by placental histopathology, modifies these associations. RESULTS: We observed effects of CO on birth weight, birth length, and gestational age that were modified by placental malarial status. Among infants from pregnancies without evidence of placental malaria, each 1 ppm increase in CO was associated with reduced birth weight (-53.4 g [95% CI: -84.8, -21.9 g]), birth length (-0.3 cm [-0.6, -0.1 cm]), gestational age (-1.0 days [-1.8, -0.2 days]), and weight-for-age Z score (-0.08 standard deviations [-0.16, -0.01 standard deviations]). These associations were not observed in pregnancies with evidence of placental malaria. Each 1 ppm increase in maternal exposure to CO was associated with elevated odds of low birth weight (LBW, OR 1.14 [0.97, 1.33]) and small for gestational age (SGA, OR 1.14 [0.98, 1.32]) among all infants. CONCLUSIONS: Even modest reductions in exposure to HAP among pregnant women could yield substantial public health benefits, underscoring a need for interventions to effectively reduce exposure. Adverse associations with HAP were discernible only among those without evidence of placental malaria, a key driver of impaired fetal growth in this malaria-endemic area.

Associations between prenatal household air pollution exposure (HAP), newborn telomere length and early childhood blood pressure are unknown. Methods: Pregnant women were randomized to liquefied petroleum gas (LPG) stove, improved biomass stove or control (traditional, open fire cook stove). HAP was measured by personal carbon monoxide (CO) (n = 97) and fine particulate matter (PM2.5) (n = 60). At birth, cord blood mononuclear cells (CBMCs) were collected for telomere length (TL) analyses. At child age four years, we measured resting blood pressure (BP) (n = 97). We employed multivariable linear regression to determine associations between prenatal HAP and cookstove arm and assessed CBMC relative to TL separately. We then examined associations between CBMC TL and resting BP. Results: Higher prenatal PM2.5 exposure was associated with reduced TL (ß = -4.9% (95% CI -8.6, -0.4), p = 0.03, per 10 ug/m3 increase in PM2.5). Infants born to mothers randomized to the LPG cookstove had longer TL (ß = 55.3% (95% CI 16.2, 109.6), p < 0.01)) compared with control. In all children, shorter TL was associated with higher systolic BP (SBP) (ß = 0.35 mmHg (95% CI 0.001, 0.71), p = 0.05, per 10% decrease in TL). Increased prenatal HAP exposure is associated with shorter TL at birth. Shorter TL at birth is associated with higher age four BP, suggesting that TL at birth may be a biomarker of HAP-associated disease risk.
RESUMO
INTRODUCTION: Tailoring sexual and reproductive health programs and services to the needs of adolescents will help adolescents make informed decisions and choices regarding their sexual and reproductive health. OBJECTIVE: To assess the opinions of service providers on tailoring sexual and reproductive health services to the needs of adolescents. METHOD: A qualitative study using indepth interviews was held among eight decision-makers and service providers in two hospitals within the Kintampo North Municipality and Kintampo South District as well as the Municipal and District Health Directorates in Kintampo North and South between April and May 2011. RESULTS: All respondents expressed the opinion that it is a good idea to tailor sexual and reproductive health services to the needs of adolescents. They admitted that very limited sexual and reproductive health programs targeting adolescent needs were available in the study area. Service providers also reported very low levels of health facilities use by adolescents for sexual and reproductive health information and services. Health professionals attributed the poor sexual and reproductive health services utilization by adolescents to stigma from the society and attitudes of service providers. CONCLUSION: There are no targeted sexual and reproductive health programmes and services for adolescents. Services providers indicated that it is important to tailor sexual and reproductive health services to the needs of adolescents to prevent stigma, unwanted pregnancy, abortion, and sexually transmitted infections.
RESUMO
BACKGROUND: Associations between prenatal household air pollution (HAP) exposure or cookstove intervention to reduce HAP and cord blood mononuclear cell (CBMC) mitochondrial deoxyribonucleic acid copy number (mtDNAcn), an oxidative stress biomarker, are unknown. MATERIALS AND METHODS: Pregnant women were recruited and randomized to one of two cookstove interventions, including a clean-burning liquefied petroleum gas (LPG) stove, or control. Prenatal HAP exposure was determined by serial, personal carbon monoxide (CO) measurements. CBMC mtDNAcn was measured by quantitative polymerase chain reaction. Multivariable linear regression determined associations between prenatal CO and cookstove arm on mtDNAcn. Associations between mtDNAcn and birth outcomes and effect modification by infant sex were explored. RESULTS: LPG users had the lowest CO exposures (p = 0.02 by ANOVA). In boys only, average prenatal CO was inversely associated with mtDNAcn (ß = -14.84, SE = 6.41, p = 0.03, per 1ppm increase in CO). When examined by study arm, LPG cookstove had the opposite effect in all children (LPG ß = 19.34, SE = 9.72, p = 0.049), but especially boys (ß = 30.65, SE = 14.46, p = 0.04), as compared to Control. Increased mtDNAcn was associated with improved birth outcomes. CONCLUSIONS: Increased prenatal HAP exposure reduces CBMC mtDNAcn, suggesting cumulative prenatal oxidative stress injury. An LPG stove intervention may reverse this effect. Boys appear most susceptible.

BACKGROUND: Malaria in pregnancy leads to low birth weight, premature birth, anaemia, and maternal and neonatal mortality. Use of insecticide-treated nets (ITNs) during pregnancy is one of the proven interventions to reduce the malaria burden. However, Ghana has not achieved its target for ITN use among pregnant women. METHODS: A qualitative study was conducted in seven communities purposively selected from the middle belt of Ghana. Participants who had delivered in the six months prior to this study were selected. In all, seven focus group discussions and twenty-four in-depth interviews were conducted between June and August 2010. RESULTS: Respondents knew of the importance of ITNs and other malaria-preventive strategies. Factors such as financial access and missed opportunities of free distribution denied some pregnant women the opportunity to own or use an ITN. Reasons for not using ITNs during pregnancy included discomfort resulting from heat, smell of the net, and difficulty in hanging the net. Participants maintained their ITNs by preventing holes in the nets, retreatment, and infrequent washing. CONCLUSION: Pregnant women know about the causes and prevention of malaria. However, this knowledge is not transformed into practice due to lack of access to ITNs and sleeping discomforts among other logistical constraints.
