The effect of maternal anemia on childhood hemoglobin status has received little attention. Thus, we examined the potential association between maternal anemia and childhood anemia (aged 6–59 months) from selected Southern Africa countries. A cross-sectional study using nationally representative samples of children aged 6–59 months from the 2010 Malawi, 2011 Mozambique, 2013 Namibia, and 2010–11 Zimbabwe demographic and health surveys (DHS) was conducted. Generalized linear mixed models (GLMMs) were constructed to test the associations between maternal anemia and childhood anemia, controlling for individual and community sociodemographic covariates. The GLMMs showed that anemic mothers had increased odds of having an anemic child in all four countries; adjusted odds ratio (aOR = 1.69 and 95% confidence interval [CI]:1.37–2.13) in Malawi, (aOR = 1.71; 95% CI: 1.37–2.13) in Mozambique, (aOR = 1.55; 95% CI: 1.08–2.22) in Namibia, and (aOR = 1.52; 95% CI: 1.25–1.84) in Zimbabwe. Furthermore, the odds of having an anemic child was higher in communities with a low percentage of anemic mothers (aOR = 1.52; 95% CI: 1.19–1.94) in Mozambique. Despite the long-standing efforts to combat childhood anemia, the burden of this condition is still rampant and remains a significant problem in Southern Africa. Thus, public health strategies aimed at reducing childhood anemia should focus more on addressing infections, and micronutrient deficiencies both at individual and community levels in Southern Africa.

Despite consistent evidence showing the importance of exclusive breastfeeding (EBF) for six months, it remains a sub-optimal practice in The Gambia. This study aimed at investigating the determinants of EBF knowledge and intention to or practice of EBF. A cross-sectional study was conducted among 334 women receiving care at the Edward Francis Small Teaching Hospital (EFSTH) from December 2015 to February 2016. Using a structured interviewer-administered questionnaire, knowledge on EBF was determined and scored. Participants scoring above or equal to the median were determined to have sufficient EBF knowledge. Multivariate logistic regression analyses were used to identify predictors of EBF knowledge and intention to or practice of exclusive breastfeeding. The proportion of women with sufficient exclusive breastfeeding knowledge and intended to or practice EBF were 60.2% and 38.6% respectively, while only 34.4% received EBF counseling. Earning ≥1500 GMD monthly (Adjusted Odds Ratio [aOR] 1.98; 95% Confidence Interval [Cl] 1.24, 3.16), having positive attitude (aOR 2.40; 95% Cl 1.40, 4.10) and partner supporting EBF (aOR 2.18; 95% Cl 1.23, 3.87) predicted sufficient EBF knowledge. Mothers aged 26–34 years (aOR 0.50; 9 5% Cl 0.31, 0.82) and EBF counseling (aOR 2.68; 95% Cl 1.68, 4.29) significantly associated with intention to or practice of exclusive breastfeeding. In conclusion, improving EBF rates will, therefore, require improved access to information on EBF targeting low socio-economically disadvantaged and older mothers. In addition, emphasis on strengthening the ongoing EBF counseling already within the health system is required.

Although intimate partner violence (IPV) against women is prevalent in sub-Saharan Africa, studies that investigated factors associated with IPV among Gambian women are limited. In this study, we examined the prevalence and factors associated with the different forms of IPV against Gambian women. We used a sample of 3,116 currently married women age (15 ~ 49 years) from The Gambia Demographic and Health Survey 2013. Logistic regression models were used to examine factors associated with Physical Violence (PV), Sexual Violence (SV), and Emotional Violence (EV). Over 40% (n = 1,248) of women reported at least one form of IPV. The prevalence of PV, SV and EV was 20.6%, 4.3%, and 15.1% respectively. Women married at age 18 ~ 24 (adjusted Odds Ratio [aOR]_SV = 1.55), lived with 3 ~ 4 (aOR_PV = 1.69; aOR_EV = 2.10) and ≥5 (aOR_PV = 1.77; aOR_EV = 2.64) children, witnessed parental violence (aOR_PV = 1.66; aOR_SV = 2.75; aOR_EV = 2.25), partner’s primary education (aOR_PV = 1.76), accused of unfaithfulness (aOR_PV = 2.42; aOR_SV = 3.62; aOR_EV4.10), and partner’s alcohol consumption (aOR_PV = 2.56; OR_SV = 3.91; aOR_EV = 2.82) are more likely to report IPV. Conversely, women who lived in Kerewan area (aOR_PV = 0.43; aOR_SV = 0.38; aOR_EV = 0.50), had high income (aOR_PV = 0.65), Wolof (aOR_PV = 0.68) and Jola (aOR_PV = 0.65) ethnicity and unemployed (aOR_PV = 0.59; aOR_SV = 0.56) were less likely to report IPV. Interventions to prevent IPV should focus on education on its effects, and programs that reject sociocultural practices as determinants of IPV.

Overweight and obese women are at risk of pregnancy and delivery complications. This study investigates the trend and association between maternal overweight and obesity on caesarean births in Malawi. We utilised cross-sectional population-based Demographic Health Surveys (DHSs) data collected from mothers aged 18–49 years in 2004/05, 2010, and 2015/16 in Malawi. The outcome measure was caesarian birth within 5 years preceding the surveys. The main independent variable was maternal Body Mass Index (BMI) measured as weight in kilograms by height in meters squared (kg/m2) and categorized according to the World Health Organization (WHO) guidelines. Generalized estimating equations (GEE) regression models were constructed to analyze total samples of 6795, 4474 and 4363 in 2004/05, 2010 and 2015/16 respectively. There was an observed increase in the trend of caesarean births as well as maternal overweight and obesity from 2004 to 2015. The results of the multivariate analyses showed that maternal overweight (adjusted odds ratio [aOR] = 1.35; 95% Confidence Interval [CI] 1.01–1.83) in 2015/16 and (aOR = 1.36; 95% CI: 1.10–1.65) from 2004 to 2015 were risk factors for caesarean births in Malawi. In addition, being obese (aOR = 2.15; 95% CI: 1.12–4.11) in 2004/05, (aOR = 1.66; 95% CI: 1.08–2.55) in 2010, (aOR = 2.18; 95% CI: 1.48–3.21) in 2015/16, and (aOR = 2.16; 95% CI: 1.65–2.84) from 2004 to 2015) increased the risk of caesarean births. In addition, women who had one parity, and lived in the northern region were significantly more likely to have undergone caesarean birth. In order to reduce non-elective cesarean birth in Malawi, specific public health programs should be focus on reducing overweight and obesity among women of reproductive age. More focus attention may be given to women with one parity, particularly in the urban and the northern region of Malawi.

Aim: To investigate the effect of oxidative stress biomarkers on the risk of potentially malignant oral disorders (PMODs). Materials and Methods: A total of 208 male adults with PMODs and an equal number of same-age control patients were enrolled. Plasma biomarkers of oxidative stress, measured with 8-hydroxy-2’-deoxyguanosine (8-OHdG) and 8-isoprostane (8-ISO), were determined using enzyme-linked immunosorbent assay (ELISA) kits. PMODs were diagnosed in accordance with the World Health Organization (WHO) guidelines. Results: A significant association between a high level of 8-ISO and an increased risk of PMODs was identified [odds ratio (OR)=1.71, 95% confidence interval (CI)=1.12-2.63; p=0.013]. This positive association was stronger among patients with PMOD subtype of leukoplakia (OR=1.94, 95% Cl=1.24-3.06; p=0.004). However, no significant association was observed between plasma 8-OHdG levels and overall risk of PMODs or subtypes. Conclusion: Increased plasma 8-ISO levels may indicate the prominence of lipid peroxidation in the development of PMODs, particularly leukoplakia.

Background: We aimed to investigate the association between single-nucleotide polymorphisms (SNP) in mismatch repair (MMR) pathway genes and survival in patients with oral squamous cell carcinoma (OSCC) who received adjuvant concurrent chemoradiotherapy (CCRT). Methods: Using the Sequenom iPLEX MassARRAY system, five SNPs in four major MMR genes were genotyped in 319 patients with OSCC who received CCRT treatment. Kaplan–Meier survival curves and Cox proportional hazard regression models were used to assess overall survival (OS) and disease-free survival (DFS) among MMR genotypes. Results: The results of Kaplan–Meier survival analysis revealed that the MutS homolog 2 (MSH2) rs3732183 polymorphism showed a borderline significant association with DFS (log-rank p = 0.089). Participants with the MSH2 rs3732183 GG genotype exhibited a relatively low risk of recurrence (hazard ratio (HR) = 0.45; 95% confidence interval (CI) = 0.22–0.96; p = 0.039). In addition, the MutL homolog 1 (MLH1) rs1800734 GG genotype carriers exhibited higher OS (HR = 0.52, 95% CI = 0.27–1.01; p = 0.054) and DFS (HR = 0.49, 95% CI = 0.26–0.92; p = 0.028) rates. Conclusions: Our results indicated that the GG genotypes of MSH2 rs3732183 and MLH1 rs1800734 are associated with relatively high survival in OSCC patients treated using adjuvant CCRT. These polymorphisms may serve as prognosis predictors in OSCC patients.
