RESUMO

BACKGROUND: Vitamin A (VA) deficiency (VAD) affects ∼19 million pregnant women worldwide. The extent of VAD in Zambian women of reproductive age is unknown owing to lack of survey inclusion or the use of static serum retinol concentrations, a low-sensitivity biomarker. OBJECTIVES: This cross-sectional study employed isotopic techniques to determine VA status with serum and milk among women aged 18-49 y (n = 197) either lactating with infants aged 0-24 mo or nonlactating with or without infants. METHODS: Assistants were trained and piloted data collection. Demographic data, anthropometry, and relevant histories were obtained including malaria and anemia. For retinol isotope dilution (RID), baseline fasting blood and casual breast milk samples were collected before administration of 2.0 µmol 13C2-retinyl acetate and 24-h dietary recalls. On day 14, blood (n = 144) and milk (n = 66) were collected. Prevalence of total liver VA reserves (TLR) ≤0.10 µmol/g was defined as VAD with comparison to the DRI assumption of 0.07 µmol/g as minimally acceptable for North Americans. RESULTS: When a 20% adjustment for dose lost to milk was made in the RID equation for lactation, mean total body VA stores (TBS) for lactating women were 25% lower than for nonlactating women (P < 0.01), which was not the case without adjustment (P = 0.3). Mean ± SD TLR for all women were 0.15 ± 0.11 µmol/g liver. Using retinol purified from breast milk instead of serum for RID analysis yielded similar TBS and TLR, which were highly correlated between methods (P < 0.0001). Serum retinol ≤0.70 µmol/L had 0% sensitivity using either VAD liver cutoff and milk retinol ≤1.0 µmol/L had 42% sensitivity for VAD at 0.10 µmol/g. CONCLUSIONS: Determining accurate VA status among women of reproductive age, especially lactating women, forms a basis for extrapolation to the general population and informing policy development and program implementation.

RESUMO

BACKGROUND: Iron and Folic Acid are two of the micronutrients recommended for pregnant women to support optimal maternal outcomes with regard to preventing anaemia and foetal birth defects. It is difficult to establish if women provided with iron and folic acid supplementation in Zambia benefit from it and how well it is implemented. The overall objective of this study was to determine the levels of uptake and compliance to iron and folic acid in pregnancy among women of child-bearing age in Zambia, with a focus on both supply and demand factors. METHODS: A cross sectional, mixed method study was done. Data was collected in August and September 2015 from six of the 14 districts in which Scaling Up Nutrition interventions were being undertaken as well as Lusaka district. A household survey covering 402 males and females of child-bearing age, 27 key informant interviews amongst key stakeholders and 12 focus group discussions at community level were conducted. RESULTS: Antenatal clinic attendance was almost universal (98.7%); the majority of both men (92.1%) and women (97.4%) had heard messages about iron and folic acid supplementation; the majority (96.5%) of women reported having taken iron and folic acid tablets during their last pregnancy, with 61.3% starting in the second trimester, 27.2% during the first trimester, and 7.7% in their third trimester. Eighty-five per cent (80.5%) of the women reported that they had taken all the tablets they were given with about 13.4% not taking all the tablets received. CONCLUSIONS: Root cause analysis, using both qualitative and quantitative findings, showed that the main challenges faced were long distances to health facilities and high transport costs; some women not being reached with supplementation messaging; lack of formalised and uniform training around delivery of antenatal messages across health care workers; women not attending antenatal monthly to replenish supplements; and forgetfulness to take the drugs daily. While male involvement may be a supportive factor, it sometimes hinders women from accessing antenatal services. Results showed that both uptake and compliance to iron and folic acid supplementation in pregnancy in Zambia were sub-optimal.

RESUMO

The purpose of this study was to establish best ways of improving household soybean processing and utilization in selected districts in the Eastern Province of Zambia. This was a concurrent triangulation study design, nested with a cross sectional survey and barrier analysis. Up to 1,237 households and 42 key informants participated in the quantitative and qualitative studies respectively. Quantitative data was analysed using Stata MP 15 software (StataCorp, College Station, TX, USA). NVIVO QSR10 software (QSRInt, Melbourne Australia) was used to organize qualitative data which was later analysed thematically. In this study whole soybean processing and utilization in eastern province was at 48%. However, accessibility to soybean for household consumption throughout the year was negligible (0.29%). Based on the food systems an interplay of factors influenced soybean processing and utilization. In the food environment, a ready-made Textured Soya Protein mainly imported [1,030/1237(83%)] and a milled whole soybean-maize blend AOR 816.37; 95%CI 110.83 to 6013.31 were preferred. Reports of labour intensity, hard to cook properties, coarse milling and beany flavour with associated anti-nutrients negatively influenced whole soybean utilization. In the enabling environment, soybean production AOR 4.47; 95%CI 2.82 to 7.08 increased the chances of utilization. Lack of inputs, poor access to affordable credit and lack of ingredients were deleterious to utilization. Low coverage of existing projects and poor access to technologies were other adverse factors. Among the Socioeconomic factors, a higher social hierarchy shown by owning a bed AOR 1.75; 95%CI 1.22 to 2.49, belonging to the Chewa community AOR 1.16; 95%CI 1.08 to 0 1.25, gender of household head particularly male AOR 1.94; 95%CI 1.21 to 3.13, off farm income and livestock ownership were supportive to soybean utilization. Unfavourable factors were; belonging to any of the districts under study AOR 0.76; 95%CI 0.58 to 0.98, lack of knowledge (55.65%), low involvement of the male folks AOR 0.47; 95%CI 0.30 to 0.73 and belonging to a female headed household AOR 1.94; 95%CI 1.21 to 3.13. Age, time and household size constraints as well as unreliable soybean output markets, lack of land, poor soils in some wards and poor soybean value chain governance were other negative factors. Immediately in the food environment there is need to boost milling of whole soybean while strengthening cooking demonstrations, correct processing, incorporation of soybean in the local dishes and conducting acceptability tests. In the enabling environment, there should be access to inputs, affordable credit facilities and subsidized mineral fertilisers. Post-harvest storage, collective action with full scale community involvement and ownership should be heightened. Socioeconomic approaches should target promotion of soybean processing and utilization among all ethnic groups, participation of male folks and female headed households as well as advocating for increased nutrition sensitive social protection. In the medium or long term, capacity building, market development, import substitution agreements, creation of new products, development of cottage industries, information exchange and inter district trade as well as more public-private partnerships and more local private sector players should be bolstered. Lastly farm diversification should be supported.

RESUMO

Objective: The study explored the experiences and challenges of adults living with type 2 diabetes mellitus (T2DM) presenting at the University Teaching Hospital (UTH) in Lusaka. Research design: A qualitative descriptive study was conducted. The research relied on purposive sampling to select 28 participants for in-depth interviews. Participants were interviewed during clinical visits at UTH. Results: Views from participants showed that some adults living with T2DM experienced physical and mental illnesses. Participants' views reflected that their livelihood with T2DM was influenced by family support, poor or non-adherence to treatment guidelines and access to information, education and communication materials. The most important challenges reported were psychosocial and financial. Conclusion: The study concluded that some adults living with T2DM experience a lot of physical sicknesses and their challenges, especially of the psychosocial nature may require professional attention. However, particular attention should be paid to the patient's self-care and psychosocial therapy. Self-care protocols should be tailored to complement the different types of patients with diabetes and improve their quality of life. Cite Now.

RESUMO

Background: The quality of antenatal care (ANC) a woman receives during pregnancy is crucial to both the child and the mother's life. It has been established that providing high-quality ANC can save lives and has a positive impact on postnatal health care services. However, the quality of ANC in Zambia requires attention as maternal and neonatal mortality rates are still unacceptably high with Lusaka district not being left out of the problem. Methods: Using a cross-sectional study design, the main aim of this study was to determine the demand side factors associated with high-quality antenatal care among pregnant women in Lusaka. It also estimated the proportion of women who received high-quality ANC during their last antenatal visit. Multifactorial logistic regression model was fitted in STATA version 13 to predict the demographic, socio and economic factors that influence the quality of ANC. Results: It was established that only 47.1% of pregnant women received high-quality ANC while 52.9% received low quality. Six key ANC interventions were considered, among which urine (36.7%) and blood (46.8%) testing were the least received basic components of ANC. After adjusting for the effect of other factors, women with secondary education had higher odds of receiving high-quality ANC than women with primary level of education (OR = 1.98; 95% CI: 1.24-3.14). Women staying with their husband/partners had lesser odds of receiving high quality ANC compared to those that were not staying with their partners (OR = 0.47; 95% CI: 0.28-0.79). Conclusion: The quality of antenatal care received by pregnant women in Lusaka is low. Continued efforts to improve the delivery of basic ANC services such as blood and urine testing is required to improve the quality of healthcare services provided by medical personnel at all levels.

RESUMO

BACKGROUND: Stunting continues to be a major public health problem globally. Stunting is a manifestation of many factors including inadequate food intake and poor health conditions. However, poor quality nutritional diets during pregnancy, infancy and early childhood lead to inadequate nutrient intake. The prevalence of stunting in Zambia has been over 40% and remains unacceptably high. There is limited information on factors associated with stunting in Zambia. Thus to better understand factors contributing to the high stunting levels, the 2013/14 Zambia Demographic and Health Survey (ZDHS) data was analysed. METHODS: Data was extracted using a data extraction tool and analysed using Stata version 13. Sample data of 12, 328 children aged 0-59 months was analysed. The analysis involved simple and multiple logistic regression to find associations between independent variables and stunting. RESULTS: The prevalence of stunting among under five children in Zambia is 40%. From the 4937 children who were stunted, stunting was higher among male children as compared to female children (42.4 and 37.6% respectively). Additional analysis revealed that children whose source of drinking water was improved (33.7%) were less likely to be stunted compared to children whose source of drinking water was poor (47.7%). Stunting was associated with sex and age of a child; mother's age and education; residence; wealth and duration of breastfeeding. For instance, children whose mothers had higher education showed a 75% reduction of odds compared to children whose mothers had no education (AOR = 0.35, 95%CI: 0.22, 0.54; p < 0.05). Similarly, wealth status showed an inverse relationship. Children who came from rich households showed a 32% reduction of odds compared to children who came from poor households (AOR = 0.68, 95%CI: 0.57, 0.82; p < 0.05). CONCLUSION: The study established that the major predictors of stunting among children under 5 years old in Zambia were sex and age of the child; mother's age and level of education; wealth status; improved source of drinking water; duration of breastfeeding and residence. Therefore, multiple measures targeted at reducing child stunting should be taken in a bid to influence policy and conceiving of programmes.
