This study aimed to examine associations of dietary quality and diversity among reproductive-aged women with overweight and obesity. We conducted a cross-sectional study in the Health and Demographic ...Surveillance System of the Dar es Salaam Urban Cohort Study (DUCS) in Tanzania. A random sample of 1004 non-pregnant women was selected from the DUCS population database and interviewed about dietary information using the FFQ. Women were aged 30.2 (±8.1) years; 27.8% were overweight and 22.6% were obese. All 1004 women in the study consumed starchy staple foods. Of all the women studied, 10.5%, 1.7% and 3.8% consumed vitamin A rich dark green vegetables, nuts and seeds, and beans and peas, respectively. Compared with women in the lowest quintile of Prime Dietary Quality Score (PDQS), those who were in the highest quintile were significantly less likely to be overweight or obese (Adjusted Prevalence Ratio (APR) = 0.76, 95%CI: 0.62, 0.89) (F for trend = 0.029). Dietary diversity score (DDS) was not significantly associated with overweight and obesity. Risk factors included the highest consumption of animal foods (APR = 2.81, 95% CI: 1.51-3.51) and fast food (APR = 2.57, 95% CI: 1.24-4.34). Consumption of legumes and whole grains was associated with lower risk (APR = 0.59; 95% CI: 0.38-0.2). Dietary quality is an important predictor of overweight and obesity among women of reproductive age. Nutrition interventions may be warranted to support women of reproductive age to enter pregnancy with healthier weight to prevent adverse pregnancy outcomes and future risk of chronic diseases.
People who inject drugs (PWID) in Sub-Saharan Africa have limited access to comprehensive HIV services. While it is important to inform programming, knowledge about factors influencing access to ...comprehensive HIV services is scarce. We assessed the proportions of PWID with access to HIV prevention services and associated socio-cognitive factors in Tanzania.
A cross-sectional survey was conducted among PWID between October and December 2017 in Dar es Salaam, Tanzania. Data on access to HIV prevention services, demographics and selected socio-cognitive factors were collected through structured face-to-face interviews. Weighted descriptive and forward selection multivariable logistics regression analyses were done to assess independent associations between HIV prevention services and predictors of interest. The results were two tailed and a p-value of less than 0.05 was considered statistically significant.
The study included 611 PWID (males: 94.4%) with a median age of 34 years (Interquartile Range (IQR), 29-38). A large majority of participants reported to have access to condoms (87.8%), sterile needles/syringes (72.8%) and ever tested for HIV (66.0%). About half (52.0%) reported to have used condoms in the past one month and about a third (28.5%) accessed a peer educator. The odds of testing for HIV decreased among participants who perceived their HIV risk to be high (aOR = 0.29; 95%CI: 0.17-0.49) and those experienced sexual violence (aOR = 0.60; 95%CI 0.37-0.98). However, the odds of testing for HIV increased among participants with secondary level of education (aOR = 2.16; 95%CI: 1.06-5.55), and those who reported having correct comprehensive HIV knowledge (CCHK) (aOR = 1.63; 95%CI 1.12-2.41). The odds of access to condoms increased among females (aOR = 2.23; 95%CI: 1.04-5.02) but decreased among participants with secondary level of education (aOR = 0.41; 95%CI: 0.19-0.84), an income of >TZS 200,000 (aOR = 0.39; 95%CI: 0.23-0.66) and those who perceived their HIV risk to be high (aOR = 0.13; 95%CI: 0.03-0.36). The odds of access to peer educators was higher among participants with primary (aOR = 1.61; 95%CI: 1.01-2.26), and secondary (aOR = 2.71; 95%CI: 1.39-5.33) levels of education. The odds of access to sterile needle and syringe decreased among participants who perceived their HIV risk to be high (aOR = 0.11;95%CI 0.05-0.22), and low-medium (aOR = 0.25;95%CI 0.11-0.52) but increased among those with primary level of education (aOR = 1.72;95%CI 1.06-2.78).
Access to condom, HIV testing, sterile needles and syringes were relatively high among PWID. However, condom use and access to peer educators was relatively low. HIV knowledge and risk perception, gender, education, and sexual violence influenced access to HIV prevention services. There is an urgent need to address the identified socio-cognitive factors and scale up all aspects of HIV prevention services to fast-track attainment of the 2025 UNAIDS goals and ending the HIV epidemic.
Limited studies and differential risk behaviors among men who have sex with men (MSM) in Africa calls for population-specific studies. We present results from the largest integrated biobehavioral ...survey among MSM in Africa to inform programming.
This was a cross-sectional study using respondent-driven sampling to recruit MSM aged 18 and above. Data on sociodemographic characteristics and HIV-related risks were collected and all participants were tested for HIV, herpes simplex virus type-2 (HSV-2), hepatitis-B virus (HBV), and syphilis RESULTS:: A total of 753 MSM with a mean age of 26.5 years participated in the study and 646 (85.7%) provided blood for biological testing. The prevalence of HIV was 22.3%, HSV-2 40.9%, syphilis 1.1%, and HBV 3.25%. Significant risk factors for HIV were age above 25, having no children adjusted odds ratio (aOR), 2.4, 95% confidence interval (CI): 1.4 to 4.2, low HIV-risk perception (aOR, 2.6, 95% CI: 1.2 to 5.3), receptive position (aOR, 8.7, 95% CI: 1.2 to 5.3), and not using water-based lubricants (aOR, 2.6, 95% CI: 1.0 to 4.5) during the last anal sex. Also associated with HIV infection was, having sexual relationships with women (aOR, 8.0, 95% CI: 4.1 to 15.6), engaging in group sex (aOR, 3.8, 95% CI: 1.6 to 8.4), HSV-2 seropositivity (aOR, 4.1, 95% CI: 2.6 to 6.5), and history of genital ulcers (aOR, 4.1, 95% CI: 1.1 to 7.2).
HIV infection and HSV-2 were highly prevalent among MSM. Low perceived HIV risk, practice of risk behaviors, and infection with HSV-2 were significant predictors of HIV infection. Behavioral interventions, HSV-2 suppressive therapies, and pre-exposure prophylaxis are highly needed.
Scaling up of antiretroviral therapy (ART) is currently underway in sub-Saharan Africa including, Tanzania, increasing survival of people living with HIV/AIDS (PLWHA). Programmes pay little attention ...to PLWHA's reproductive health needs. Information on fertility desire and intention would assist in the integration of sexual and reproductive health in routine care and treatment clinics.
A cross-sectional study of all PLWHA aged 15-49 residing in Kahe ward in rural Kilimanjaro Tanzania was conducted. Participants were recruited from the community and a local counselling centre located in the ward. Data on socio-demographic, medical and reproductive characteristics were collected through face-to-face interviews. Data were entered and analysed using STATA statistical software.
A total of 410 PLWHA with a mean age of 34.2 and constituting 264 (64.4%) females participated. Fifty-one per cent reported to be married/cohabiting, 73.9% lived with their partners and 60.5% were sexually active. The rate of unprotected sex was 69.0% with 12.5% of women reporting to be pregnant at the time of the survey. Further biological children were desired by 37.1% of the participants and lifetime fertility intention was 2.4 children. Increased fertility desire was associated with living and having sex with a partner, HIV disclosure, good perceived health status and CD4 count ≥200 cells for both sexes. Reduced desire was associated with havingmore than 2 children among females, divorce or separation, and having a child with the current partner among both males and females.
Fertility desire and intention of PLWHA was substantially high though lower than that of the general population in Tanzania. Practice of unprotected sexual intercourse with higher pregnancy rate was observed. Fertility desire was determined by individual perceived health and socio-family related factors. With increasing ART coverage and subsequent improved quality of life of PLWHA, these findings underscore the importance of integrating reproductive health services in the routine care and treatment of HIV/AIDS worldwide. The results also highlight a group of PLWHA with potentially high desire for children who need to be targeted during care.
Abstract Alcohol consumption in Tanzania exceeds the global average. While sociodemographic difference in alcohol consumption in Tanzania have been studied, the relationship between psycho-cognitive ...phenomena and alcohol consumption has garnered little attention. Our study examines how depressive symptoms and cognitive performance affect alcohol consumption, considering sociodemographic variations. We interviewed 2299 Tanzanian adults, with an average age of 53 years, to assess their alcohol consumption, depressive symptoms, cognitive performance, and sociodemographic characteristics using a zero-inflated negative binomial regression model. The logistic portion of our model revealed that the likelihood alcohol consumption increased by 8.4% (95% confidence interval CI 3.6%, 13.1%, p < 0.001) as depressive symptom severity increased. Conversely, the count portion of the model indicated that with each one-unit increase in the severity of depressive symptoms, the estimated number of drinks decreased by 2.3% (95% CI 0.4%, 4.0%, p = .016). Additionally, the number of drinks consumed decreased by 4.7% (95% CI 1.2%, 8.1%, p = .010) for each increased cognitive score. Men exhibited higher alcohol consumption than women, and Christians tended to consume more than Muslims. These findings suggest that middle-aged and elderly adults in Tanzania tend to consume alcohol when they feel depressed but moderate their drinking habits by leveraging their cognitive abilities.
FFQ are often used to estimate food and nutrient intakes to rank individuals by their level of intake. We evaluated the relative validity of a semi-quantitative FFQ created for use in Tanzania by ...comparing it with two 24 h diet recalls.
We measured relative validity of the FFQ with deattenuated energy-adjusted rank correlations for nutrients, deattenuated rank correlations for food groups, and performed a cross-classification analysis of energy-adjusted nutrient quartiles using percentage of agreement and Bland-Altman analysis.
Interviews were conducted in 2014 in participants' homes in Ukonga, Dar es Salaam, Tanzania.
We surveyed 317 adults aged 40 years or older from the general public.
Deattenuated energy-adjusted rank correlation coefficients of nutrients ranged from -0·03 for riboflavin to 0·41 for percentage of energy from carbohydrates, with a median correlation of 0·21. Coefficients for food groups ranged from 0·00 for root vegetables to 0·51 for alcohol, with a median of 0·35. Relative to the average of the two 24 h diet recalls, the FFQ overestimated energy intake and intakes of all nutrients and food groups, other than tea, with ratios among nutrients ranging from 1·34 for SFA to 7·08 for vitamin A; and among food groups from 0·92 for tea to 9·00 for fruit. The percentage of participants classified into the same nutrient intake quartile ranged from 23 % for SFA to 32 % for both niacin and pantothenic acid, with a median of 28 %.
The FFQ performed moderately well in urban Tanzanian adults.
The Millennium Development Goal No 4 (MDG 4) requires countries to scale up interventions addressing malnutrition and other immediate determinants of burden of disease among children to reduce child ...mortality by two thirds by 2015, which is this year. Whereas globally some achievements have been registered, under-nourishment remains a significant problem in some developing countries such as Tanzania. This study set out to estimate the extent of stunting and its associated determinants to assess the progress made thus far towards achieving MDG 4 in Tanzania.
A random sample of 678 households with under-five children was selected from two randomly selected wards of Kongwa district in Dodoma region, Tanzania. The WHO anthropometric calculator, which computes Z-scores using a reference population, was used to process the anthropometric measurement data taken from all the participants. Children with height for age Z-score of less than 2 were categorised as stunted and coded as 1 and the rest were coded as 0. Proportions of stunting were compared using the chi-square test to determine the association between stunting and the independent variables. Multivariate logistic regression analysis was carried out to determine the Adjusted Odds Ratio (AOR) of the independent determinants of stunting. The cut-off for significant association was set at p = 0.05. All these analyses used the STATA 12 software.
About half (49.7 %) of the children were stunted. This stunting was associated with belonging to households where the head of family was young (<35 years) (AOR = 0.67, 95 % CI 0.47-0.96, p = 0.031), young age of the mothers (AOR = 1.54, 95 % CI 1.06-2.24, p = 0.023), and economic variables such as owning a cellular phone (AOR = 0.66, 96 % CI 0.46-0.94, p = 0.023).
Stunting was highly prevalent in Kongwa district despite general improvements in child nutritional status at the national level. Household characteristics and economic status were found to play a major role in child health. In this regard, disaggregated analyses are therefore important in identifying resilient areas in need of concerted efforts for the MDG 4 to be achieved nationwide.
Health system constraints hamper treatment of children with severe acute malnutrition (SAM) in Tanzania. This non-inferiority quasi-experimental study in Bariadi (intervention) and Maswa (control) ...districts assessed the effectiveness, coverage, and cost-effectiveness of SAM treatment by community health workers (CHWs) compared with outpatient therapeutic care (OTC). We included 154 and 210 children aged 6-59 months with SAM mid-upper arm circumference (MUAC) < 11.5 cm without medical complications in the control and intervention districts, respectively. The primary treatment outcome was cure (MUAC ≥ 12.5 cm). We performed costing analysis from the provider's perspective. The probability of cure was higher in the intervention group (90.5%) than in the control group (75.3%); risk ratio (RR) 1.17; 95% CI 1.05, 1.31 and risk difference (RD) 0.13; 95% CI 0.04, 0.23. SAM treatment coverage was higher in the intervention area (80.9%) than in the control area (41.7%). The cost per child treated was US$146.50 in the intervention group and US$161.62 in the control group and that per child cured was US$161.77 and US$215.49 in the intervention and control groups, respectively. The additional costs per an additional child treated and cured were US$134.40 and US$130.92, respectively. Compared with OTC, treatment of children with uncomplicated SAM by CHWs was effective, increased treatment coverage and was cost-effective.
Objectives Chronic conditions and multimorbidity affect care needs and prevention opportunities. Methods We studied 2,246 men and women aged ≥40 years within the Dar es Salaam Urban Cohort Study from ...June 2017 to July 2018. Seventeen chronic conditions were assessed based on self-report, body and blood pressure measurement, blood tests, and screening instruments. Results Hypertension (51.3%), anemia (34.1%), obesity (32.2%), diabetes (31.6%), depressive symptoms (31.5%), low grip strength (21.2%), and ischemic heart disease (11.9%) were widespread. Multimorbidity was common (73.7%). Women had higher odds of obesity, ischemic heart disease, and high cholesterol (adjusted OR: 2.08–4.16) and lower odds of underweight, low grip strength, alcohol problems, and smoking (adjusted OR: 0.04–0.45). Ten years of age were associated with higher odds of low grip strength, cognitive problems, hypertension, kidney disease, chronic cough, diabetes, high cholesterol, ischemic heart disease, and multimorbidity (adjusted OR: 1.21–1.81) and lower odds of HIV infection (adjusted OR: 0.51). Conclusion We found a higher prevalence of multimorbidity than previously estimated for middle-aged and elderly people in sub-Saharan Africa. The chronic conditions underlying multimorbidity differed by sex.
A nutritious diet is critical to minimizing disease progression of human immunodeficiency virus (HIV) and maximizing treatment efficacy. In low resource settings, meeting the food preference needs of ...people living with the HIV (PLHIV) can be achieved with a supportive food environment when HIV status is disclosed. However, less is known about family-level strategies related to building a supportive food environment. The Diet, Environment, and Choices of positive living (DECIDE), a mixed-methods observational study conducted in peri-urban Dar es Salaam, Tanzania, explored food preferences as influenced by the personal, family, and external food domains.
We completed a qualitative analysis of data generated from 40 interviews (n = 20 PLHIV and n = 20 family members) aimed at exploring the dynamics of food choice for using a family perspective. We expanded on Turner's food environment framework and drew on Giddens' structuration theory to guide our data collection and analysis. Interviews were audio recorded, transcribed, translated from Kiswahili to English, coded, and organized into themes.
We found PLHIV personal food preferences were influenced by organoleptic properties, medications, disease stage, and gender norms. Family members were knowledgeable about the importance of nutritious food for HIV treatment and prioritized these needs to avoid HIV-related stigma and fulfill family obligations. With high prices of nutritious foods (animal source foods, fruits), family members strategized to secure preferred foods for the PLHIV by, 1) forgoing their own food preferences; 2) reallocating food within the household; 3)making food substitutions; and 4) leveraging external networks. These strategies were increasingly employed as the disease progressed.
The use of this expanded framework that included a family perspective on PLHIV food choice illuminated the various households decision-making dynamics that took place in this low resource community. Family members of PLHIV tried to buffer the limitations imposed by the external food environment, especially as the disease progressed. In the context of HIV status disclosure, integrating a family perspective into HIV nutrition interventions and programs has the potential to influence health outcomes and slow disease progression.
