RESUMO
INTRODUCTION: Childhood undernutrition is a major public health problem especially in low and middle-income countries (LMIC). The prevalence of early introduction of complementary feeding, low meal frequency, and low dietary diversity are frequent in LMICs. The effect of inappropriate complementary feeding practices on the nutritional status of children is not well documented in East African countries including Tanzania. Therefore, this study aimed at determining the effect of inappropriate complementary feeding practices on the nutritional status of children aged 6-24 months in urban Moshi, Tanzania. METHODOLOGY: A retrospective cohort study was done using the Pasua and Majengo cohorts of mother-child pairs in urban Moshi who were enrolled from 2002 to 2017. About 3355 mother-child pairs were included in the analysis. Appropriate complementary feeding practices were assessed using WHO IYFP indicators such as age at introduction of solid, semi-solid, or soft foods, minimum dietary diversity, and minimum meal frequency. Nutritional status (stunting, wasting, and underweight) was determined. Multilevel modeling was applied to obtain the effect of inappropriate complementary feeding practices on the nutritional status of children and to account for the clustering effect of mothers and children and the correlation of repeated measures within each child. RESULTS: Majority of the children (91.2%) were given soft/semi-solid/solid foods before six months of age, 40.3percent had low meal frequency, and 74percent had low dietary diversity. Early introduction of complementary food at age 0-1 month was statistically significantly associated with higher risks of wasting and underweight (ARR 2.9, 95%CI 1.3-6.3; and ARR 2.6, 95% CI 1.3-5.1 respectively). Children with low minimum meal frequency had higher risks of stunting, wasting, and underweight (ARR 2.9, 95%CI 2.3-3.6; ARR 1.9, 95%CI 1.5-2.5 and ARR 1.9, 95%CI 1.5-2.4 respectively). Children with low minimum dietary diversity were more likely to be stunted than is the case with their peers who received the minimum dietary diversity (ARR 1.3, 95% CI 1.01-1.6). CONCLUSION: There were a high proportion of children, which were fed inappropriately; Inappropriate complementary feeding practices predisposed children to undernutrition. Our study supports the introduction of complementary feeding, providing minimum dietary diversity, and minimum feeding frequency at six months of age as important in improving the nutritional status of the children.

BACKGROUND: Red meat is an important dietary source of protein and other essential nutrients. Its high intake has been associated with an increased risk of cardiovascular morbidity and mortality, including hypertension (HTN) and hyperlipidaemia (HLP). Despite being physically active, the Maasai at Ngorongoro Conservation Area (NCA) depend heavily on animals' products as their staple food with fewer intakes of vegetables or fruits due to restriction from carrying out agricultural activities within the NCA. This study aimed at determining the prevalence of HTN and HLP and their association with red meat consumption among adult Maasai of NCA. METHODS: A community-based cross-sectional study was conducted in October 2018 using multistage sampling technique. Eight hundred and ninety-four (894) participants enrolled from seven villages in three wards within NCA Data were collected using a modified WHO NCDs-STEPS tool. Anthropometric measurements, blood pressure (BP) measurements, and blood samples for glucose and cholesterol tests were obtained from the study participants. Crude and adjusted prevalence ratio (PR) for factors associated with HTN and HLP were estimated using Ordinal and Bayesian logistic regression models, respectively. RESULTS: The prevalence of HLP was 23.7 percent. The levels were higher among males than were among the females (29.0% vs. 20.1%, p = 0.002). The prevalence of HTN and pre-HTN (elevated BP) were 9.8 and 37.0 percent, respectively. Both HTN and elevated BP were higher among males than were among females (hypertensive [10.9% vs. 9.0%]; elevated BP [44.0% vs. 32.1%], p<0.001). The prevalence of HLP was significantly associated with level II (PR = 1.56, 95%CrI: 1.10-2.09) and level III (PR = 1.64, 95%CrI: 1.08-2.41) of red meat consumption as opposed to level I. CONCLUSION: The prevalence of hyperlipidaemia and elevated BP were high among NCA Maasai. We found a significant association between red meat consumption and hyperlipidaemia. Further follow-up studies are warranted to establish a temporal relationship between red meat consumption and both conditions.
