Infant nutrition during the first 1000 days of life strongly influences future health outcomes. Although the World Health Organization recommends exclusive breastfeeding for the first six months, adherence varies widely across sub-Saharan Africa. A cross-sectional study protocol has been designed to assess how early nutrition and feeding practices relate to cardiovascular risk among infants aged three to nine months in South Africa and Tanzania. Researchers plan to gather sociodemographic details, dietary information, anthropometric measurements, and blood pressure readings. Spot urine samples will be tested for nitric oxide, urine-creatinine ratio, and 8-hydroxy-2'-deoxyguanosine concentrations. In addition, homemade food samples from mothers will undergo macronutrient analysis. Statistical methods will evaluate regional differences and associations, aiming to generate evidence to guide infant nutrition policy across the region.
Early nutrition plays a critical role in long-term health, yet breastfeeding and weaning practices vary substantially across African countries. Establishing clear links between early diet and cardiovascular risk markers helps healthcare providers and policymakers design targeted nutritional guidance, ultimately helping prevent chronic diseases later in life.
This work represents early-stage epidemiological research rather than a commercial technology. The findings could eventually inform public health programmes, nutritional guideline formulation by health authorities, or the future development of fortified complementary infant foods by nutrition manufacturers. However, the abstract does not indicate any direct application pathway or near-market product.

Infant nutrition, especially during the first 1000 days of life, is an important determinant of future health outcomes. The World Health Organization (WHO) recommends exclusive breastfeeding (EBF) in the first six months of life, though the prevalence of EBF varies greatly in the sub-Saharan African (SSA) region. The aim of this study is to determine how infant nutrition and feeding practices may be linked to cardiovascular risk in South Africa and Tanzania. This cross-sectional study will recruit 3-9-month-old infants. Data collected will include sociodemographic and nutrition information, weight, height, mid-upper arm circumference (MUAC), head circumference, blood pressure and spot urine samples for determination of urine-creatinine ratio, 8-Hydroxy-2’-deoxyguanosine and nitric oxide concentrations. Home-made food samples will be collected from the mothers of infants for macronutrient content analysis. SPSS will be used for statistical analysis, such as frequency, proportion, means, t-tests, ANOVA, and logistic regression, to assess associations and regional variations. This will be the first prospective study to assess the impact of infant nutrition and feeding habits on cardiovascular risk in infants in two SSA countries, which will be useful for advising policy on infant nutrition.
