The use of linear programming to determine whether breastfed infants can achieve a nutritionally adequate complementary feeding diet: a case study of 6­11-month-old infants from KwaMashu, KwaZulu-Natal, South Africa

Objectives: The objectives of this study were to ascertain whether the nutrient requirements of 6­11-month-old infants can be met with a food-based approach, and to identify the nutrients of which it is difficult to achieve adequate intakes.Design, setting and subjects: A cross-sectional survey and interviews with mothers and caregivers from the KwaMashu Community Health Centre were conducted. One hundred and thirty-four interviews were completed. This information provided the food consumption input for the model using Optifood software. Results: The results revealed that with the current food pattern of infants from the study group in KwaMashu, iron, zinc and calcium are nutrients whose requirements are likely not to be met in the diet. The percentage RNI (recommended nutrient intake) for iron was 25.2%, zinc 51.3% and calcium 77%. Nutrient intakes for these nutrients of concern improved in the 'No pattern' diet but iron and zinc intakes remained below the RNI. According to the best diets modelled by Optifood, it appears that infants in KwaMashu would be able to achieve the recommended intakes of energy, protein, and 8 of the 11micronutrients, as long as breastfeeding on demand continues during the complementary feeding phase. Conclusions: This study calls into question the continued food-based focus to ensure nutrient adequacy in infants. In conjunction with efforts to improve household food security and continued support and promotion of breastfeeding for the first 2 years of life, targeted micronutrient supplementation may be needed to ensure the optimal growth and development of infants in South Africa.

Correlates of exclusive breast feeding among nursing mothers attending child health clinic at a general hospital in Rivers State Nigeria

Background: Early initiation of breast feeding and feeding exclusively for six months have great implication for the survival, well-being and growth of new borne. Factors such as maternal age, occupation, religion, spouse age, spouse occupation, parity, antenatal care (ANC) attendance, mode of delivery (MOD) and birth order are significantly associated with exclusive breast feeding (EBF) Methodology: The study is a descriptive cross-sectional study conducted among nursing mothers attending child health clinic in General Hospital Bonny, in Bonny Island, Rivers State, Nigeria. All eligible nursing mother who presented at the clinic were enlisted for the study. Enlistment of eligible participants was done on every child welfare clinic day. Data was collected using a pretested, interviewer administered, structured questionnaire which was adapted and prepared in English Language. Categorical data was analyzed using multinomial logistic regression model with statistical significance set at 0.05. Result: Results from this study identified significant association between EBF and some maternal variables such as age, occupation and religion. Spouse age and occupation were significantly associated with EBF. ANC attendance, gestational age, MOD, parity and birth order were also significant variables associated with EBF. Conclusion: Maternal variables such as age, occupation, religion, parity, MOD, ANC attendance including spouse age and occupation significantly influence EBF of new borne.
