Introduction: Nutritional requirements increase during lactation. However, maternal dietary intakes of Malaysian mothers are subjected to restrictions commonly included in traditional postpartum practices. This study aimed to assess the maternal dietary intake status during the recommended six month exclusive breastfeeding (part of which included the traditional confinement) period. Methods: Thirty-two Malay mothers aged 18-35 years, who had delivered full-term (at ≥37 weeks) singleton babies and were exclusively breastfeeding, were included in the study. Maternal dietary intake was assessed using multiple-pass diet recall on Days 10, 30, 60, 90, 120, 150, and 180, postpartum. The average total energy and macronutrient intakes were compared against recommended values. Results: The findings of this study demonstrated that maternal intakes of total energy ranged from 1,500-2,000kcal/day, carbohydrate 189-272g/day, protein 58-72g/day, and total fat 32-70g/day. Total calorie intake was the lowest during confinement period (Days 10 and 30) compared to the rest of the exclusive breastfeeding period. This is similar with total fat consumption. On the other hand, protein intake was the highest during confinement period whereas carbohydrate intake was consistent throughout the six-month period. Despite the increased requirements, intakes of total calories, protein, total fat, dietary fibre, and water, did not meet the recommended values throughout the exclusive breastfeeding period. Conclusion: Mothers’ inability to fulfil their nutritional requirements during exclusive breastfeeding period may be associated with traditional postpartum dietary practices. Dietary advice with consideration for cultural food taboos practiced by local mothers during confinement may help to improve maternal nutritional intakes during this crucial time.
Maternal diet

Introduction: This study aimed to determine the relationship of maternal dietary intake with human milk nutritional composition, among Malay mothers during the postpartum period of exclusive breastfeeding. Methods: Human milk samples (20- 30ml) were collected from mothers (n=32) at least once monthly for six months postpartum. Macronutrients and fatty acids contents were determined using proximate analysis and gas chromatography methods, respectively. Maternal dietary intakes were recorded using the multiple-pass diet recall method prior to each milk sampling and were analysed using the Nutritionist ProTM software. Associations between the milk composition and maternal diet were tested using Spearman correlation. Results: The energy content ranged between 49.6-59.2 kcal/100ml, protein 1.3-1.4 g/100ml, carbohydrate 6.5-9.7 g/100ml and total fat 6.5-9.7 g/100ml. The polyunsaturated, monounsaturated, and saturated fatty acids concentrations were 10.5-19.1 %, 40.6-43.5 %, and 38.0-49.7 %, respectively. During confinement (first month postpartum), total energy and total fat content of human milk were the highest whereas total carbohydrate was the lowest, compared to the rest of the exclusive breastfeeding period. In contrast, intakes of total calorie and total fat were the lowest, whereas protein was the highest during this period. However, no associations were detected between human milk nutritional contents and maternal dietary intake. Conclusion: In our study population, the composition of maternal diet and nutritional content of human milk differed between confinement and post-confinement periods. However, the association between maternal diet and human milk composition itself warrants further investigation.
