Acceptance of an orange-fleshed sweet potato complementary food by infant caregivers in KwaZulu-Natal Province ­ a preliminary study

Background. Vitamin A deficiency (VAD) is a major public health problem that affects South African children and is a major contributor to the mortality of children under five years of age. VAD can result in visual impairment, diarrhoea and increased risk of severe measles and death. Orange-fleshed sweet potato (OFSP), a staple crop biofortified with provitamin A, has the potential to improve vitamin A intake in infants, especially when used as a complementary food.Objective. To assess the acceptance of an OFSP complementary food by infant caregivers.Methods. This study was conducted at the Newtown Community Health Centre, Inanda, in the eThekwini District of KwaZulu-Natal (KZN). Sixty-three infant caregivers assessed the acceptance of complementary foods made from OFSP and white-fleshed sweet potato (WFSP) (control), using a five-point hedonic rating test. In addition, ten caregivers participated in two focus group discussions, using pre-determined questions.Results. There were no statistically significant differences in the sensory attribute ratings of complementary foods made from WFSP and OFSP. The OFSP complementary food was well-accepted, especially its colour and soft texture. None of the focus group discussion participants had seen or tasted the OFSP before. Caregivers were willing to buy the OFSP, if it were available and cheaper than the WFSP.Conclusion. The complementary food made from the OFSP was highly acceptable to infant caregivers attending the Newtown Community Health Centre in KZN. It has the potential to be used in complementary feeding and to improve the vitamin A status of infants

Dietary Intake and Metabolic Control of Children with Type 1 Diabetes Mellitus Aged 6-10 Years in KwaZulu-Natal

Objectives: The objective of this study was to assess the dietary intake and metabolic control of children with type 1 diabetes. Design: A cross-sectional observational study was carried out. Subjects: A total of 30 subjects whose ages ranged from six to ten years were included in the study. Setting: The study was conducted at the Paediatric Diabetic Clinics at Grey's Hospital; Pietermaritzburg and Inkosi Albert Luthuli Central Hospital (IALCH); Durban; in KwaZulu-Natal. Outcome measures: Dietary intake was assessed using a three-day dietary record. Metabolic control was assessed using glycosylated haemoglobin (HbA1c). Results: The mean percentage contributions of macronutrients to total energy as determined by the three-day dietary records were as follows: carbohydrate - 52; added sucrose - 2; protein - 16; fat - 32. The mean intakes were similar to the recommendations of the International Society for Pediatric and Adolescent Diabetes (ISPAD) Consensus Guidelines (2002). Micronutrient intake was generally adequate. The mean latest glycosylated haemoglobin (HbA1c) for the sample as at the time of the study was 9.7. Five of the thirty subjects had HbA1c values that were within the recommended levels for children with type 1 diabetes. Conclusions: The macronutrient intake in this sample was found to be similar to the ISPAD Consensus Guidelines (2002) while micronutrient intake was adequate in most cases. Overall the sample had poor metabolic control

Helicobacter pylori infection in peptic ulcer disease: the importance of smoking and ethnicity.

This study was conducted to determine the prevalence of Helicobacter pylori (H. pylori) and its associated factors among patients with peptic ulcer disease in Taiping Hospital. Consecutive peptic ulcer disease patients who had undergone esophagogastro-duodenoscopy were included. The H. pylori status was assessed by the rapid urease test. We excluded those who had active bleeding, a perforated peptic ulcer, severe vomiting, a history of gastric surgery, peptic ulcer disease or renal or liver diseases, carcinoma of the stomach, and recent use of antibiotics or proton pump inhibitors. Socio-demography, H. pylori status, medication history and other relevant clinical data were collected from case notes. A total of 416 subjects were selected, 49.7% were positive and 50.3% were negative for H. pylori infection. There were significant associations between H. pylori and age, ethnicity, smoking status and NSAID usage. However, there were no significant relationships between H. pylori status and gender or type of peptic ulcer. Multiple logistic regression showed that other ethnicities than Malays and smokers had a higher risk of H. pylori. Our prevalence rate was low and the identified risk factors were consistent with previous studies. Ethnic differences may be related to genetic and sociocultural behaviors. Quitting smoking may benefit peptic ulcer patients with H. pylori infection.

Effects of vitamin A supplementation during pregnancy and early lactation on body weight of South African HIV-infected women.

Effects of vitamin A supplementation during pregnancy and early lactation on maternal weight among HIV-1-seropositive South African women were examined. Three hundred twelve HIV-seropositive pregnant women between 28 and 32 weeks gestation were studied as part of a randomized, double-blind, placebo-controlled trial at the King Edward VIII Hospital in Durban, South Africa. Patients were randomized to receive placebo or 5,000 IU of retinyl palmitate and 30 mg of beta-carotene daily during pregnancy. At delivery, patients received placebo or 200,000 IU of retinyl palmitate. The main outcome measures were prenatal and postnatal maternal weight and weight loss at three months after delivery as measured in body mass index (BMI). Supplementation of vitamin A was not associated with improvements in prepartum weight gain but was significantly associated with improved weight retention three to six months after delivery (p = 0.02). The benefit of vitamin A supplementation appeared to be confined to subgroups with baseline CD4+ count < 200 cells/microL and serum retinol 0-20 micrograms/dL. Similar trends were observed in maintenance of postpartum BMI. However, no statistically significant associations were observed. Although there was no benefit of vitamin A supplementation on prepartum weight gain, a benefit on maintenance of postnatal weight was observed. The benefit was highest among those who were vitamin A-deficient or whose CD4+ count was < 200 cells/microL presupplementation. In populations for whom antiretroviral therapy is not readily available or accessible, the finding that vitamin A may improve postpartum weight lends some hope to a relatively inexpensive treatment which could be used for helping ameliorate some weight loss which is common during HIV infection.
