Caregivers play a vital role in ensuring that the complementary feeding transition and beyond happens optimally to achieve normal growth and development in their children. Objective: The aim was to explore what factors influenced the primary caregivers’ choices during the complementary feeding transition period. Methods: A cross-sectional qualitative study was conducted using focus-group discussions and interviews with caregivers of children enrolled in the Optimal Child Growth and Development (OrCHID) study, which included participants from the Mother and Child in Environment (MACE) cohort and SONKE mother and child cohort. Results: During the analysis of the focus-group discussions (FGDs) and interviews, nine themes were identified including: (i) starting complementary feeding; (ii) food choices; (iii) family meals; (iv) food preparation methods; (v) meal composition; (vi) texture; (vii) education source; (viii) food source; and (ix) nutrition knowledge. These themes and the key concepts associated with them were categorised into timing and transition, meal preparation, and knowledge and choices. Conclusion: The caregivers relied largely on advice from family members who advised on their customs and cultural belief systems, which then impacted when the caregivers started complementary foods, food choices, texture, meal composition and transition to family meals. The caregivers sourced complementary foods based on accessibility, convenience and affordability. The caregivers described having a responsive feeding style, where their decisions were influenced by their sensitivity to how their child was responding emotionally and/or physically to the foods they were receiving.

Recent literature has proposed less restrictive dietary guidelines in CKD to improve dietary adherence and outcomes; however, limited evidence of its implementation exists. Objectives: This study (trial number: PACTR202002892187265) investigated the effect of simplified dietary advice on nutritional outcomes and adherence after four weeks of dietary advice. Design: A before-and-after study was conducted. Outcome measures: Sociodemographic, clinical and biochemical information was collected and anthropometric measurements performed on Stage 3–5 CKD participants attending a pre-dialysis clinic. Uremic toxins were quantified by UPLC/fluorescence detection. Dietary intake was assessed using a quantified food frequency questionnaire (QFFQ). Participants were educated by the study dietitian on simplified dietary advice using an infographic. A diet-adherence score sheet monitored adherence. All outcomes were measured at baseline and four weeks after the diet was advised. IBM SPSS® version 27 was used for statistical analysis. Results: Fifty-nine participants, mean age 41.0 ± 11.6 years, completed the study. After four weeks, significant improvements were found in body mass index (p < 0.006), waist circumference (p < 0.001), mid-upper arm circumference (P < 0.001), serum total cholesterol (p < 0.045), serum triglycerides (p < 0.017), energy (p < 0.001), protein (p< 0.001) and most dietary intake variables. Overweight and obesity prevalence was high at 68%. Uremic toxin concentrations remained stable. Dietary adherence was 88.6%. Conclusion: The simplified dietary advice suggests improved nutritional outcomes in CKD patients who were predominantly overweight and obese, without compromising kidney function. This study highlights the importance and feasibility of simplified nutrition education in CKD.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"168 - 176"},"PeriodicalIF":1.1,"publicationDate":"2022-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45586472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design: An experimental, non-equivalent control group intervention study design was used in a 104 purposively selected sample. Two groups were compared: hyperhomocysteinaemic (hyperHcy) (n = 61) and normo-homocysteinaemic (normoHcy) (n = 43). Setting: Elders attending a day-care centre in Sharpeville, Gauteng, South Africa. Subjects: All subjects were equivalent in age (> 60 years), race (black) and unemployed/pensioner. Outcome measures: The following parameters were determined at baseline and after the six-month supplementation: serum Hcy, vitamins B6, B12 and folate levels, red cell count, mean cell volume, haemoglobin, haematocrit and the nutritional intake of vitamin B6, B12 and folate. Results: A very high incidence (66.36%) of hyperhomocysteinaemia was present in the sample. The mean ± standard deviation (SD) serum Hcy level in hyperhomocysteinaemic individuals decreased statistically significantly from 25.00 ± 8.00 umol/l to 18.80 ± 12.00 umol/l after the intervention. The number of respondents with an increased Hcy level decreased from 100% (baseline) to 67% after the intervention. Conclusions: It is concluded that supplementation of vitamins B6, B12 and folate is an effective Hcy-lowering approach to reduce hyperhomocysteinaemia in an elderly population, and thereby reduce their risk of cardiovascular disease (CVD). Summary The supplementation had a beneficial effect on the respondents’ serum vitamin B6 as well as their haemopoiesis (decreased macrocytosis).","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"162 - 167"},"PeriodicalIF":1.1,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45916509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Thirty-one of the biggest fast-food restaurants in South Africa were included to estimate the proportion of those that provided nutritional information on their websites/outlets. Energy, protein, fat, carbohydrate, salt and sugar nutrient compositions were compared for similar food items (burger or pizza), and a meal combination that included burger/pizza, medium-size fried chips and a sugar-sweetened beverage. The UK Traffic Light labelling system was used to compare fat, salt and sugar across restaurants. Results: Only 58% of the restaurants provided some form of nutritional information. While all burgers were high in protein, some were also high in fat, salt and sugar, as indicated by percentages of the nutritional reference ranges above 30%. Similarly, this was the case for pizzas. All meal combinations particularly exceeded the total recommended energy, carbohydrates, sugar and salt content, and most also exceeded the recommended fat content. Conclusions: Consumption of popular South African fast foods may disproportionally contribute to the daily intakes of total energy, fat, salt and sugar, especially when consumed as combination meals including fried chips and sugar-sweetened beverages. Recommendations: Consumers should limit their fast-food intake and avoid eating meal combinations. The South African Government’s commitment to curb the rise of non-communicable diseases should consider regulations that mandate nutritional labelling of fast foods, to assist consumers in making informed dietary choices.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"155 - 161"},"PeriodicalIF":1.1,"publicationDate":"2021-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44163914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It contributes to under-five mortality but is also largely a preventable disease. Objective: This study aimed to assess the prevalence of and mortality associated with SAM. Design: A retrospective review of hospital files was conducted. Setting: Dora Nginza Hospital, Eastern Cape, South Africa was the site of the study. Subjects: The study included children from 6 to 59 months of age admitted to the paediatric ward between January 1, 2018 and December 31, 2018. Children with chronic disease were excluded. Ethics approval was granted by Walter Sisulu University (053/2019). Outcome measures: Anthropometric, co-morbid and outcomes data were retrieved and analysed. Results: A total of 1 296 children were included in the study, 93 with SAM. The prevalence of SAM was 7.2%. Children with SAM had a median age of 16 months (IQR 11–25). Gender distribution was 52 (56%) females and 41 (44%) males. The inpatient mortality rate for children with SAM was 6.5%. Children with SAM were at significantly increased risk of mortality (RR 5.97, 95% CI 3.1–11.6, p-value < 0.0005). Three factors were significantly associated with mortality: nutritional oedema, sepsis, and hypokalaemia. Conclusion: The prevalence of SAM at Dora Nginza Hospital is high, and children with SAM are at significantly increased risk of mortality. Specific risk factors for mortality include sepsis, urinary tract infection, nutritional oedema and hypokalaemia. Modifiable factors associated with SAM and SAM-related mortality need to be targeted urgently to improve outcomes.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"149 - 154"},"PeriodicalIF":1.1,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48295484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Outcome: Dietary intake data from multiple-day weighed food records were analysed on nutrient, food group and meal and snacking pattern levels. Results: Recorded energy intakes of participants (n = 105 first years, n = 166 third years; response rate: 73.6%) were below Estimated Energy Requirements. Across year groups, intakes exceeded and fell below the Acceptable Macronutrient Distribution Range for fat and carbohydrates respectively; however, third years consumed cereals, grains and starchy vegetables more often. Over 50% of first and third years exceeded Estimated Average Requirements of respectively 3 and 6 of 10 tested micronutrients. Third years recorded higher (all p < 0.001) intakes of protein, magnesium, calcium, zinc and vitamin A than first years. Similarly, their Nutrient Adequacy Ratios were higher (all p < 0.001) for magnesium, calcium and vitamins A, B6 and B12. Average Mean Adequacy Ratios were 70% (first years) and 77% (third years). The year groups differed in terms of food group intake. The number of daily eating occasions decreased over weekends for first and third year students, yet intakes of energy (p < 0.05) and fat (p < 0.001) were higher over weekends.

Design: A cross-sectional, descriptive study was undertaken using a mixed-methods approach. Setting and subjects: Rural and urban primary caregivers of children (one to five years old) were recruited if they had resided in the Blue Crane Route (Eastern Cape) for at least six months. Purposefully selected key informants (KIs) involved in nutrition and food security, health or governance participated in in-depth interviews. Outcome measures: Primary caregivers responded to interviewer-administered questionnaires (IAQ) (N = 161), which investigated various indicators supporting the realisation of the RtF. Statistical analysis of quantitative data examined relationships between urban and rural participants. Significance was considered at p < 0.05. In-depth interviews with key informants (KIs) examined the perceptions of 11 prominent community leaders. Qualitative data were coded deductively and common themes identified. Results: Based on the IAQ, half (51%) of the caregivers had experienced risk of, or food insecurity in the past month. Common themes indicative of suboptimal realisation of the RtF included insufficient employment opportunities, inadequate policies and programme implementation, and inadequate agrarian practices, while the child support grant partially supported the realisation of the RtF. Caregivers felt disempowered by a sense of inability to realise the right themselves without government assistance but KIs suggested that caregivers needed to take responsibility. Conclusion: The RtF of children and their caregivers is not fully realised in the Blue Crane Route. Concerted, multidisciplinary approaches using a rights-based approach to implement policies and programmes are needed, together with the empowerment of the community with necessary skills and resources to further the realisation of the RtF.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"122 - 132"},"PeriodicalIF":1.1,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43232972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
