Optimal nutrition and physical activity (PA) are essential to ensure healthy ageing. PA is an integral part of a healthy lifestyle; however; the rate of low PA in the elderly (59.7%) is high in South Africa (SA). Regular PA reduces the risks of chronic diseases, such as diabetes, high blood pressure, heart diseases and cancers. Therefore, this review study aims to gather available information concerning PA and suitable methods to promote PA among the elderly in SA. Lack of environmental support for PA, trainers, PA-educated caregivers, poor knowledge about the recommended level of PA and its benefits, lack of motivation by healthcare providers, poor health and nutritional status, and lack of opportunity for social engagement prevent the elderly from participating in PA. Elderly individuals without any physical challenges should participate in at least 150 minutes of moderate-intensity aerobic PA in a week, or at least 75 minutes per week of vigorous-intensity aerobic PA or an equivalent combination of both types of aerobic PA. It is better to start PA slowly and increase the duration and frequency gradually. Even those who have some disease limitations should try to change their status from ‘inactive or no activity’ to ‘some level of activity’ to enjoy the health benefits of PA. More research and programmes focusing on promotion of PA need to be implemented in order to improve PA among the elderly in SA.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48743369","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}

These problems can have a negative impact on the child’s nutritional intake and little is known about the food preferences and characteristics of food choices. In addition, these difficulties can be exacerbated for children and caregivers living in low- and middle-income countries such as South Africa due to limited access to food, resources and health care. Objectives: The purpose of this study was to determine (1) types of feeding difficulties prevalent in children with ASD, (2) food items that children in South Africa prefer, (3) the relationship between age and ASD severity on food preferences. Method: A cross-sectional quantitative research design was employed using an online questionnaire. There was a total of 40 respondents from different provinces in South Africa. The data were analysed using descriptive statistics as well as multiple linear correlation analysis. Results: The study has identified common feeding difficulties in children with ASD and those being diagnosed as picky eaters in South Africa and compared them with difficulties that were found in the international literature. The study also highlighted the food groups that were preferred by children with ASD, showing a preference for starches and snack items compared with fruits and vegetables. In addition, there were significant correlations between ASD severity and ASD age on food preferences, suggesting that both age and severity may be predictors of food choices made by children with ASD, and highlighted a need for multidisciplinary intervention. Conclusions: This study adds to the existing literature on feeding difficulties in children with ASD but provides additional insights into children living in low- and middle-income countries and can be used to improve appropriate and responsive interventions. This study provides evidence that supports the influence of context and family environment regarding feeding in children with ASD.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45116776","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: A cross-sectional descriptive study was undertaken. Setting: South Africa. Subjects: 17 male apprentice jockeys (mean age 18.8 ± 1.7 years). Outcome measures: Agreement of %BF results determined using predictive equations based on skinfold thickness measurements and bioelectric impedance analysis (BIA) with that of the reference method, euhydrated deuterium dilution (eDD). Results: The mean %BF according to eDD was 9.5 ± 2.8%. The skinfold equations by Slaughter et al.

Conclusion: Regardless of hydration status, the skinfold equation by Slaughter et al. 5 is recommended for jockey apprentices 18 years and younger. For those > 19 years, the hydration state must be confirmed prior to measurement. If euhydrated, the Van Loan et al. 4 BIA equation is recommended and if dehydrated the Durnin and Womersley 1 using either Siri 2 or Brožek et al. 3 is recommended.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/16070658.2021.1940716","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44133870","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: Children who completed a randomised controlled trial were enrolled at age 12 months (n = 392) and followed-up until age 18 months (n = 252; dropout rate 35.7%). Two previously exposed (PE and PE-plus) groups (received SQ-LNS from 6–12 months, but no supplement from 12–18 months) were compared with the delayed intervention (DI) group (received no supplement from 6–12 months, but received SQ-LNS from 12–18 months). Methods and outcome measures: At age 12 and 18 months, weight, length, haemoglobin (Hb) and psychomotor development were measured. Setting: The study was carried out in peri-urban Jouberton area, Klerksdorp, South Africa. Subjects: Children aged 12–18 months. Results: Compared with DI, negative effects (either a trend or statistically significant) were observed for PE and PE-plus for length-for-age Z-scores (LAZ) (p = 0.091 and p = 0.075, respectively), PE-plus for weight-for-age Z-scores (WAZ) (p = 0.027), and PE and PE-plus for Hb (p = 0.080 and p = 0.033, respectively); and a positive effect for PE-plus for eye–hand coordination (p = 0.086). The odds for anaemia were higher for PE-plus compared with DI (OR = 1.68; 95% CI 0.91, 3.09). Regardless of group, prevalence of anaemia and stunting increased from age 12 to age 18 months. Conclusions Benefits of providing SQ-LNS from age 6–12 months were not sustained at age 18 months, compared with providing SQ-LNS from age 12–18 months. Studies to determine the optimum supplementary period to achieve sustainable benefits of SQ-LNS on linear growth and iron status are warranted.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/16070658.2021.1951950","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46923992","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 is important for intervention to be timeous and adopt a team approach, with each professional displaying understanding of both dysphagia and each other’s roles. The nurse is at the epicentre of service provision in hospitals and is ideally positioned to collaborate with the speech-language therapist to manage dysphagia. The state of collaboration, however, is not ideal. Reasons perpetuating this need, to be understood to facilitate improved care by nurses for patients with dysphagia. Design: The aim of the study was to describe the caseload of dysphagia patients seen by nurses, their experiences caring for patients with dysphagia, and nurses’ views on inter-professional training. Setting: A qualitative, exploratory study was conducted with nurses working at two government hospitals in Johannesburg, South Africa. Subjects: An open-ended semi-structured interview was conducted with nine nurses working with adult patients. Descriptive and inductive thematic analysis was used, comparisons were made between the responses, and data were categorised according to emerging themes. Results: Results confirmed that while experience improved care, gaps in dysphagia knowledge, inexperience and contextual challenges adversely impacted efficiency of dysphagia care. Inter-professional training and recognition of nurse intervention positively impacted on interactions with dysphagia. Conclusion: Nurses have a central role in dysphagia care in acute settings.

Screening tools have scarcely been evaluated in the developing world where the burden of malnutrition is greatest. Methods A retrospective study was undertaken of 113 patients admitted to the general paediatric wards at Rahima Moosa Mother and Child Hospital in Johannesburg, South Africa. Children 6 months to 14 years old were screened for malnutrition using anthropometry and correlating WHO z-scores, and retrospectively assessed for nutritional risk using a modified STAMP (mSTAMP). Results The mSTAMP identified additional patients at nutritional risk. The majority (87%) of children with normal anthropometry scored as medium and high risk using the mSTAMP. Weight loss and length of hospital stay (LOS) were higher in medium and high risk groups: One (5%) low risk child lost weight, compared with 8 (38%) medium and 12 (57%) high risk children (p = 0.021). Low risk children had a median LOS of two and half days (IQR 1–8) compared with medium and high risk groups, with medians of three (IQR 3–8) and six (IQR 4–9) days respectively (p = 0.04). Conclusion The mSTAMP identified more children at risk of malnutrition who may not have been considered for nutritional therapy during the hospital stay using anthropometry screening alone. There is a place for nutritional risk screening in developing world settings, but tools may need to be modified locally. Further studies and validation of these tools in sub-Saharan Africa seem prudent and may result in improved nutrition and outcomes of hospitalised children.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/16070658.2021.1940718","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44601516","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}
