“Love, you need to give your child love”: mothers’ perceptions of nurturing care for young children in South Africa
No full textBackground: nurturing care of young children is aimed at promoting lifelong, intergenerational health and well-being, as well as social and economic benefits. This study is aimed at qualitatively exploring maternal perceptions related to nurturing care, their access to information and support for caregiving, the home and community environments and practices, and how caregivers promote infants’ health and well-being in Soweto, South Africa.Methods: the study employed a sequential, two-stage process. First, three focus group discussions were conducted with a total of 19 mothers of children aged 0–24 months, which then informed 12 in-depth interviews (four women from each focus group discussion). Focus group discussions and interviews were audio recorded and transcribed verbatim and data were analysed using thematic analysis.Results: the health and well-being of infants were generally described in relation to their feeding and growth and how physically active they were. The need for pregnancy and caregiving information, accompanied by opportunities to discuss this with a health care worker or other women, was highlighted by participants in this study. Potentially obesogenic and non-responsive infant and young child feeding practices were commonly reported by mothers. Responsive caregiving was described as taking care of children’s physical needs, providing them with love, and playing with them. Female matriarchs were particularly influential in providing caregiving advice and support for mothers. Naturally occurring interactions, such as talking and singing, were commonly reported practices to promote children’s development in the home. Safety concerns were ubiquitous and limited children’s play and exploration outside the home.Conclusions: this is one of few studies to explore caregivers’ perceptions of nurturing care in the South African context and the first to focus specifically on the first 1000 days. Thus, the study findings can contribute to strengthening initiatives to support caregivers to provide nurturing care for young children in South Africa and other similar contexts. Findings point to the need for better targeted information and support for mothers and other caregivers around nurturing care, especially elements related to infant and young child feeding (including responsive feeding), responsive care, early learning, and how to address safety in the home. There is also a gap in the provision of appropriate information and opportunities to engage with peers and health care workers around issues pertinent to pregnant women within current services. These deficiencies can be addressed through strengthening existing services, leveraging current platforms of care and support for pregnant women and young children, particularly through the health system
A maternal "mixed, high sugar" dietary pattern is associated with fetal growth
No full textThis study examined associations between a maternal “mixed, high sugar” dietary pattern during pregnancy and ultrasound‐determined fetal growth in 495 urban African women and explored whether these associations were independent of maternal baseline body mass index (BMI) and gestational weight gain (GWG). Linear mixed effects modelling (LMM) was used to test the associations between maternal mixed, high sugar dietary pattern score, baseline BMI (kg/m2), and GWG (kg/week) and the following fetal growth outcomes: (a) biparietal diameter (cm), (b) head circumference (cm), (c) abdominal circumference (cm), and (d) femur length (cm). In the pooled LMM, a +1 standard deviation (SD) increase in the mixed, high sugar dietary pattern score was associated with higher biparietal diameter (0.03 cm/+1 SD; p = .007), head circumference (0.07 cm/+1 SD; p = .026), abdominal circumference (0.08 cm/+1 SD; p = .038), and femur length (0.02 cm/+1 SD; p = .015). Although these associations were independent of maternal BMI and GWG, higher baseline BMI was independently and positively associated with abdominal circumference (0.03 cm/+1 kg/m2; p = .011) and femur length (0.01 cm/+1 kg/m2; p = .007) and 1 kg/week greater GWG was associated with a 0.82 cm increase in abdominal circumference (p = .007). In urban African settings, where preconception maternal obesity prevalence is high and processed, high sugar diets are common, improving maternal dietary intake and BMI prior to conception should be prioritised for optimising pregnancy and birth outcomes as well as longer‐term offspring health. In addition, dietary management strategies during pregnancy may be beneficial in facilitating healthy fetal growth
A review of adolescent nutrition in South Africa: transforming adolescent lives through nutrition initiative
No full textObjective: In South Africa, urbanisation is associated with substantial burdens of adolescent overweight and obesity, making teenagers vulnerable to longer-term non-communicable diseases. In addition, as potential future parents, the nutritional status of adolescents is increasingly recognised as a key driver of health and well-being in the next generation. This review reported on the available literature examining nutritional status and dietary intakes and practices, as well as their determinants, in South African adolescents. Study design and methods: Medline (Pubmed), Web of Science and EMBASE were searched for relevant articles published between 1994 and May 2018. Applicable search terms and phrases were identified in study titles and/or abstracts and full-text articles were reviewed according to inclusion/exclusion criteria. Data were extracted according to specific review objectives. Results: A total of 67 relevant studies were identified. Only one study used a biochemical marker to describe adolescent nutritional status (vitamin D status; 25(OH)D). Overweight and obesity prevalence increased in South African adolescents over the reference period, with national increases of 6% in boys and 7% in girls between 2002 and 2008. Girls and urban-dwellers were particularly vulnerable to excess adiposity. Dietary intakes demonstrated a transition towards energy-dense, processed foods high in sugar and fat, but low in essential micronutrients. Food choices were driven by the adoption of obesogenic behaviours in the teenage years, including irregular breakfast consumption and fewer family meals, increased snacking and low levels of physical activity. Conclusion: South African adolescents—particularly girls—are increasingly burdened by obesity as a result of urbanisation-associated shifts in dietary intake and eating behaviours. However, the implications for micronutrient status and long-term nutritional health are not known. Additionally, more data on the clustering of diet, activity and sedentary behaviours in adolescent boys and girls is needed, as well as on behaviour patterns to facilitate healthy growth and reduced adiposity.</p
A scoping review of literature describing the nutritional status and diets of adolescents in Côte d’Ivoire
No full textOBJECTIVE: Adolescents living in resource-limited settings remain a neglected population regarding their nutritional health. We reviewed what studies on nutrition have been conducted for adolescents living in Côte d'Ivoire.DESIGN: A scoping literature review, searching for any quantitative studies published from 1 January 2000 to 1 May 2019, referenced in PubMed and grey literature, related to adolescent nutritional status and diet, written in English or French.SETTING: Côte d'Ivoire, West Africa.SUBJECTS: Adolescent girls and boys (aged 10-19 years).RESULTS: We used three search strategies to explore studies related to (1) diet and nutritional practices, (2) anthropometry and (3) micronutrient intakes/status. Each identified 285, 108 and 84 titles and abstracts, respectively, resulting in 384 full-text articles to review. Finally, after adding five relevant studies from the grey literature, thirty articles were included. Two-thirds were cross-sectional observation studies. The main topics were anaemia and parasitic diseases. Among seven intervention studies, most focused on micronutrient supplementation or deworming. No studies on macronutrients or food supplementation were found. Overall, studies showed a high prevalence of undernutrition, along with emerging overweight and obesity. Anaemia and Fe deficiency were highly prevalent, with Fe supplementation showing modest improvements. Malaria and gut parasite infections remain a major burden, affecting adolescents' nutritional status.CONCLUSIONS: Few specific relevant studies have been published regarding adolescent nutrition in Côte d'Ivoire, and most studies being focused on younger children. There are knowledge gaps about many nutritional aspects in this population, which urgently need to be addressed.</p
The relationships between socioeconomic status, dietary knowledge and patterns, and physical activity with adiposity in urban South African women
No full textBackground: This cross-sectional study examined the relationship between socioeconomic status (SES), dietary knowledge and patterns, and physical activity level with body mass index of urban South African young women. Methods: Data were collected on 160 black South African women (aged 18–24 years) and included household SES, food frequency and nutritional knowledge questionnaires, self-reported physical activity and anthropometry. To assess household SES index, 1–7 assets were categorised as a lower household SES and those with 8–13 assets as a higher household SES. Structural equation modelling analysis was used to determine the direct, indirect and total effects on adiposity of household SES, age, education, nutrition knowledge score, dietary patterns and physical activity. Results: The prevalence of overweight and obesity was similar among women from high SES households compared with their low SES peers (48.4 vs. 44.8%). More than half (53%) of the women had poor dietary knowledge. Women from low SES households spent more time in moderate to vigorous intensity exercise (MVPA) compared with their high SES counterparts. Two distinct dietary patterns (Western and mixed) were identified. SEM results show that a unit increase in adherence to the ‘Mixed’ dietary pattern compared with ‘Western’ was associated with a 0.81 lower BMI kg/m2 (95% CI −1.54; −0.08), while ≥ 150 minutes’ MVPA per week was associated with a 1.94 lower BMI kg/m2 (95% CI −3.48; −0.41). Conclusion: The associations of SES, diet and physical activity on BMI must be taken into account when developing and designing interventions that target improvement in young women’s health
Maternal perceptions of infant's body weight and childhood obesity in South Africa: A qualitative study in Soweto
No full textFrom a socio-anthropological study focusing on maternal body weight perceptions and dietary practices towards infants living in Soweto (South Africa), we studied how lay sociocultural traits may lead to early childhood obesity. Most mothers tended to socially value and normalize fatness. This propensity led mothers, particularly older women at home, to adopt high-calorie feeding practices towards infants, although some mothers tended to question these lay norms. Further works must consider how lay (emic) sociocultural norms in African townships can contradict biomedical (etic) messages, conveying for the community thinness as the acceptable standard, and may expose infants to early obesity
The Healthy Aging Adult South Africa report card: a systematic review of the evidence between 2013 and 2020 for middle-aged South African men and women
No full textDue to the increasing non-communicable disease burden in Africa, several strategies that target the major lifestyle and physiological risk factors have been implemented to combat such diseases. The Healthy Aging Adult South Africa report card systematically reviews national and regional prevalence data of middle-aged South African adults (45–65 years) published between 2013 and 2020 on diet, physical activity, tobacco use and alcohol consumption, obesity, hypertension, dyslipidaemia and diabetes mellitus. Each indicator was assigned two grades, (1) based on the availability of prevalence data, and (2) based on whether policies have been proposed and implemented for the respective indicators. Alcohol consumption, obesity, hypertension and diabetes received an A grade for the availability of prevalence data. Tobacco use and diet received an A grade for policy and implementation. Gaps have been identified that need to be filled by future research focusing on continued surveillance of all indicators in order to inform and implement effective policies
Food insecurity, diet quality and body composition: data from the Healthy Life Trajectories Initiative (HeLTI) pilot survey in urban Soweto, South Africa
Full text linkObjective: To determine whether food security, diet diversity and diet quality are associated with anthropometric measurements and body composition among women of reproductive age. The association between food security and anaemia prevalence was also tested. Design: Secondary analysis of cross-sectional data from the Healthy Life Trajectories Initiative (HeLTI) study. Food security and dietary data were collected by an interviewer-administered questionnaire. Hb levels were measured using a HemoCue, and anaemia was classified as an altitude-adjusted haemoglobin level < 12·5 g/dl. Body size and composition were assessed using anthropometry and dual-energy x-ray absorptiometry. Setting: The urban township of Soweto, Johannesburg, South Africa. Participants: Non-pregnant women aged 18-25 years (n 1534). Results: Almost half of the women were overweight or obese (44 %), and 9 % were underweight. Almost a third of women were anaemic (30 %). The prevalence rates of anaemia and food insecurity were similar across BMI categories. Food insecure women had the least diverse diets, and food security was negatively associated with diet quality (food security category v. diet quality score: B = -0·35, 95 % CI -0·70, -0·01, P = 0·049). Significant univariate associations were observed between food security and total lean mass. However, there were no associations between food security and body size or composition variables in multivariate models. Conclusions: Our data indicate that food security is an important determinant of diet quality in this urban-poor, highly transitioned setting. Interventions to improve maternal and child nutrition should recognise both food security and the food environment as critical elements within their developmental phases.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
