Child-directed marketing on packaged breakfast cereals in South Africa.

OBJECTIVE: Childhood obesity is on the rise in South Africa (SA), and child-directed marketing (CDM) is one of the contributing factors to children's unhealthy food choices. This study assessed CDM on packaged breakfast cereals available in SA supermarkets and their nutritional quality. DESIGN: Photographic images were examined in a descriptive quantitative study. A codebook of definitions of CDM was developed for this purpose. REDCap, an online research database, was used for data capturing, and SPSS was used for data analyses including cross-tabulations and one-way ANOVA. SETTING: The current study was set in the Western Cape province of SA. SUBJECTS: Photographic images of all packaged breakfast cereals sold in major retailers in the Western Cape province of SA in 2019 were studied. RESULTS: CDM strategies were classified as direct (to the child) or indirect (through the parent). A total of 222 breakfast cereals were studied, of which 96·9 % had a nutritional or health claim, 95·0 % had illustrations, 75·2 % had product and consumption appeals, 10·8 % had characters, 10·8 % consisted of different appeals, 8·6 % alluded to fantasy and 7·7 % had role models. In breakfast cereals with direct CDM, the protein and fibre content was significantly lower than in breakfast cereals without direct CDM. This study found a significantly higher total carbohydrate and total sugar content in breakfast cereals with direct CDM than those without direct CDM. CONCLUSION: CDM was highly prevalent in breakfast cereals sold in SA. Regulations to curb the marketing of packaged foods high in nutrients of concern is recommended.

Determining food industry compliance to mandatory sodium limits: successes and challenges from the South African experience.

OBJECTIVE: To provide an update on the compliance to the Na reduction regulation (R.214) and to highlight some challenges and successes experienced by South Africa in the implementation of a mandatory Na regulation. DESIGN: The study design was observational. Nutritional information of packaged food (specified in the R.214 regulation) was collected between February 2019 and September 2020, before and after the implementation date of the final Na targets in the regulation. Six supermarket chains that accounted for more than 50 % of the grocery retailer market share in South Africa were included. The Na content (per 100 g) of products was extracted from photographs. Products were classified according to the thirteen food categories included in R.214. The percentage of targeted food categories that met the pre and post-regulation targets as well as the percentage by which Na limits were exceeded was calculated. SETTING: Low-and-middle-income suburbs in Cape Town, South Africa. PARTICIPANTS: N/A. RESULTS: A total number of 3278 products were analysed. After the final implementation date, none of the categories targeted by the R.214 regulation fully complied. However, nine out of the thirteen food categories targeted by R.214 were above the 70 % compliance mark. CONCLUSIONS: The compliance to R.214 in South Africa is good, although not 100 % compliant. This research also highlights the complexities regarding the monitoring and evaluation of a national regulation. Findings from the current study could aid by providing valuable information to countries in the process of implementing a Na reduction strategy.

Perceived effect of warning label on parental food purchasing and drivers of food selection among South African parents-An exploratory study.

Household food purchasing decision is a complex process influenced by factors such as marketing, cost, children food preference and parental choices. Most food products targeted toward children are unhealthy and are aggressively marketed to increase desirability among parents and children making healthier food selection even harder. The warning label (WL) is identified as a simple front-of-package labeling format that assist consumers to easily identify unhealthy foods and reduce their purchasing. This was a qualitative study that aimed to investigate the perceived effect of the warning label (WL) on parental food purchasing and drivers of food selection among parents. The study was conducted in a mainly rural part of South Africa, in Limpopo Province. Data were collected from 44 adult participants, all parents with children aged below 16 years selected using the snowball sampling method. Seven focus groups diversified according to age, literacy, income and urbanicity were utilized for data collection. Using a focus group discussion guide, parents were shown images of six products (crisps, soda, juice, biscuits, cereals, and yogurt) superimposed with the WL and questions asked were based on those images. Thematic analysis revealed that although some parents felt undeterred by the WL, some felt they would alter their food purchasing in the presence of the WL. Other parents felt they would reduce the frequency or the amount purchased or completely stop purchasing labeled products for their children. Motives behind perceived behavior modification included children's health being perceived as a priority and labeled products being viewed as unhealthy. Factors such as pressure from children, taste, poor nutrition knowledge and affordability seemed to influence parental food selection. These findings have important policy implications by providing evidence to policymakers that the WL may alter parental food purchasing and also provide insight into drivers of food selection among South African parents.

Effect of different front-of-package food labels on identification of unhealthy products and intention to purchase the products- A randomised controlled trial in South Africa.

This study aimed to evaluate the effect of different labels on participants identifying products high in nutrients of concern; identifying unhealthy products, and intention to purchase unhealthy products. This blinded randomised controlled trial included a representative sample of South African households (n = 1951). Per household we selected a member primarily responsible for food purchases. Participants were randomised into the Warning Label (WL), Guideline Dietary Amounts (GDA) or Multiple Traffic Light (MTL) arms. Each participant answered questions in a no label condition (control) followed by same questions in the label condition (experiment). Complete data were collected and analysed for 1948 participants (WL = 33.7%, GDA = 32.1% and MTL = 34.2%). The probability of correctly identifying products high in nutrients of concern and identifying products as being unhealthy was higher with the WL compared to the GDA or MTL for most items. There was no difference in performance between the GDA and the MTL when considering all items together. A higher percentage of participants reported a lower intention to purchase an unhealthy product after exposure to the WL compared to MTL for 5 out of 6 products; 2 out of 6 products for the WL compared to GDA and 2 out of 6 products for GDA compared to MTL. Compared to the control condition, exposure to each of the labels resulted in better identification of nutrients of concern, unhealthy products and a lower intention to purchase when considering all specific outcome items together. The WL showed a higher potential to enable South African consumers to identify products high in nutrients of concern, identify unhealthy products and discourage purchasing of unhealthy products.

Did COVID-19-Related Alcohol Sales Restrictions Reduce Alcohol Consumption? Findings from a National Online Survey in South Africa.

BACKGROUND: South Africa has a high prevalence of heavy episodic drinking (HED). Due to the high levels of alcohol misuse and violence, public hospital intensive care units were often overrun during the COVID-19 pandemic. This research investigated alcohol intake behaviour change during differing levels of lockdown restrictions, which included bans on alcohol sales. METHODS: A self-reported Facebook survey ran from July to November 2020. The questions included socio-demographics, income, alcohol intake, purchasing behaviour, and reasoning. Chi-square tests/Fisher's exact test for categorical data, Student's t-test for normal continuous data, and the Mann-Whitney U test for non-normal data were applied. Multiple logistic regression was run for HED versus moderate drinkers. RESULTS: A total of 798 participants took part in the survey, of which 68.4% were female. Nearly 50% of participants fell into the HED category and the majority bought alcohol illegally during restrictions. HED respondents who drank more alcohol than usual during restrictions reported that they felt stressed, needed to relax, and were bored. CONCLUSIONS: Policies intended to increase the pricing of alcohol may have the potential to reduce alcohol intake. Reducing stress and anxiety may be key to curtailing HED during emergency situations.

South African consumers' perceptions of front-of-package warning labels on unhealthy foods and drinks.

Front-of-package labeling (FOPL) is a policy tool that helps consumers to make informed food choices. South Africa has not yet implemented this labeling system. The aim of this study was therefore to explore adult South African consumers' perceptions of front-of-package warning labels on foods and non-alcoholic beverages (referred to as drinks in this paper) and their insights into features that could influence the effectiveness of the warning label. Using a qualitative approach, the study purposively selected consumers diversified by urbanization, gender, socioeconomic status, and literacy. We collected data from a total of 113 participants through 12 focus group discussions. Data were systematically coded and divided into five themes namely, positive attitudes toward warning labels, perceived benefits of warning labels, perceived behavior modification, perceived beneficiaries of warning labels, and effective attributes of warning labels. Almost all participants from all socio-economic backgrounds were positive about warning labels, reporting that warning labels concisely and understandably educated them about the nutritional composition of foods. Other perceived advantages were that warning labels warn of health implications, are easily understandable and could benefit child health. Some participants anticipated that warning labels would reduce their purchases of unhealthy foods, while others thought the labels would have no effect on their purchasing habits. Participants found the warning labels attention grabbing and stated that they preferred a black triangle placed on a white background (referred to as a holding strap henceforth), the words "high in" and "warning" in bold and uppercase text, an exclamation mark, and an icon depicting the excessive nutrient. In South Africa warning labels may improve consumer understanding of nutrition information and assist consumers in determining the nutritional quality of packaged foods and drinks.

Fortified Foods Are Major Contributors to Apparent Intakes of Vitamin A and Iodine, but Not Iron, in Diets of Women of Reproductive Age in 4 African Countries.

BACKGROUND: Food fortification is implemented to increase intakes of specific nutrients in the diet, but contributions of fortified foods to nutrient intakes are rarely quantified. OBJECTIVES: We quantified iron, vitamin A, and iodine intakes from fortified staple foods and condiments among women of reproductive age (WRA). METHODS: In subnational (Nigeria, South Africa) and national (Tanzania, Uganda) cross-sectional, clustered household surveys, we assessed fortifiable food consumption. We estimated daily nutrient intakes from fortified foods among WRA by multiplying the daily apparent fortifiable food consumption (by adult male equivalent method) by a fortification content for the food. Two fortification contents were used: measured, based on the median amount quantified from individual food samples collected from households; and potential, based on the targeted amount in national fortification standards. Results for both approaches are reported as percentages of the estimated average requirement (EAR) and recommended nutrient intake (RNI). RESULTS: Fortified foods made modest contributions to measured iron intakes (0%-13% RNI); potential intakes if standards are met were generally higher (0%-65% RNI). Fortified foods contributed substantially to measured vitamin A and iodine intakes (20%-125% and 88%-253% EAR, respectively); potential intakes were higher (53%-655% and 115%-377% EAR, respectively) and would exceed the tolerable upper intake level among 18%-56% of WRA for vitamin A in Nigeria and 1%-8% of WRA for iodine in Nigeria, Tanzania, and Uganda. CONCLUSIONS: Fortified foods are major contributors to apparent intakes of vitamin A and iodine, but not iron, among WRA. Contributions to vitamin A and iodine are observed despite fortification standards not consistently being met and, if constraints to meeting standards are addressed, there is risk of excessive intakes in some countries. For all programs assessed, nutrient intakes from all dietary sources and fortification standards should be reviewed to inform adjustments where needed to avoid risk of low or excessive intakes.

The effect of legislation on the treatment practices and role of naturopaths in South Africa.

BACKGROUND: In South Africa naturopaths have been practising for over half a century. Over this period, changes in legislation have resulted in different levels of training and registration processes - which has impacted on the profession in various ways. This paper explores the effect of legislation on the treatment practices and role of naturopaths in South Africa. METHODS: This was a qualitative study which used an exploratory approach. Participants were sampled from the list of naturopaths registered with the Allied Health Professions Council of South Africa (AHPCSA). A set of 15 open-ended survey questions were emailed to 59 naturopaths. Twenty one naturopaths participated: 13 responded via email and eight were interviewed. Responses were coded and thematically analysed. RESULTS: It was found that despite differences in training and years of practice experience, four core treatment practices of diet therapy, lifestyle medicine, supplementation and physical therapies were common to all participants with the older, more experienced naturopaths using a wider range of treatment practices. There is a shared common vision of wanting the profession to have greater participation in the public healthcare system. This research has found that legislation influences the treatment practices and role played by naturopaths in South Africa. The findings of this paper acknowledges the limiting impact of state legislation on naturopathic and other complementary medicine professions. CONCLUSION: Naturopathy has to operate within the legislative framework and this appears to be one of the key factors which has contributed to the lack of growth of naturopathy in South Africa. Findings thus highlight the need for new legislation to reflect the changes in society to ensure that the emergent healthcare needs of the population are met.

Urban Disadvantage, Obesity, and Underweight in 31 Lower-Income Countries.

Although some studies have shown that obesity and other non-communicable diseases are more common in more disadvantaged areas, no publications to date have examined the interaction of obesity with urban and rural disadvantage in lower-income countries. This study analyzed the rates of obesity and underweight in disadvantaged urban women and disadvantaged rural women in 31 lower-income countries, and calculated the age-adjusted odds ratios of urban vs. rural obesity and underweight. The odds of obesity were significantly (p<0.05) higher for urban populations in 16 of the 31 countries and in all aggregated regions; the evidence that underweight is also associated more with urban populations was mixed. Because obesity is a rapidly-growing threat to the public health and financial strength of lower-income countries, and urban disadvantage is associated with more obesity than rural disadvantage, policymakers should work to understand, predict, and prevent obesity in urban populations specifically.

An 11-country study to benchmark the implementation of recommended nutrition policies by national governments using the Healthy Food Environment Policy Index, 2015-2018.

The Healthy Food Environment Policy Index (Food-EPI) aims to assess the extent of implementation of recommended food environment policies by governments compared with international best practices and prioritize actions to fill implementation gaps. The Food-EPI was applied in 11 countries across six regions (2015-2018). National public health nutrition panels (n = 11-101 experts) rated the extent of implementation of 47 policy and infrastructure support good practice indicators by their government(s) against best practices, using an evidence document verified by government officials. Experts identified and prioritized actions to address implementation gaps. The proportion of indicators at "very low if any," "low," "medium," and "high" implementation, overall Food-EPI scores, and priority action areas were compared across countries. Inter-rater reliability was good (GwetAC2 = 0.6-0.8). Chile had the highest proportion of policies (13%) rated at "high" implementation, while Guatemala had the highest proportion of policies (83%) rated at "very low if any" implementation. The overall Food-EPI score was "medium" for Australia, England, Chile, and Singapore, while "very low if any" for Guatemala. Policy areas most frequently prioritized included taxes on unhealthy foods, restricting unhealthy food promotion and front-of-pack labelling. The Food-EPI was found to be a robust tool and process to benchmark governments' progress to create healthy food environments.

Dietary patterns and colorectal cancer risk in Zimbabwe: A population based case-control study.

BACKGROUND: The rising incidence of colorectal cancer in sub-Saharan Africa may be partly caused by changing dietary patterns. We sought to establish the association between dietary patterns and colorectal cancer in Zimbabwe. METHODS: One hundred colorectal cancer cases and 200 community-based controls were recruited. Data were collected using a food frequency questionnaire, and dietary patterns derived by principal component analysis. Generalised linear and logistic regression models were used to assess the associations between dietary patterns, participant characteristics and colorectal cancer. RESULTS: Three main dietary patterns were identified: traditional African, urbanised and processed food. The traditional African diet appeared protective against colorectal cancer (Odds Ratio (OR) 0.35; 95% Confidence Interval (CI), 0.21 - 0.58), which had no association with the urban (OR 0.68; 95% CI, 0.43-1.08), or processed food (OR 0.91; 0.58-1.41) patterns. The traditional African diet was associated with rural domicile, (OR 1.26; 95% CI, 1.00-1.59), and a low income (OR1.48; 95% CI, 1.06-2.08). The urbanised diet was associated with urban domicile (OR 1.70; 95% CI, 1.38-2.10), secondary (OR 1.30; 95% CI, 1.07-1.59) or tertiary education (OR 1.48; 95% CI, 1.11-1.97), and monthly incomes of $201-500 (OR 1.30; 95% CI, 1.05-1.62), and the processed food pattern with tertiary education (OR 1.42; 95% CI, 1.05-1.92), and income >$1000/month (OR 1.48; 95% CI, 1.02-2.15). CONCLUSION: A shift away from protective, traditional African dietary patterns may partly explain the rising incidence of colorectal cancer in sub-Saharan Africa.

'To be a woman is to make a plan': a qualitative study exploring mothers' experiences of the Child Support Grant in supporting children's diets and nutrition in South Africa.

Food security and good nutrition are key determinants of child well-being. There is strong evidence that cash transfers such as South Africa's Child Support Grant (CSG) have the potential to help address some of the underlying drivers of food insecurity and malnutrition by providing income to caregivers in poor households, but it is unclear how precisely they work to affect child well-being and nutrition. We present results from a qualitative study conducted to explore the role of the CSG in food security and child well-being in poor households in an urban and a rural setting in South Africa. SETTING: Mt Frere, Eastern Cape (rural area); Langa, Western Cape (urban township). PARTICIPANTS: CSG recipient caregivers and community members in the two sites . We conducted a total of 40 in-depth interviews with mothers or primary caregivers in receipt of the CSG for children under the age of 5 years. In addition, five focus group discussions with approximately eight members per group were conducted. Data were analysed using manifest and latent thematic content analysis methods. RESULTS: The CSG is too small on its own to improve child nutrition and well-being. Providing for children's diets and nutrition competes with other priorities that are equally important for child well-being and nutrition. CONCLUSIONS: In addition to raising the value of the CSG so that it is linked to the cost of a nutritious basket of food, more emphasis should be placed on parallel structural solutions that are vital for good child nutrition outcomes and well-being, such as access to free quality early child development services that provide adequate nutritious meals, access to adequate basic services and the promotion of appropriate feeding, hygiene and care practices.

An overview of the history and development of naturopathy in South Africa.

BACKGROUND: A huge growth in complementary and alternative medicine (CAM) took place in South Africa in the 1960s which paralleled what was happening in other parts of the western world. Naturopathy has been practised in South Africa for over 60 years, and the history of naturopathy is entwined with the broader history of CAM. No laws existed at that stage to regulate the curriculum, education and training of CAM practitioners. With the passage of time, various statutes were introduced which eventually led to changes in legislation and the establishment of a recognised training programme. Naturopathy became a legally regulated profession, the full history of which has never been documented. OBJECTIVE: This article explores the history of naturopathy in South Africa. METHOD: A two-phase qualitative research design was used, consisting of a document search and semi-structured interviews with key informants who were identified through a process of snowballing. Information collected from the naturopaths who participated in the interviews was triangulated with documentation uncovered in the archives of the Allied Health Professions Council of South Africa (AHPCSA) and other literature available. RESULTS: The result is a history of events which took place and reveals the effect of various legislations on the profession. CONCLUSION: Changes in the political system paved the way for changes in legislation which allowed for the registration and training of naturopathic practitioners. However, the lack of a functioning association and the small number of naturopathic graduates have hampered the growth of the profession, preventing it from becoming a significant contributor to the health care system.

Vitamin D Deficiency Increases the Risk for Moderate to Severe Disease Activity in Crohn's Disease Patients in South Africa, Measured by the Harvey Bradshaw Index.

OBJECTIVE: Vitamin D has immunoregulatory properties and appears to influence disease outcomes in patients with Crohn's disease (CD). The primary aim of this study was to evaluate the association between vitamin D status and CD activity in South Africa. METHODS: In a cross-sectional study performed between September 2011 and January 2013, serum 25-hydroxyvitamin D (25(OH)D) was measured in 186 consecutive patients with CD seen at 2 inflammatory bowel disease (IBD) centers and 199 healthy controls in the Western Cape, South Africa. Lifestyle and clinical variables were identified using an investigator-administered questionnaire, as well as clinical examination and patient case notes. Vitamin D status was evaluated in 2 ways: ≤ 20 ng/mL vs ≥ 21 ng/mL and ≤ 29 ng/mL vs ≥ 30 ng/mL. Disease activity was measured by the Harvey Bradshaw Index (HBI). Various 25(OH)D threshold concentrations for predicting a higher HBI score were also investigated. RESULTS: On multiple log-binomial regression analysis, higher HBI scores and not having taken vitamin D supplementation in the 6 months prior to enrollment were identified as risk factors for vitamin D deficiency in patients with CD, defined either as ≤ 20 ng/mL or as ≤ 29 ng/mL (p < 0.03). Compared to patients with HBI < 5, those with HBI ≥ 8 were 2.5 times more likely to have 25(OH)D concentrations ≤ 21 ng/mL (prevalence risk [PR] = 2.5; 95% confidence interval [CI], 1.21-6.30). The risk was similar, though not as high, when defined as ≤ 29 ng/mL (PR = 2.0; 95% CI, 1.13-3.51). When vitamin D deficiency was defined as <20, <30, <40, and <50 ng/mL, the sensitivity and specificity obtained were 44.9% and 78.8%; 75.5% and 62.4%; 86.7% and 44.7%; and 92.9% and 23.5%, respectively (area under the curve = 0.71; p < 0.0001). CONCLUSION: Low serum 25(OH)D was associated with increased CD activity in a South African cohort.

The association between childhood environmental exposures and the subsequent development of Crohn's disease in the Western Cape, South Africa.

BACKGROUND: Environmental factors during childhood are thought to play a role in the aetiolgy of Crohn's Disease (CD). However the association between age at time of exposure and the subsequent development of CD in South Africa is unknown. METHODS: A case control study of all consecutive CD patients seen at 2 large inflammatory bowel disease (IBD) referral centers in the Western Cape, South Africa between September 2011 and January 2013 was performed. Numerous environmental exposures during 3 age intervals; 0-5, 6-10 and 11-18 years were extracted using an investigator administered questionnaire. An agreement analysis was performed to determine the reliability of questionnaire data for all the relevant variables. RESULTS: This study included 194 CD patients and 213 controls. On multiple logistic regression analysis, a number of childhood environmental exposures during the 3 age interval were significantly associated with the risk of developing CD. During the age interval 6-10 years, never having had consumed unpasteurized milk (OR = 5.84; 95% CI, 2.73-13.53) and never having a donkey, horse, sheep or cow on the property (OR = 2.48; 95% CI, 1.09-5.98) significantly increased the risk of developing future CD. During the age interval 11-18 years, an independent risk-association was identified for; never having consumed unpasteurized milk (OR = 2.60; 95% CI, 1.17-6.10) and second-hand cigarette smoke exposure (OR = 1.93; 95% CI, 1.13-3.35). CONCLUSION: This study demonstrates that both limited microbial exposures and exposure to second-hand cigarette smoke during childhood is associated with future development of CD.

The association between race and Crohn's disease phenotype in the Western Cape population of South Africa, defined by the Montreal Classification System.

BACKGROUND: Inter-racial differences in disease characteristics and in the management of Crohn's disease (CD) have been described in African American and Asian subjects, however for the racial groups in South Africa, no such recent literature exists. METHODS: A cross sectional study of all consecutive CD patients seen at 2 large inflammatory bowel disease (IBD) referral centers in the Western Cape, South Africa between September 2011 and January 2013 was performed. Numerous demographic and clinical variables at diagnosis and date of study enrolment were identified using an investigator administered questionnaire as well as clinical examination and patient case notes. Using predefined definitions, disease behavior was stratified as 'complicated' or 'uncomplicated'. RESULTS: One hundred and ninety four CD subjects were identified; 35 (18%) were white, 152 (78%) were Cape Coloured and 7(4%) were black. On multiple logistic regression analysis Cape Coloureds were significantly more likely to develop 'complicated' CD (60% vs. 9%, p = 0.023) during the disease course when compared to white subjects. In addition, significantly more white subjects had successfully discontinued cigarette smoking at study enrolment (31% vs. 7% reduction, p = 0.02). No additional inter-racial differences were found. A low proportion of IBD family history was observed among the non-white subjects. CONCLUSIONS: Cape Coloured patients were significantly more likely to develop 'complicated' CD over time when compared to whites.
