Knowledge, attitudes and perception on dietary salt reduction of two communities in Grahamstown, South Africa

Exploring Dietary Salt Knowledge, Attitude, and Practices among People of African Descent in the United Kingdom: A Qualitative Study

Background/Objectives: People of African Descent (PoAD) in the United Kingdom (UK) are at an increased risk of hypertension and cardiovascular disease (CVD), partly due to dietary habits such as high salt intake. This study sought to understand the dietary salt-related knowledge, attitudes, and practises (KAP) of PoAD in the UK, to inform the development of culturally tailored interventions to reduce dietary salt intake in this population. Methods: We collected data on KAP from 21 PoAD across various regions in the UK through online semi-structured interviews and analysed them using reflexive thematic analysis (TA). Results: The age of the participants ranged from 20 to 70 years (43 ± 11). Six overarching themes were identified: (i) the multifaceted roles of salt in culinary practises, (ii) the increased awareness of health risks associated with high salt intake, (iii) the existence of knowledge gaps regarding recommended daily salt intake, (iv) the cultural influences on salt consumption levels, (v) the lack of engagement with food labels, and (vi) a limited awareness of salt reduction initiatives. Conclusions: Our findings highlight the significance of salt in the culture and culinary practises of PoAD. Despite general awareness of the health risks of excessive salt consumption, there was a notable deficiency in knowledge about the recommended salt intake levels as well as minimal engagement with nutritional labelling. These findings underline a need for culturally sensitive health interventions that integrate culinary practises, beliefs, and preferences of PoAD, aiming to effectively reduce salt intake and mitigate associated health risks.

Identifying correlates of salt reduction practices among rural, middle-aged Muslim Indonesians with hypertension through structural equation modeling

Background: In 2016, the World Health Organization recommended salt reduction strategies. In most low- and middle-income countries, little is known about what causes people to reduce their salt intake. Aim: In rural West Java, Indonesia, we conducted a cross-sectional survey to describe self-reported salt reduction practices among middle-aged Muslims with hypertension (n = 447) and to identify correlates of salt reduction. Methods: We developed a questionnaire with Likert scales to measure self-reported frequency of efforts to reduce salt intake, and degree of agreement/disagreement with 51 statements about variables hypothesized to influence salt reduction practices. We compared groups using t-tests and one-way ANOVAs. Through one-factor confirmatory factor analysis and structural equation modeling, we identified correlates of salt reduction practices. Results: About 45% of participants reported regularly reducing their salt intake; only 12.8% reported never attempting. Men reported higher social barriers, while women reported higher family support and spiritual support. Overall, we found that participants' frequency of effort to reduce their salt intake was associated with a constellation of six correlates. Salt reduction practices were directly positively associated with prior health/illness experiences (β = 0.25), and by seeking health information (β = 0.24). Seeking health information was in turn positively associated with prior health/illness experiences (β = 0.34), receiving support from health professionals (β = 0.23) and Islamic spiritual practice (β = 0.24). Salt reduction practices were negatively associated with environmental barriers to healthful eating practices (β = -0.14). Conclusion: In this population, reinforcing positive correlates identified in this study and mitigating against negative correlates may foster salt reduction practices.

Monitoring and implementation of salt reduction initiatives in Africa: A systematic review

This systematic review aims to document salt consumption patterns and the implementation status and potential impact of salt reduction initiatives in Africa, from studies published between January 2009 and November 2019. Studies were sourced using MEDLINE, Embase, Cochrane Library electronic databases, and gray literature. Of the 887 records retrieved, 38 studies conducted in 18 African countries were included. Twelve studies measured population salt intake, 11 examined salt level in foods, 11 assessed consumer knowledge, attitudes, and behaviors, 1 study evaluated a behavior change intervention, and 3 studies modeled potential health gains and cost savings of salt reduction interventions. The population salt intake studies determined by 24‐hour urine collections showed that the mean (SD) salt intake in African adults ranged from 6.8 (2.2) g to 11.3 (5.4) g/d. Salt levels in foods were generally high, and consumer knowledge was fairly high but did not seem to translate into salt lowering behaviors. Modeling studies showed that interventions for reducing dietary sodium would generate large health gains and cost savings for the health system. Despite this evidence, adoption of population salt reduction strategies in Africa has been slow, and dietary consumption of sodium remains high. Only South Africa adopted legislation in 2016 to reduce population salt intake, but success of this intervention has not yet been fully evaluated. Thus, rigorous evaluation of the salt reduction legislation in South Africa and initiation of salt reduction programs in other African countries will be vital to achieving the targeted 30% reduction in salt intake by 2025.

Parents' Perceptions about Salt Consumption in Urban Areas of Peru: Formative Research for a Social Marketing Strategy

Background: Salt intakes in Latin America currently double the World Health Organization’s recommendation of 5 g/day. Various strategies to reduce the population’s salt consumption, such as raising awareness using social marketing, have been recommended. This study identified parents’ perceptions of salt consumption to inform a social marketing strategy focused on urban areas in Peru. Methods: Using a sequential exploratory methods design, parents of pre-school children, of high and low socioeconomic status, provided qualitative data in the form of interviews and focus groups. Following this, quantitative data was obtained via questionnaires, which were sent to all parents. The information was analyzed jointly. Results: 296 people (mean age 35.4, 82% women) participated, 64 in the qualitative and 232 in the quantitative phase of the study. Qualitative data from the first phase revealed that the majority of mothers were in charge of cooking, and female participants expressed that cooking was “their duty” as housewives. The qualitative phase also revealed that despite the majority of the participants considered their salt intake as adequate, half of them mentioned that they have tried to reduce salt consumption, and the change in the flavor of the food was stated as the most difficult challenge to continue with such practice. Quantitative data showed that 67% of participants would be willing to reduce their salt intake, and 79.7% recognized that high salt intake causes hypertension. In total, 84% of participants reaffirmed that mothers were in charge of cooking. There were no salient differences in terms of responses provided by participants from high versus low socioeconomic groups. Conclusions: The results point towards the identification of women as a potential target-audience of a social marketing strategy to promote reductions in salt intake in their families and, therefore, a gender-responsive social marketing intervention is recommended.

Community awareness of diet needs associated with hypertension and type 2 diabetes mellitus in Hatcliffe, Zimbabwe

BACKGROUND

Diet is an important modifiable risk factor for non-communicable diseases (NCDs) like hypertension (HTN) and type 2 diabetes mellitus (T2DM). A NCD is a disease that cannot be transmitted from person to person. Dietary risk factors account for 5.8% of all-cause mortality in Sub-Saharan Africa (SSA). There has been an increase in the consumption of 'westernized 'diets in SSA. The westernized diets consumed in low-income countries are usually high in salt content, fatty, processed and fast foods; and hence accelerate the development of HTN and T2DM. Previous studies carried out in Zimbabwe showed low levels of knowledge and awareness of HTN and T2DM; and the dietary needs for patients with those conditions. The aim of this study was to explore the dietary habits and awareness of HTN and T2DM of both males and females in a high-density area (HDA) of Zimbabwe.

METHODS

We conducted household-based cross-sectional study in a high density area of Hatcliffe, which has a population of close to 50,000 residents. Face to face interviews were conducted using hand-held mobile devices loaded with KoBo Toolbox. We selected two consenting adults, a male and female, from every fourth household in selected areas of Hatcliffe.

RESULTS

In this study all the 492 participants that were interviewed responded. Eighty eight point 6% (88.6%) of the participants in the study did not know if they were hypertensive or not. In addition, 91.7% of the participants had never voluntarily checked for hypertension. Similarly, 97.6% of the participants did not know if they had T2DM or not. Ninety eight percent (98%) of the participants had not voluntarily checked their blood glucose level.

CONCLUSIONS

The majority of the participants in the study were not aware if they had HTN or T2DM. The participants in the study perceived that the salt they consume is the right quantity. There is a high consumption of vegetable oil in most meals prepared.

Knowledge and behaviors regarding salt intake in Mozambique

BACKGROUND/OBJECTIVES

Health education and regulatory measures may contribute to lower population salt intake. Therefore, we aimed to describe knowledge and behaviors related to salt intake in Mozambique.

SUBJECTS/METHODS

A cross-sectional evaluation of a representative sample of the population aged 15-64 years (n = 3116) was conducted in 2014/2015, following the Stepwise Approach to Chronic Disease Risk Factor Surveillance, including a 12-question module for evaluation of dietary salt.

RESULTS

Three dimensions were identified in the questionnaire, named "self-reported salt intake", "knowledge of health effects of salt intake", and "behaviors for control of salt intake". A total of 7.4% of the participants perceived that they consumed too much/far too much salt and 25.9% reported adding salt/salty seasoning often/always to prepared foods. The proportion considering that it was not important to decrease the salt contents of their diet was 8%, and 16.9% were not aware that high salt intake could be deleterious for health. Prevalences of lack of behaviors for reducing salt intake ranged from 74.9% for not limiting consumption of processed foods, to 95% for not buying low salt alternatives. There were few differences according to socio-demographic variables, but awareness of hypertension was, in general, associated with better knowledge and less frequent behaviors likely to contribute to a high salt intake.

CONCLUSIONS

Most Mozambicans were aware that high salt intake can cause health problems, but the self-reported salt intake and behaviors for its control show an ample margin for improvement. This study provides evidence to guide population level salt-reducing policies.
