Salt reduction policy for out of home sectors: a supplementary document for the salt reduction strategy to prevent and control non-communicable diseases (NCDS) in Malaysia 2021-2025

Cardiovascular diseases (CVDs) are the major cause of death among Malaysians. Reduction of salt intake in populations is one of the most cost-effective strategies in the prevention of CVDs. It is very feasible as it requires low cost for implementation and yet could produce a positive impact on health. Thus, salt reduction initiatives have been initiated since 2010, and two series of strategies have been launched. However, there are issues on its delivery and outreach to the target audience. Further, strategies targeting out of home sectors are yet to be emphasized. Our recent findings on the perceptions, barriers and enablers towards salt reduction among various stakeholders including policy-makers, food industries, food operators, consumers and schools showed that eating outside of the home contributed to high salt intake. Foods sold outside the home generally contain a high amount of salt. Thus, this supplementary document is being proposed to strengthen the Salt Reduction Strategy to Prevent and Control Non-communicable Diseases (NCDs) for Malaysia 2021-2025 by focussing on the strategy for the out-of-home sectors. In this supplementary document, the Monitoring, Awareness and Product (M-A-P) strategies being used by the Ministry of Health (MOH) are adopted with a defined outline of the plan of action and indicators to ensure that targets could be achieved. The strategies will involve inter-sectoral and multi-disciplinary approaches, including monitoring of salt intake and educating consumers, strengthening the current enforcement of legislation on salt/sodium labelling and promoting research on reformulation. Other strategies included in this supplementary document included reformulation through proposing maximum salt targets for 14 food categories. It is hoped that this supplementary document could strengthen the current the Salt Reduction Strategy to Prevent and Control NCDs for Malaysia 2021-2025 particularly, for the out-of-home sector, to achieve a reduction in mean salt intake of the population to 6.0 g per day by 2025.

Strengthening national salt reduction strategies using multiple methods process evaluations: case studies from Malaysia and Mongolia

OBJECTIVE

To understand the extent to which national salt reduction strategies in Malaysia and Mongolia were implemented and achieving their intended outcomes.

DESIGN

Multiple methods process evaluations conducted at the mid-point of strategy implementation, guided by theoretical frameworks.

SETTING

Malaysia (2018-2019) and Mongolia (2020-2021).

PARTICIPANTS

Desk-based reviews of related documents, interviews with key stakeholders (n 12 Malaysia, n 10 Mongolia), focus group discussions with health professionals in Malaysia (n 43) and health provider surveys in Mongolia (n 12).

RESULTS

Both countries generated high-quality local evidence about salt intake and levels in foods and culturally specific education resources. In Malaysia, education and reformulation activities were delivered with moderate dose (quantity) but reach among the population was low. Within 5 years, Mongolia implemented education among schools, health professionals and food producers on salt reduction with high reach, but with moderate dose (quantity) and reach among the general population. Both countries faced challenges in implementing legislative interventions (mandatory salt labelling and salt limits in packaged foods) and both could improve the scaling up of their reformulation and education activities.

CONCLUSIONS

In the first half of Malaysia's and Mongolia's strategies, both countries generated necessary evidence and education materials, mobilised health professionals to deliver salt reduction education and achieved small-scale reformulation in foods. Both subsequently should focus on implementing regulatory policies and achieving population-wide reach and impact. Process evaluations of existing salt reduction strategies can help strengthen intervention delivery, aiding achievement of WHO's 30 % reduction in salt intake by 2025 target.

Perceptions, barriers and enablers on salt reduction in the out-of-home sectors in Malaysia (MySaltOH) from the perspective of street food vendors, caterers and consumers

OBJECTIVE

To explore the perspectives, barriers and enablers on salt reduction in out-of-home sectors in Malaysia among street food vendors, caterers and consumers.

DESIGN

A qualitative study involving twenty-two focus group discussions and six in-depth interviews was conducted, recorded and transcribed verbatim. An inductive thematic analysis approach was employed to analyse the data.

SETTING

Two in-depth interviews and twenty-two focus group discussions were conducted face-to-face. Four in-depth interviews were conducted online.

PARTICIPANTS

Focus group discussions were conducted among twenty-three street food vendors, twenty-one caterers and seventy-six consumers of various eateries. In-depth interviews were conducted among two street food vendors and four caterers, individually.

RESULTS

Consumers and food operators perceived a high-salt intake within Malaysia's out-of-home food sectors. Food operators emphasised the necessity for a comprehensive salt reduction policy in the out-of-home sector involving all stakeholders. Consumers faced limited awareness and knowledge, counterproductive practices among food operators and challenges in accessing affordable low-Na food products, whereas food operators faced the lack of standardised guidelines and effective enforcement mechanisms and uncooperative consumer practices. Both groups expressed that food quality and price of salt were also the barriers, and they advocated for awareness promotion, enhanced regulation of manufactured food products and stricter enforcement targeting vendors. Consumers also suggested promoting and recognising health-conscious food premises, whereas food operators suggested on knowledge enhancement tailored to them, strategies for gaining consumers acceptance and maintaining food quality.

CONCLUSIONS

These findings provide valuable insights that serve as foundational evidence for developing and implementing salt reduction policies within Malaysia's out-of-home sectors.

Fatty Acid Composition of Selected Street Foods Commonly Available in Malaysia

Despite growing evidence of increased saturated and trans fat contents in street foods, little is known about their fatty acid (FA) compositions. This study aimed to analyse the saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), and trans fatty acids (TFAs) content of 70 selected and most commonly available street foods in Malaysia. The street foods were categorised into main meals, snacks, and desserts. TFAs were not detected in any of the street foods. Descriptively, all three categories mainly contained SFAs, followed by MUFAs, and PUFAs. However, the one-way ANOVA testing showed that the differences between each category were insignificant (p > 0.05), and each FA was not significantly different (p > 0.05) from one to another. Nearly half of the deep-fried street foods contained medium to high SFAs content (1.7 g/100 g–24.3 g/100 g), while the MUFAs were also high (32.0–44.4%). The Chi-square test of association showed that the type of preparation methods (low or high fat) used was significantly associated (p < 0.05) with the number of SFAs. These findings provide valuable information about fat composition in local street foods for the Malaysian Food Composition Database and highlight the urgency to improve nutritional composition.

Perceptions, barriers and enablers of salt reduction in Malaysian out-of-home sectors (MySaltOH): from the point of view of policy-makers and food industries

BACKGROUND

High salt intake is a major cause of hypertension and cardiovascular diseases. The out-of-home sectors have been identified as one of the contributors of high salt intake in the population. The National Salt Reduction Policy of Malaysia was initiated in 2015; however, out-of-home sectors are yet to be emphasized and perception by policy-makers and the food industries towards salt reduction are yet unknown. This study aimed to determine the perceptions, barriers and enablers towards salt reduction in the out-of-home sector in Malaysia, as well as among policy-makers and the food industries.

METHODS

This is a qualitative study via semi-structured in-depth interviews (IDI) and focus group discussions (FGD) involving several stakeholders consisting of policy-makers from five ministries, five nongovernment organizations (NGOs) and food science/food technology researchers from five regions (West, North, East, and South Peninsular and East Malaysia/Borneo), as well as the food industries. The IDI and FGD sessions were recorded, transcribed verbatim and analysed thematically using Nvivo software version 12.

RESULTS

All participants agreed that salt intake in Malaysia is high and leads to hypertension and cardiovascular diseases. Lack of awareness, poor eating culture and behaviour and frequent eating out were among the causes of high salt intake. Awareness campaigns and education, sodium content labelling and product reformulation were strategies that have been implemented by the government; whilst for the food industries, some of them have tried to reduce salt and labelled the sodium content on their food products. However, there were several barriers including perceived poor consumer acceptance, lack of knowledge and resources, and challenges in reformulation, as well as unavailability of guidelines and salt targets. Hence, several enablers have been suggested, which include prioritizing the salt reduction strategy, creating more awareness, collaboration and engagement, research and technology particularly for reformulation and shelf-life stability, incentives and salt tax.

CONCLUSIONS

Salt reduction efforts of the out-of-home sector in Malaysia could be achieved through several measures or enablers that can overcome the barriers currently faced by stakeholders, especially policy-makers, food industries and the consumers themselves. This study will benefit the policy-makers to improve the salt reduction policy of out-of-home sectors and highlight the concerns among the food industries on the policy.

Developing a policy to reduce the salt content of food consumed outside the home in Malaysia: protocol of a qualitative study

INTRODUCTION

Current salt intake in Malaysia is high. The existing national salt reduction policy has faced slow progress and does not yet include measures to address the out of home sector. Dishes consumed in the out of home sector are a known leading contributor to daily salt intake. This study aims to develop a salt reduction strategy, tailored to the out of home sector in Malaysia.

METHODS AND ANALYSIS

This study is a qualitative analysis of stakeholder views towards salt reduction. Participants will be recruited from five zones of Malaysia (Western, Northern, Eastern and Southern regions and East Malaysia), including policy-makers, non-governmental organisations, food industries, school canteen operators, street food vendors and consumers, to participate in focus group discussions or in-depth interviews. Interviews will be transcribed and analysed using thematic analysis. Barriers will be identified and used to develop a tailored salt reduction strategy.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Universiti Kebangsaan Malaysia Medical Research Ethics Committee (UKM PPI/1118/JEP-2020-524), the Malaysian National Medical Research Ethics Committee (NMRR-20-1387-55481 (IIR)) and Queen Mary University of London Research Ethics Committee (QMERC2020/37) . Results will be presented orally and in report form and made available to the relevant ministries for example, Ministry of Health, Ministry of Education and Ministry of Trade to encourage adoption of strategy as policy. The findings of this study will be disseminated through conference presentations, peer-reviewed publications and webinars.

Knowledge, attitude and practice towards salt intake and health among non-academic staff of Universiti Kebangsaan Malaysia: A pilot study

Background: Over the years, global salt intake has increased and has resulted in the escalation of cardiovascular diseases and hypertension. The lack of knowledge, as well as poor attitude and practice, are the main reasons that have led to high salt intake. Therefore, this study aims to evaluate the knowledge, attitude and practice (KAP) towards salt intake and health among non-academic staff of the Faculty of Health Sciences (FSK), Universiti Kebangsaan Malaysia (UKM). Methodology: This cross-sectional study was conducted among the non-academic staff of the Faculty of Health Sciences (FSK), Universiti Kebangsaan Malaysia (UKM). The respondents were recruited using stratified random sampling technique with an informed consent. A validated questionnaire to test the knowledge, attitude and practice (KAP) towards salt intake and health by the Ministry of Health Malaysia was converted into a Google form and the link was emailed to 118 participants. A total of 33 responses were obtained for evaluation. The significant values were set as P < 0.05. Results: It was observed that female participants had better attitudes towards salt intake and health compared to males (p = 0.044). Also, individuals with higher education levels had better attitudes towards salt intake and health, compared to those with lower education levels (p=0.009). However, knowledge and practice of salt intake and health bore no significant results when considering gender, education level and age. Discussion and Conclusion: Overall, this study has identified sociodemographic characteristics as contributing factors towards individuals’ attitude on salt intake and health. This may provide a crucial foundation in the development of cost-effective healthcare programs to widen knowledge, create awareness and promote a healthy lifestyle by reducing salt intake and further reduce the prevalence of non-communicable diseases.

Salt intake was higher among males and those with high BMI and waist circumference: introduction to the Malaysian Community Salt Survey (MyCoSS), a population-based salt intake survey in Malaysia

BACKGROUND

Recognising that excessive dietary salt intake is associated with high blood pressure and adverse cardiovascular health, the Ministry of Health Malaysia conducted the Malaysian Community Salt Survey (MyCoSS) among Malaysian adults. This paper introduced MyCoSS projects and presented findings on the salt intake of the Malaysian adult population.

METHODS

MyCoSS was a nationally representative survey, designed to provide valuable data on dietary salt intake, sources of salt in the diet, and knowledge, perception, and practice about salt among Malaysian adults. It was a cross-sectional household survey, covering Malaysian citizens of 18 years old and above. Multi-stage-stratified sampling was used to warrant national representativeness. Sample size was calculated on all objectives studied, and the biggest sample size was derived from the knowledge on the effect of high salt on health (1300 participants). Salt intake was estimated using a single 24-h urine collection and its sources from a food frequency questionnaire. Knowledge, attitude, and practice were determined from a pre-tested questionnaire. All questionnaires were fully administered by trained interviewers using mobile devices. Anthropometric indices (weight, height, and waist circumference) and blood pressure were measured using a standardised protocol. Ethical approvals were obtained from the Medical Research Ethics Committee, Ministry of Health Malaysia, and Queen Mary University of London prior to conducting the survey.

RESULTS

Findings showed that the average sodium intake of Malaysian adults (3167 mg/day) was higher than the WHO recommendation of 2000 mg/day. Daily intake was significantly higher among males and individuals with higher BMI and higher waist circumference.

CONCLUSION

Salt intake in the Malaysian population was higher than the WHO recommendation. MyCoSS's findings will be used for the development and implementation of national salt reduction policy. A successful implementation of a national salt reduction programme in Malaysia will benefit the whole population.

Knowledge, attitude and behaviour on salt intake and its association with hypertension in the Malaysian population: findings from MyCoSS (Malaysian Community Salt Survey)

BACKGROUND

High blood pressure or hypertension has become one of the main health problems, worldwide. A number of studies have proven that an increased intake of salt was related to an increased prevalence of cardiovascular diseases. Of late, its relationship with high salt intake has received a lot of attention. Studies in Malaysia have shown both rising hypertension over time as well as high salt consumption. Actions to reduce salt intake are essential to reduce hypertension and its disease burden. As such, we carried out a study to determine associations between knowledge, attitude and behaviour towards salt intake and hypertension among the Malaysian population.

METHODS

Data obtained from the Malaysian Community Salt Survey (MyCoSS) was used partially for this study. The survey used a cross-sectional two-stage sampling design to select a nationally representative sample of Malaysian adults aged 18 years and above living in non-institutional living quarters (LQ). Face-to-face interviews were done by trained research assistants (RA) to obtain information on sociodemography, medical report, as well as knowledge, attitude and behaviour of the respondents towards salt intake and blood pressure.

RESULTS

Majority of the respondents have been diagnosed with hypertension (61.4%) as well as knowledge of the effects of high salt intake on blood pressure (58.8%). More than half of the respondents (53.3%) said they controlled their salt intake on a regular basis. Those who knew that a high salt diet could contribute to a serious health problem (OR=0.23) as well as those who controlled their salt intake (OR=0.44) were significantly less likely to have hypertension.

CONCLUSION

Awareness of the effects of sodium on human health, as well as the behaviour of controlling salt intake, is essential towards lowering the prevalence of hypertension among Malaysians.

A Survey on Salt Content Labeling of the Processed Food Available in Malaysia

Salt content in processed foods is high, and it is usually used as preservatives, stabilizers, and color enhancers in the products. Increased consumption of processed foods in the modern world has contributed to a high salt intake and thus increased the prevalence of hypertension among Malaysian populations. Therefore, this study aimed to identify and compare salt content in processed food products available in supermarkets and determine the percentage of processed food products exceeding the reference value stated in International Product Criteria (2016). The percentage of processed food products without salt and sodium labeling was determined in this study, in which 76.5% of unlabeled processed food products were made in Malaysia, while 23.5% were imported products. The food group with the highest average salt content was gravy and sauce (3.97 g/100 g), followed by soup (2.95 g/100 g), cheese (2.14 g/100 g), meat (1.37 g/100 g), fish (1.25 g/100 g), chicken (1.20 g/100 g), vegetables (1.18 g/100 g), butter and margarine (1.13 g/100 g), breakfast cereal (0.94 g/100 g), savory snacks (0.90 g/100 g), flatbread (0.86 g/100 g), sweet snacks (0.30 g/100 g), and potato (0.29 g/100 g). In addition, 79.5% of butter and margarine products had an average salt content above the reference value stated in the International Product Criteria, followed by gravy and sauce (79.3%), vegetables (72%), soup (50%), fish (49.2%), breakfast cereal (41%), cheese (36.6%), potato (36%), savory and sweet snacks (29.1), meat (12.5%) and chicken products (2.3%). Most processed food products available in local supermarkets were high in salt content.

Sodium content in sauces-a major contributor of sodium intake in Malaysia: a cross-sectional survey

OBJECTIVE

To investigate the sodium content in sauces sold in Malaysian supermarkets.

METHODS

A cross-sectional market survey was conducted in 2017 of 233 sauces sold in Malaysian supermarkets. Information on the sodium content was collected from the product packaging and nutrient information panels of the sauces sold in the seven top supermarkets in the capital of Malaysia.

RESULTS

Of the 233 sauces surveyed, 116 did not include sodium content information on the nutrient information panel (49.8%). Soy sauce (particularly sweet soy sauce) and ketchup (particularly chilli sauce) were found to be the highest number of products surveyed in the analysis (N=54 and N=48, respectively). The highest sodium content information was displayed by fish/prawn sauce (budu/cencalok) (5192±3228 mg/100 g) which was followed by the light/thin soy sauce (5116±2084 mg/100 g), and followed by salty soy sauce (4780±988 mg/100 g). The sodium content information of the imported sauces was higher compared with local products produced in Malaysia. However, for sweet soy sauce, the sodium content information of the local products was higher compared with the imported products. Of the 116 sauces which displayed information regarding their sodium content, only 18.2% of the salty soy sauce and 25% of the light/thin soy sauce were found to be below the 2017 Malaysian sodium guidelines. Furthermore, only 21.7% of chilli ketchup and no tomato ketchup were below the 2017 UK salt guidelines.

CONCLUSIONS

Almost half of the sauces surveyed did not include sodium content information on the nutrient information panel. It is recommended that sodium content information is provided on all sauces sold in Malaysia. Also, manufacturers should be urged to reduce the sodium content level of their sauces to a minimum of 5%.

Renal cell carcinoma in children under 14 years old: long-term survival

OBJECTIVES

To assess the treatment and long-term survival of children under 14 years old operated upon for renal cell carcinoma (RCC).

PATIENTS AND METHODS

The records of five patients (aged 2, 4, 6, 9 and 13 years) who had been treated for RCC between 1982 and 1993 were reviewed. All had undergone nephrectomy with (two) or without (three) regional lymphadenectomy. After surgery four patients received chemotherapy (vincristine with actinomycin-D, three, vinblastine, one), and two with advanced-stage disease received other agents (interferon alpha, interleukin-2). They were followed for 5 to 15 years.

RESULTS

Three patients with stage I-II RCC were well at 13, 15 and 15 years after treatment. Of the two patients with regional lymph node involvement (stage III), one was well 5 years after surgery while the other developed hepatic, lung and bone metastases, and died 2 years after presentation.

CONCLUSION

The prognosis and long-term survival of children under 14 years old with RCC is very good for those with low-stage tumours. Nephrectomy with complete tumour extirpation is the main mode of treatment. For advanced-stage tumours, the role of adjuvant chemotherapy and/or biological agents must be defined more clearly.

Effects of submucosal Teflon paste injection in vesicoureteric reflux: results with 1- and 2-year follow-up data

One hundred refluxing ureters with grades II (n = 65), III (n = 27) and IV (n = 8) vesicoureteric reflux (VUR) were treated with endoscopic submucosal polytetrafluoroethylene (Teflon) paste injection. Reflux stopped in 77 ureters after a single injection and in 13 ureters following a second injection. Two ureters remained with minimal (grade I) residual reflux, whilst in another 5 improvement from grades III and IV to grade II reflux was noted. In 3 ureters reflux remained unchanged, because of lateral ectopia of the refluxing ureteric ostium, hindering the injection of Teflon into the correct position. Re-evaluation at 1 year postinjection, of 48 previously cured ureters showed recurrence of reflux in 1 (2%), but no further recurrences were noted in 19 ureters reevaluated after 2 years.

Paediatric urolithiasis in Greece

A group of 44 patients, aged from 10 months to 14 years, underwent surgery for urinary calculi over a 7-year period (1982-1989). Eleven patients had bilateral or multiple calculi (total number of stones = 55, 20 of which were staghorn). Metabolic disorders (n = 25) and Proteus urinary infection (n = 15) were the 2 factors most often associated with lithiasis. Of the 55 stones, 51 were removed by open surgery. Complete stone clearance was achieved in 29 of 36 kidneys. Follow-up periods in the remaining 7 renal units (with small residual fragments) ranged from 3.5 to 7.5 years (mean 6.2) and revealed stone recurrence in only 2 patients. Evaluation of childhood urolithiasis should include thorough metabolic investigation and sound surgical judgment; effective management requires prolonged post-operative follow-up.

Ostioplasty: a simple technique for ureterovesical reconstruction following intravesical ureterocelectomy

A simple operation for the management of simple, i.e. intravesical, ureteroceles, which we have named 'ostioplasty', is presented. After unroofing the ureterocele, the retracted, gaping ureteric ostium is advanced and fixed medially to the center of the bladder trigone with three 5-0 polyglycolic acid sutures. The exposed intravesical ureter is covered with a new mucosal layer formed from the mobilized lateral edges of the unroofed ureterocele, sutured together over the ureter with 5-0 polyglycolic acid. Ostioplasty has been used in 5 patients so far with excellent anatomic and functional results. It is a simple and valuable surgical option to standard ureterovesical reimplantation after excision of a simple ureterocele, provided that the ureterocele is of moderate size and the bladder trigone retains good muscular support.
