Introduction: Malaysians are exposed to a high salt diet, which is one of the contributors to the prevalence of hypertension among them. This study aimed to identify the salt content in selected food products of fast food restaurants and to determine the salt intake awareness among fast food consumers. Methods: Salt content data were collected through online survey from the official websites of selected restaurants (Kentucky Fried Chicken, McDonald’s, Subway® and Texas Chicken). The food products were classified into eight food categories (chickenbased, potato-based, rice-based, sandwich, salad, bread, dessert, and sauce). The cross-sectional study on salt intake awareness was conducted among 108 Malaysian adults from these restaurants. A knowledge, attitude and practice (KAP) questionnaire was disseminated online. The salt content and the consumers’ salt intake awareness were analysed using Statistical Products and Service Solution (SPSS) software version 25.0. Results: A total of 105 food products were surveyed in this study. Sauce products contained the highest salt content (1.9±0.8 g/100g), followed by bread (1.2±0.3 g/100g), potato-based (1.2±0.4 g/100g), chicken-based (1.2±0.3 g/100g), sandwich (1.1±0.6 g/100g), rice-based (0.7±0.3 g/100g), salad (0.4±0.2 g/100g), and dessert (0.3±0.4 g/100g). For the KAP study, a total of 108 consumers had participated and mostly (48.2%) had a fair level of salt intake awareness. Conclusion: Most food products of fast food restaurants contained high salt content and majority of fast food consumers had a fair level of salt intake awareness. More strategic interventions are needed to control the salt intake among adults in Malaysia.

Introduction: Malaysian adults consume excessive amounts of salt daily, which could lead to hypertension. Understanding knowledge, attitudes, and practices (KAP) surrounding salt intake is crucial for designing effective interventions to reduce excessive consumption and its associated health risks. Therefore, this study aimed to adapt an existing salt intake-related KAP questionnaire that was previously employed in a local population-based survey and to validate and test its reliability. Methods: This cross-sectional study comprised two phases: (1) adaptation, content validation (CV), and face validation (FV); (2) pilot testing and reliability testing. CV and FV involved a total of seven experts and ten Malaysian adults from the Klang Valley, respectively. Pilot testing involved 139 Malaysian adults to determine the questionnaire’s reliability. Content validity index (CVI) and Face validity index (FVI) values were calculated to analyse CV and FV. Reliability of each domain was analysed by obtaining Cronbach’s alpha (α) values. Results: A self-administered questionnaire comprising six items each for knowledge, attitude, and practice was developed. The questionnaire demonstrated acceptable item-level CVI (I-CVI) and item-level FVI (I-FVI) values of at least 0.83, indicating that the items were relevant, clear, non-ambiguous, and simple. Reliability test showed acceptable α values of at least 0.70 for each domain, suggesting that the questionnaire was reliable. Conclusion: This tool could be considered valid and reliable for assessing the level of KAP towards salt intake among adults in Malaysia.
