Background: Mobile health (mHealth) apps play an important role in delivering education, providing advice on treatment, and monitoring patients’ health. Good usability of mHealth apps is essential to achieve the objectives of mHealth apps efficiently. To date, there are questionnaires available to assess the general system usability but not explicitly tailored to precisely assess the usability of mHealth apps. Hence, the mHealth App Usability Questionnaire (MAUQ) was developed with 4 versions according to the type of app (interactive or standalone) and according to the target user (patient or provider). Standalone MAUQ for patients comprises 3 subscales, which are ease of use, interface and satisfaction, and usefulness. Objective: This study aimed to translate and validate the English version of MAUQ (standalone for patients) into a Malay version of MAUQ (M-MAUQ) for mHealth app research and usage in future in Malaysia. Methods: Forward and backward translation and harmonization of M-MAUQ were conducted by Malay native speakers who also spoke English as their second language. The process began with a forward translation by 2 independent translators followed by harmonization to produce an initial translated version of M-MAUQ. Next, the forward translation was continued by another 2 translators who had never seen the original MAUQ. Lastly, harmonization was conducted among the committee members to resolve any ambiguity and inconsistency in the words and sentences of the items derived with the prefinal adapted questionnaire. Subsequently, content and face validations were performed with 10 experts and 10 target users, respectively. Modified kappa statistic was used to determine the interrater agreement among the raters. The reliability of the M-MAUQ was assessed by 51 healthy young adult mobile phone users. Participants needed to install the MyFitnessPal app and use it for 2 days for familiarization before completing the designated task and answer the M-MAUQ. The MyFitnessPal app was selected because it is one among the most popular installed mHealth apps globally available for iPhone and Android users and represents a standalone mHealth app. Results: The content validity index for the relevancy and clarity of M-MAUQ were determined to be 0.983 and 0.944, respectively, which indicated good relevancy and clarity. The face validity index for understandability was 0.961, which indicated that users understood the M-MAUQ. The kappa statistic for every item in M-MAUQ indicated excellent agreement between the raters (κ ranging from 0.76 to 1.09). The Cronbach α for 18 items was .946, which also indicated good reliability in assessing the usability of the mHealth app. Conclusions: The M-MAUQ fulfilled the validation criteria as it revealed good reliability and validity similar to the original version. M-MAUQ can be used to assess the usability of mHealth apps in Malay in the future.

Breakfast frequency is associated with cardiovascular disease (CVD) risk in Western populations, possibly via the types of food eaten or the timing of food consumption, but associations in Malaysian adolescents are unknown. While the timing of breakfast is similar, the type of food consumed at breakfast in Malaysia differs from Western diets, which allows novel insight into the mechanisms underlying breakfast–CVD risk associations. We investigated foods eaten for breakfast and associations between breakfast frequency and CVD risk factors in the Malaysian Health and Adolescents Longitudinal Research Team study (MyHeARTs). Breakfast (frequency of any food/drink reported as breakfast in 7-day diet history interviews) and CVD risk factors (body mass index (BMI), waist circumference, fasting blood glucose, triacylglycerol, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and systolic and diastolic blood pressure) were cross-sectionally associated using linear regression adjusting for potential confounders (n = 795, age 13 years). Twelve percent of adolescents never ate breakfast and 50% ate breakfast daily, containing mean (SD) 400 (±127) kilocalories. Commonly consumed breakfast foods were cereal-based dishes (primarily rice), confectionery (primarily sugar), hot/powdered drinks (primarily Milo), and high-fat milk (primarily sweetened condensed milk). After adjustment, each extra day of breakfast consumption per week was associated with a lower BMI (−0.34 kg/m², 95% confidence interval (CI) −0.02, −0.66), and serum total (−0.07 mmol/L 95% CI −0.02, −0.13) and LDL (−0.07 mmol/L 95% CI −0.02, −0.12) cholesterol concentrations. Eating daily breakfast in Malaysia was associated with slightly lower BMI and total and LDL cholesterol concentrations among adolescents. Longitudinal studies and randomized trials could further establish causality.

Background: It is considered that the implementation of nutrition care process (NCP) leads to more efficient and effective care, as well as enhancing the roles of dietetics and nutrition professionals in the clinical setting. However, little is known about the NCP being implemented in the sports nutrition setting to deliver nutrition care, especially in meal planning. Therefore, this study aims to identify the process that sports nutritionists (SNs) practise in meal planning to plan meals for athletes and identify the application of NCP.Methods: In-depth interviews, using semi-structured interview questions, were conducted with SNs employed at the National Sports Institute of Malaysia. Five SNs who managed different types of sports were recruited. The interviews were audio-recorded and transcribed verbatim. Data were entered into ATLAS.ti 8 and analyzed using thematic analysis.Results: The following processes were identified: (i) collecting pertinent data; (ii) analyzing the collected data; (iii) determining nutrition prescriptions; (iv) formulating goals and determining actions; (v) implementing actions and recommendations; and (vi) monitoring.Conclusions: This study identified 6 general processes practiced by sports nutritionists in meal planning that comprised of the NCP’s interrelated steps, except nutrition diagnosis statement from the Nutrition Diagnosis step of the NCP. A comprehensive process and workflow can help sports dietitians or nutritionists to develop individualized meal plans that can improve athletes’ nutritional status, adherence, health and sports performance.

BACKGROUND Food insecurity, defined as the lack of physical and economic access to adequate, safe, and nutritious food, may compromise dietary adherence among patients with end-stage renal disease (ESRD) undergoing haemodialysis. Given their stringent dietary requirements, food insecurity may adversely affect nutritional management and health outcomes. However, research on food insecurity among haemodialysis patients in Malaysia remains limited. OBJECTIVE This study aimed to determine the prevalence and determinants of food insecurity and its association with nutritional status in this population. METHODS This cross-sectional study was conducted among 287 adults (≥ 18 years old) receiving maintenance haemodialysis for at least three months at four dialysis centres operated by the Pahang Islamic Religious Council and Malay Customs (Majlis Ugama Islam dan Adat Resam Melayu Pahang, MUIP). Food security status was measured using the Malay version of the Food Insecurity Experience Scale (M-FIES). Its determinants were assessed using validated, interviewer-administered questionnaires. Nutritional status was characterised by anthropometric measurements (post-dialysis), biochemical parameters obtained from the patients’ medical record, clinical indicators including the Malnutrition Inflammation Score (MIS) and protein energy wasting (PEW), and three-day dietary intake assessed via 24-hour dietary recalls. Data were analysed using linear and logistic regression. RESULTS About one-third of participants were food insecure, with 16.4% mildly, 9.4% moderately, and 5.6% severely food insecure. Younger age (aOR=9.816, 95% CI=3.189-30.211, p<0.001), lower educational attainment (aOR=7.968, 95% CI=1.619-39.213, p=0.011), inability to afford food (aOR=12.364, 95% CI=1.040-146.930, p=0.046), and inconsistent adherence to dietary recommendations (aOR=2.659, 95% CI=1.170-6.042, p=0.020) were independently associated with food insecurity. However, no significant association was observed between food security status and nutritional status indicators. CONCLUSIONS Food insecurity affects approximately one in every three haemodialysis patients attending the selected dialysis centres in Pahang and is driven by socioeconomic and behavioural factors. Although not directly associated with current nutritional status, its substantial prevalence underscores the need for routine screening and integrated nutrition–social support strategies within dialysis care to mitigate long-term risks and support sustainable dietary adherence.
