Pregnant Women Are Iodine Deficient While School-Aged Children Demonstrate Adequate Iodine Status in Sarawak, Malaysia.

BACKGROUND: A mandatory universal salt iodization (USI) has been implemented in Sarawak, Malaysia since 2008. OBJECTIVES: The aim of this study is to assess the current iodine status among school-aged children (SAC) and pregnant women (PW) after 10 years of USI implementation in Sarawak. METHODS: This cross-sectional survey among school-aged children and pregnant women was conducted between July and October 2018 in Sarawak. The multistage proportionate to population size sampling technique was used to select 30 schools and 30 maternal and child health care clinics. A total of 1200 children aged 8 to 10 years and 750 first-trimester pregnant women were randomly selected to participate in the study. Iodine excretion level in urine was determined according to the World Health Organization classification. RESULTS: A total of 988 children and 677 PW participated in the study with a response rate of 82.3% and 90.2%, respectively. The overall median urinary iodine concentration (UIC) level among the children was 126.0 µg/L (interquartile range [IQR], 71.0-200.9 µg/L) and classified as adequate iodine status. The median UIC among PW was 123.9 µg/L (IQR, 56.5-192.1µg/L) indicating inadequate iodine status. CONCLUSION: The present findings indicate that despite adequate iodine status in children, the majority of PW still showed inadequate iodine status. Thus, comprehensive monitoring of the iodine deficiency disorder problem among PW is warranted.

Association between functional limitations and depression among community-dwelling older adults in Malaysia.

AIM: This study aimed to assess the relationship between functional limitations and depression among community-dwelling older adults in Malaysia. METHODS: Data from a nation-wide community-based cross-sectional study were analyzed. This study was conducted using a two-stage stratified random sampling design. In total, 3772 older adults aged ≥60 years responded to the survey. Depression was identified using a validated Malay version of the Geriatric Depression Scale (M-GDS-14), with those scored ≥6 categorized as having depression. Functional limitations were assessed using both Barthel's Activities of Daily Living (ADL) and Lawton's Instrumental Activities of Daily Living (IADL). The relationship was determined by multivariate logistic regression, adjusted for other variables. RESULTS: The prevalence of depression was 11.5% (95% confidence interval [CI] 9.4, 13.4). Multiple logistic regression analysis found that older adults with limitations in ADL were 2.6 times more likely of having depression (adjusted odds ratio [aOR] 2.58, 95% CI 2.01, 3.32), while those with limitations in IADL the risk of having depression was almost doubled (aOR 1.68, 95% CI: 1.32, 2.14). Other significant factors were incontinence (aOR 3.33, 95% CI: 2.33, 4.74), chronic medical illness (aOR 1.44, 95% CI: 1.15, 1.81), current smoker (aOR 4.19, 95% CI: 1.69, 10.39), poor social support (aOR 4.30, 95% CI: 2.98, 6.20), do not have partner, ethnic minorities and low individual monthly income. CONCLUSIONS: Older adults with functional limitation in both basic ADL and complex IADL are independently at higher risk of having depression. Geriatr Gerontol Int 2020; 20: 21-25.

Prevalence and determinants of hearing disability among older persons in Malaysia: Finding of National Health Morbidity Survey (NHMS) 2018.

AIM: An aging population is a potential burden for unprepared developing countries. Malaysia is foreseen to be an aging country by 2035. Thus, this study aimed to determine the prevalence and factors associated with hearing disability among older persons in Malaysia. METHODS: Data from a nationwide survey implemented using a stratified cluster sampling design were analyzed. This study was carried out through face-to-face interviews and guided questionnaires. The questions were based on the Washington Group of Disability (WG) questionnaires, which produce multiple disability identifiers. Hearing disability is defined as at least one domain or question out of four questions coded as "A lot of difficulty" or "Cannot hear at all". RESULTS: The prevalence of hearing disability among older persons aged ≥60 years was 6.4% (95% CI 5.0-8.3), whereas 1.5% (95% CI 0.90, 2.50) older persons were reported to be using a hearing aid. The determinants of hearing disability are being male (aOR 2.67, 95% CI 1.94-3.66), being unemployed (retired, homemaker, unemployed; aOR 1.86, 95% CI 1.86-4.14) and had no formal education (aOR 18.25, 95% CI 4.18-79.55). CONCLUSIONS: Promoting healthy aging is important and crucial for Malaysia, in preparation toward an aging nation, as it could reduce the country's financial burden in the long term. Health-related agencies should promote health awareness and treatment centers in relation to hearing disability among older persons, as they should be educated and informed about healthcare choices availability, which is aligned with the Global Disability Action Plan 2014-2021.

Prevalence and factors associated with physical inactivity among older adults in Malaysia: A cross-sectional study.

AIM: Physical inactivity in older adults is linked to increased risk of chronic diseases, disability and various poor health outcomes. As the aging population rises, the prevalence of diseases associated with aging also increases. Regular physical activity in older adults is important to improve overall health and promote healthy aging. This study aimed to determine the prevalence and factors associated with physical inactivity among older adults in Malaysia. METHODS: This study was based on 3969 Malaysian older adults aged ≥60 years who completed the physical activity module in the National Health and Morbidity Survey 2018, a population-based cross-sectional survey. Physical activity was measured using the Global Physical Activity Questionnaire through a face-to-face interview. Participants were classified as physically active or inactive. Associations between physical inactivity, sociodemographic characteristics and a range of selected independent variables were examined using multivariable logistic regression. RESULTS: Overall, three out of 10 (29.8%) Malaysian older adults were physically inactive. Results of multivariable analysis showed that older age group (≥80 years), of Bumiputera Sarawak ethnicity, unemployed/retirees/homemakers, functional limitation, diabetes mellitus and dementia were significantly associated with a higher risk of physical inactivity. Women, with secondary education level and good social support were less likely to be physically inactive. CONCLUSIONS: The present study reported the status of physical inactivity among older adults in Malaysia. There is the need to design effective public health programs and interventions to promote active living and healthy aging among Malaysian older adults, particularly in those at-risk older population subgroups.

The Association of Internet Addiction and Perceived Parental Protective Factors Among Malaysian Adolescents.

Parental protective factors do play an important role in preventing Internet addiction. A self-administered questionnaire was used to measure health risk behaviors among Malaysian adolescents. The prevalence of Internet addiction was significantly higher among adolescents with perceived lack of parental supervision (30.1% [95% confidence interval (CI) = 28.7-31.4]) and lack of parental connectedness (30.1% [95% CI = 28.5-31.7]), compared with their counterparts. Adolescents who perceived a lack of parental supervision, respect for privacy, connectedness, and bonding were more likely to have Internet addiction: (adjusted odds ratio [aOR] = 1.39; 95% CI = 1.27-1.52), (aOR = 1.23; 95% CI = 1.16-1.31), (aOR = 1.09; 95% CI = 1.02-1.16), (aOR = 1.06; 95% CI = 1.00-1.12), respectively. Among girls, Internet addiction was associated with those who perceived lack in all 4 parental factors, while among boys, those who perceived lack of parental supervision and respect for privacy were more prone to Internet addiction.

Prevalence and determinants of disability among adults in Malaysia: results from the National Health and Morbidity Survey (NHMS) 2015.

BACKGROUND: Reliable national data on disability which is internationally comparable is needed in Malaysia. This study aims to examine the prevalence of disability among adults in Malaysia and its determinants, particularly the socioeconomic factors and comorbidities. METHODS: This study was based on the disability module, which is part of the National Health and Morbidity Survey 2015. This survey was implemented using a multi-stage stratified sampling design. A locally validated Washington Group questionnaire was used to collect data on disability. RESULTS: Based on the definition of having at least one domain scored "a lot of difficulty or unable to do at all" or at least "some difficulty" scored in two domains, the prevalence of disability among adults in Malaysia was 11.8% (95% CI: 11.15, 12.53). Logistic regression analysis performed showed that population at risk of having disability in Malaysia were those of older people, ethnic minority, low level of education, single, obese, physically inactive and having mental health problems. Among older people, disability was significantly higher among those with no formal education, having mental health problems and physically inactive. CONCLUSIONS: The prevalence of disability among adults in Malaysia is comparable to WHO estimates and most developing countries. Planning for healthcare services should consider at-risk population, particularly older people and those from disadvantaged background to ensure equity healthcare.
