METHODS: A total of 2322 Malaysian older adults aged 60 years and older were recruited using multistage random sampling in a population-based cross-sectional study. Out of 2322 older adults recruited, 2309 (48% men) completed assessments on cognitive function and body composition. Cognitive functions were assessed using the Malay version of the Mini-Mental State Examination, the Bahasa Malaysia version of Montreal Cognitive Assessment, Digit Span Test, Digit Symbol Test and Rey Auditory Verbal Learning Test. Body composition included body mass index, mid-upper arm circumference, waist circumference, calf circumference, waist-to-hip ratio, percentage body fat and skeletal muscle mass.
RESULTS: The association between body composition and cognitive functions was analyzed using multiple linear regression. After adjustment for age, education years, hypertension, hypercholesterolemia, diabetes mellitus, depression, smoking status and alcohol consumption, we found that calf circumference appeared as a significant predictor for all cognitive tests among both men and women (P
MATERIALS AND METHODS: 52 healthy volunteers were scanned in a 16-slice MDCT, and the volume of 104 sets of carpal bones was measured using a Syngo workstation (Both CT and workstation-Siemens Healthcare, Erlangen, Germany).
RESULTS: Male carpal bones were of higher volume compared to the female carpal bones (p<0.001). Area under the curve (AUC) assessment of responder-operator characteristics curves showed that the trapezium bone was best able to predict sex with an AUC of 0.986. At a trapezium bone volume of ⩾1.94cm(3), there was a 93.5% probability that the subject was male. Binary logistic regression analysis found that the highest accuracy was derived using the pisiform, trapezium and capitate bones. There was a strong relationship between sex prediction and grouping of the carpal bone volumes (Nagelkerke R(2)=0.923) with an overall prediction accuracy of 97%.
CONCLUSION: All 8 carpal bones exhibit sexual dimorphism to varying degrees. A binary regression analysis combining the 5 carpal bones with the highest predictive values for sex produces an accurate predictive model.
METHODS: This was a cross-sectional observational study. From 2013 to 2014, we recruited inhabitants aged 50 years or older in Guangzhou, China. Among 1,117 participants in the study, data from 1,015 phakic right eyes were used for analyses. Ocular parameters including axial length (AL), anterior chamber depth (ACD), and corneal curvature (K) were measured using an IOL Master.
RESULTS: The mean AL, ACD, and K were 23.48 mm [95 % confidence interval (CI), 23.40-23.55], 3.03 mm (CI, 3.01-3.05), and 44.20 mm (CI, 44.11-44.29), respectively. A mean reduction in ACD with age was observed (P = 0.002) in male subjects but not in female subjects (P = 0.558). Male subjects had significantly longer ALs (23.68 mm versus 23.23 mm, P sex were the most consistent predictors of ocular biometry in the older population from South China.
METHOD: Six hundred children aged 9-11 and 424 of their parents completely answered the child or parent versions of the SCAS.
RESULTS: Results indicated that the internal reliability of subscales were moderate to adequate. Significant correlations between child and parent reports supported the measure's concurrent validity. Additionally, anxiety levels in this Malaysian sample were lower than among South-African children and higher than among their Western peers. There were both similarities and differences between symptom items reported as often or always experienced by Malaysian students and by children from other cultures. Confirmatory factor analysis provided evidence of the existence of five inter-correlated factors for anxiety disorders based on SCAS-C.
CONCLUSION: Although some of the instrument's psychometric properties deviated from those observed in some other countries, it nevertheless appears to be useful for assessing childhood anxiety symptoms in this country.
METHODS: Healthy participants aged ≥ 60 years with no neurological conditions were recruited from rural and urban locations in Malaysia. HGS and KPS were measured using hand grip and key pinch dynamometers. Basic demographic data, anthropometric measures, modified Barthel Index scores and results of the Functional Reach Test (FRT), Timed Up and Go (TUG) test and Jebsen-Taylor Hand Function Test (JTHFT) were recorded.
RESULTS: 362 subjects aged 60-93 years were recruited. The men were significantly stronger than the women in both HGS and KPS (p < 0.001). The hand strength of the study cohort was lower than that of elderly Western populations. Significant correlations were observed between hand strength, and residential area (p < 0.001), FRT (r = 0.236, p = 0.028), TUG (r = -0.227, p = 0.009) and JTHFT (r = -0.927, p < 0.001).
CONCLUSION: This study established reference ranges for the HGS and KPS of rural and urban elderly Malaysian subpopulations. These will aid the use of hand strength as a screening tool for frailty among elderly persons in Malaysia. Future studies are required to determine the modifiable factors for poor hand strength.
METHODS: Using the National Diabetes Registry (2011-2020), we analyzed data for 221,769 adult Malaysians with T2D.We used quantile regressions to estimate the association of sex, age, and their interaction on HbA1clevels at the 5th, 50th, and 95thpercentile and logistic regression to estimate the odds of good control (HbA1c sexes. However, females had increasingly better control than men with increasing age (PHeterogeneity sexes, targeting especially the younger age groups, to improve glycemic control and reduce diabetes burden.
METHOD: This study conducted a snowball sampling and invited undergraduates to complete a survey via online. A sample of 445 Chinese undergraduate students (229 males, age range of 18-25 years) completed questionnaires concerning their mothers' monthly income and educational levels, emotional stability, and maternal parenting styles. Independent samples t-test, correlation analyses and regression analyses were performed.
RESULTS: The findings suggested the levels of emotional stability in female students were significantly lower than those of male students. Mothers' SES was related to late adolescents' emotional stability significantly. Moreover, maternal parenting styles (emotional warmth, punishment, overprotection, and rejection) significantly mediated the relationship between mothers' SES and late adolescents' emotional stability. Additionally, the particular features of these relationships varied according to the sex of the late adolescents. For the male students, maternal parenting styles could not significantly serve as mediating roles. For the female adolescents, the effect of maternal SES on emotional stability was partially mediated by four separate pathways: (1) maternal emotional warmth, (2) maternal punishment, (3) maternal overprotection, and (4) maternal rejection. These findings provide crucial practical implications for identification, prevention, and intervention efforts in late adolescents' emotional stability across sex.
CONCLUSION: This study sheds light on the relationship between mothers' SES and late adolescents' emotional stability, and the indirect effects of maternal emotional warmth, punishment, overprotection, and rejection serving as mediating roles. Maternal parenting styles had a higher effect on the emotional stability in female adolescents than male adolescents. This also provides crucial practical implications for identifying, preventing, and intervening in late adolescent emotional stability, which may differ between female and male adolescents.
METHODS: TOY8 was designed and developed to screen for developmental problems in children aged 3-5 years in Malay and English by an interdisciplinary research team drawing upon both national and international guidelines, and then reviewed by an expert panel (n = 5). Two samples of parents and their children were recruited: 1767 dyads to complete the English TOY8 and another 1724 dyads to complete the Malay TOY8.
RESULTS: The confirmatory factor analysis results indicated that the model structure of the English TOY8 matched that of the Malay TOY8. The split-half reliability coefficient indicated adequate to high reliability, which is also consistent with the Malay TOY8. Our results showed that all configural and metric invariance models across groups had a good fit to the data, demonstrating that multiple-group confirmatory factor analysis was appropriate. Finally, scalar invariance was only achieved in certain domains across gender and not in language versions or income groups.
CONCLUSION: The English TOY8 demonstrates construct validity and reliable screening tool for identifying developmental milestones in children aged 3-5 years in Malaysia. In addition, configural and metric invariances across groups in all domains were established, indicating the cross-cultural equivalence of the items, and scalar invariance was established across genders in most 3- to 5-year-old domains. These findings provide preliminary evidence supporting reliability and validity that aligns with previous literature on child development, which indicates a general similarity in the gender and cross-cultural development domains in the first years of life, but not for older children, in terms of language and socioemotional skills.
METHODS: Participants comprised 13 singers from a local cultural and heritage academy and 56 normal speakers from a local university, all were evaluated to have normal voices. Each participant underwent LHSV procedures to capture images of vocal fold vibration, which were subsequently analyzed to generate the LHSV-based measures.
RESULTS: Male singers exhibited lower F0GAW, jitterGAW, shimmerGAW, and OQGAW than female singers. When compared to normal speakers, male singers demonstrated higher F0GAW, and lower jitterGAW and shimmerGAW. No difference in OQGAW was found between male singers and normal speakers. Female singers exhibited lower jitterGAW compared to normal speakers, but no differences were observed in shimmerGAW and OQGAW. The results of Nyquist plots indicated no gender-related associations between types of rim width and among singers. However, for rim pattern, male singers were associated with a higher percentage of clustered rim, suggesting more regular vocal fold vibration, compared to female singers and normal male speakers.
CONCLUSIONS: Singers, particularly male singers, demonstrate distinct and potentially superior vocal fold vibrations compared to normal speakers, likely attributed to their regular vocal training, resulting in refined vocal fold configurations even during speaking. Despite the limited sample of singers, the study offers valuable insights into the vocal fold vibratory behaviors in singers analyzed using LHSV.
