Brain size varies greatly at all taxonomic levels. Feeding ecology, life history and sexual selection have been proposed as key components in generating contemporary diversity in brain size across vertebrates. Analyses of brain size evolution have, however, been limited to lineages where males predominantly compete for mating and females choose mates. Here, we present the first original data set of brain sizes in pipefishes and seahorses (Syngnathidae) a group in which intense female mating competition occurs in many species. After controlling for the effect of shared ancestry and overall body size, brain size was positively correlated with relative snout length. Moreover, we found that females, on average, had 4.3% heavier brains than males and that polyandrous species demonstrated more pronounced (11.7%) female-biased brain size dimorphism. Our results suggest that adaptations for feeding on mobile prey items and sexual selection in females are important factors in brain size evolution of pipefishes and seahorses. Most importantly, our study supports the idea that sexual selection plays a major role in brain size evolution, regardless of on which sex sexual selection acts stronger.

Fulltext Associations between socio-demographic characteristics and pubertal status with disordered eating among primary school children in Selangor, Malaysia

Chong LS, Chin YS, Gan WY, Nasir MT

Asia Pac J Clin Nutr, 2017 Mar;26(2):326-333.
PMID: 28244713 DOI: 10.6133/apjcn.012016.10

BACKGROUND AND OBJECTIVES: To determine the associations between socio-demographic characteristics and pubertal status with disordered eating among primary school children.
METHODS AND STUDY DESIGN: Using a stratified multi-stage sampling, a total of 816 children (282 boys and 534 girls) aged 10 to 11 years from 12 selected primary schools in the state of Selangor, participated in this study. Data were collected on socio-demographic characteristics, pubertal status and disordered eating behaviors. The Pubertal Development Scale and the Children's Eating Attitudes Test (ChEAT) were used to assess pubertal status and disordered eating, respectively. Logistic regression analysis was conducted to determine the risk factors of disordered eating.
RESULTS: The prevalence of disordered eating was 30.8% (32.8% in boys and 29.7% in girls). However, the sex difference in the prevalence was not statistically significant. Age, ethnicity and pubertal status were significantly associated with disordered eating in univariate logistic regression analysis. Multivariate logistic regression analysis showed that among boys, being either in an advanced or post-pubertal stage (adjusted OR=8.64) and older age group (adjusted OR=2.03) were risk factors of disordered eating. However, among girls, being a Malay (adjusted OR=3.79) or Indian (adjusted OR=5.04) in an advanced or post-pubertal stage (adjusted OR=2.34) and older age group (adjusted OR=1.53) were risk factors of disordered eating.
CONCLUSION: This study found one in three children had disordered eating. Since ethnicity and pubertal status were identified as risk factors, ethnicity-specific intervention programs on the prevention of disordered eating among children should take into consideration their pubertal status.

Excessive internet use in young women: What are the implications?

Jaafar NRN, Bahar N, Ibrahim N, Wan Ismail WS, Baharudin A

Curr Opin Psychiatry, 2017 Jul;30(4):260-267.
PMID: 28426547 DOI: 10.1097/YCO.0000000000000336

PURPOSE OF REVIEW: There are considerable gender differences in youth engaging in excessive internet use (EIU). This review provides updates based on the recent literature focusing on the EIU in young women to describe its implications including what it constitutes of, its correlates, sequelae and preventive and/or treatment strategies.
RECENT FINDINGS: Definition of EIU and its conceptualization still requires refinement. Recent studies indicate a changing trend towards female predominance of EIU. Women also differ in their internet use compared with men regarding their preference in the internet content and online activities, motives of use and factors related to access to the internet, including the device, sociocultural restrictions, etc. The correlates and sequelae of EIU encompass psychological, physical, biological, family and social domains that could form the basis of identifying individuals at risk and strategizing treatment.
SUMMARY: The findings indicate the need for standardization in definition and measures of EIU for better recognition of EIU and identification of its at-higher-risk females. Effective preventive and treatment measures are still limited by various methodology flaws outlined here.

Fulltext Gender differences and psychological factors associated with suicidal ideation among youth in Malaysia

Ibrahim N, Amit N, Che Din N, Ong HC

Psychol Res Behav Manag, 2017;10:129-135.
PMID: 28496374 DOI: 10.2147/PRBM.S125176

Suicide is a global phenomenon that has been showing an upward trend in recent years. It is the second leading cause of death among youth. Studies on suicidal ideation warrant greater attention, as it leads to suicide attempts and other health risk behaviors. Thus, the objective of this study was to compare gender differences in suicidal ideation and determine the predictors of suicidal ideation among youth. This cross-sectional study was carried out among 232 youths aged between 15 and 25 years from selected urban areas in Malaysia. The results showed that suicidal ideation was higher among male participants compared with female participants. Age was the predictor of suicidal ideation for males, while depression and loss of motivation, as components of hopelessness, were the predictors of suicidal ideation among females. Hence, it is important that professionals conduct early identification tests for suicidality among young people. This will facilitate the early detection of depression and hopelessness, which is important, in order to prevent suicidal behaviors or other problems before these occur.

PMID: 11338745

There is no doubt that gender bias has been inherent in medical and public health education, research, and clinical practice. This paper discusses the central question for medical and public health educators viz. whether women's health concerns and needs could be best addressed by the conventional biomedical approach to medical and public health education, research, and practice. Gender inequalities in health and gender bias in medical and public health education are revealed. It is found that in most public health and prevention issues related to women's health, the core issue is male-female power relations, and not merely the lack of public health services, medical technology, or information. There is, thus, an urgent need to gender-sensitize public health and medical education. The paper proposes a gender analysis of health to distinguish between biological causes and social explanations for the health differentials between men and women. It also assessed some of the gender approaches to public health and medical education currently adopted in the Asia-Pacific region. It poses the pressing question of how medical and public health educators integrate the gender perspective into medical and public health education. The paper exhorts all medical and public health practitioners to explore new directions and identify innovative strategies to formulate a gender-sensitive curriculum towards the best practices in medicine and public health that will meet the health needs of women and men in the 21st century.

PMID: 7650778

In the past year, stool specimens of 1,732 alien laborers were examined for intestinal parasites. There was no significant difference in the positive rate between males and females. All alien laborers were examined in 3 hospitals and the positive rates were 24.8% (191/769), 13.6% (109/804) and 12.6% (20/159). Broken down by nationality, the positive rates in laborers from Thailand, Indonesia, the Philippines and Malaysia were 23.9% (192/803), 20.3% (62/305), 12.1% (60/498) and 4.8% (6/126) respectively. Of all alien laborers, 17.2% (297/1,732) had single infections of parasites and 1.3% (23/1,732) had multiple infections. Opisthorchis viverrinii was the most prevalent parasite found in infected alien laborers. 91.5% of alien laborers were aged from 21 to 40-years-old and had positive rates of parasites reaching 91.0%. The time of arrival in Taiwan had an effect in all alien laborers examined for parasites. The positive rate in laborers arriving during April to June was 22.7% which was significantly higher than the 16.3% for laborers arriving in other months.

Gendered burdens and impacts of SARS-CoV-2: a review

Ayittey FK, Dhar BK, Anani G, Chiwero NB

Health Care Women Int, 2021 2 23;41(11-12):1210-1225.
PMID: 33616506 DOI: 10.1080/07399332.2020.1809664

Using the SRQR EQUATOR checklist, we review the gendered burdens and impacts of SARS-CoV-2. Although men are primarily detected to be slightly more vulnerable in succumbing to the ongoing COVID-19 contagion, many researchers have recognized that women are facing more of the devastating brunt in secondary terms. Aside gendered health and social impacts, women are more disproportionately disadvantaged than men in economic terms, as they are predominantly found in the part-time and informal occupations, which have been closed down for months now since the emergence of the current global crisis. Also, since women form the vast proportion of the caregivers within the health sector, their role in handling the pandemic as frontline respondents at the hospitals put them in higher risks of contracting the disease. Despite this higher risk of infection, the peculiar attentions to women's health in the planning and rolling out of actions to contain the virus have been overlooked. Additionally, their unpaid domestic care works have also increased due to closure of schools and businesses, which have forced family members to stay at home for as long as movement control orders remain in place. In this confined state, the domestic violence against women have been recorded to be on the increase. To recommend measures that consider gendered dimensions of the current crisis, we have reviewed the various sex-based burdens and impacts of the pandemic, and proceeded to suggest necessary response actions to handle the situation. Particular emphasis is placed on the effects of the outbreak on women, and how the gendered flaws in the current response strategies could be avoided in managing future global crises.

PMID: 33597453

Fleas are the common cause of skin disorders in cats. They are well-known for transmitting various pathogens to both cats and humans. Accordingly, this study was conducted to gain insights on the risk factors associated with flea infestation on cats. Flea combing conducted on 426 cats from four distinct regions in Peninsular Malaysia revealed a relatively high rate of flea infestation on 306 cats (71.83%). A total of 651 fleas were collected, all of them were identified as Ctenocephalides felis with the total intensity of 2.13 and abundance of 1.53. The sex ratio of fleas was female-biased at 2.5:1 (♀=464, ♂=187). Statistical analysis of the data revealed that flea infestation was significantly (P<0.05) associated with several risk factors including region, age, weight, status (stray, sheltered, pet), body condition, and hair length. Higher flea prevalence was also observed in female cats (77.99%), big-sized cats (91.76%), stray cats (84.94%), cats with clean body condition (73.35%), and cats with long hairs (78.38%) as compared to their contemporaries within the same comparison variables. The high infestation of fleas in this study is indicative of cats as a flea reservoir particularly C. felis. Thus the findings of this study and the knowledge gained on the risk factors can be used to develop and improve control measures and management of flea infestations.

MyJurnal

Introduction: Domestic violence is a serious issue that has often been overlooked by the society. It includes any physical, emotional or sexual violence that occurs between family members. Year after year, many cases of domestic violence have been reported in news and the numbers keep increasing from time to time. Experiencing this violence may give negative impacts on the victim. This study aimed to determine the prevalence of domestic violence among university students in Selangor, Malaysia and to discover its effects on their academic achievement. Methods: A cross-sectional study was implemented in a form of questionnaire that was distributed to 368 university students at Selangor, Malaysia in the period from June 2018 to December 2018. Results: Results showed that 69 respondents (18.7%) had experienced DV throughout their life; all of them suffered physical violence, 95.7% had suffered emo- tional violence while 14.5% had suffered sexual violence. Age, gender, residence, family income, institution’s type and speciality of study has no significant association with DV while, race, religion and parents’ status were signifi- cantly associated with DV. Also it was noticed that out of these 69 respondents that had experience of domestic violence, 36 of them were studying in private universities and 33 of them were studying in public universities. Most of those experienced domestic violence showed low CGPA. Conclusion: It is concluded that there is low prevalence of DV among university students in Selangor. Experiencing DV during childhood has an impact on the academic achievement of the victim in the future university life.

PMID: 33973567 DOI: 10.47665/tb.38.2.031

Goat Warble Fly Infestation (GWFI) is also known as subcutaneous myiasis caused by Przhevalskiana silenus (Diptera: Oestridae). It is widely distributed in tropical and sub-tropical areas of the world. In goats, WFI is usually detected through conventional procedure which underestimated the infestation. The current study was designed to determine the serodiagonsis of GWFI (through IDEXX Hypodermosis serum antibody test) and also aimed to investigate its seroepizootiological profile in Pothwar region, Pakistan from 2013-14. The results showed that average seropositivity (ELISA kit) of GWFI was 18.5% whereas, it was 11% by using conventional procedure (Palpation method) depicting a significant difference (p<0.05). Higher seropositivity (30.8%) was observed in Jhelum district as compared to e Attock district (6%). The L1 larvae were found in September, while nodules start appearing in October to December and last until the end of February. The month wise peaks of optical density (OD) was higher in December which gradually decrease along with the end of winter season. The prevalence of GWFI revealed no significant difference among three host breeds (Jattal, Beetal and Tedy). According to the results, high infestation rate (28%) was observed in young animals of age group < 1 year as compared to old animals (> 2 years). Topographically, hilly areas (33%) provide favourable climatic conditions for the propagating of larval stages. Sex difference showed no significant difference. The seroprevalence varied significantly with respect to age, month, districts and topographical location. The current study proved that serologic diagnosis (commercial ELISA kit) as more sensitive and accurate for timely diagnosis of GWFI than traditional method. The information on the epizootiology of P. silenus in goats of Pothwar region would help in devising effective control strategies.

PMID: 33954025 DOI: 10.7717/peerj.10936

Sexual dimorphism is a common phenomenon in the animal kingdom. To test the consistency of sexual dimorphism patterns among sympatric species of the same genus, ten morphometric characteristics of mud crabs Scylla olivacea, S. tranquebarica and S. paramamosain were measured and compared using Discriminant Function Analysis (DFA). The descriptive analysis revealed that in all three species, body size dimensions and cheliped dimensions were significantly larger in males whereas the abdomen width was female-biased. Also, we described a morphological variation (carapace width, CW ≤ CW at spine 8, 8CW) that is unique to S. olivacea. Discriminant function analysis revealed that all nine morphometric characteristics were sexually dimorphic in S. olivacea, S. tranquebarica (except right cheliped's merus length, ML) and S. paramamosain (except 8CW). The obtained discriminant functions based on the morphometric ratios (with CW as divisor) correctly classified 100% of adults of known sex of all three species. Further, based on the selected body traits, DFA was able to almost completely distinguish males (94%), but not females (74%), among the three Scylla species. This study highlights that congeneric species of portunids (e.g., Scylla spp.) show similar sexually dimorphic characteristics (body size and secondary sexual characteristics).

This study examined the relationship between body dissatisfaction and eating disorder of undergraduate students in University Malaysia Terengganu (UMT). Using stratified random sampling technique, data from 299 respondents was gathered. Body dissatisfaction was measured using Body Shape Questionnaire while eating disorders were assessed using Eating Attitudes Test. Descriptive statistics showed thatthe majority of the respondents reported no symptom of body dissatisfaction. With regard to eating disorders, respondents reported low levels of dieting, bulimia and oral control, indicating that an eating disorder in this sample was somewhat low. T-test analyses showed that there were no significant gender differences in body dissatisfaction as well as in eating disorders. However, there was evidence to suggest that female respondents had slightly higher level of eating disorder than males. Results of Pearsoncorrelations showed there was significant relationship between body dissatisfaction and total score of eating disorders, dieting, bulimia and oral control subtypes (r = .58, p

Fulltext Validation and Measurement Invariance of the Body Appreciation Scale-2 between Genders in a Malaysian Sample

Tan CS, Cheng SM, Cong CW, Abu Bakar ARB, Michael E, Mohd Wazir MIB, et al.

Int J Environ Res Public Health, 2021 11 05;18(21).
PMID: 34770142 DOI: 10.3390/ijerph182111628

The 10-item Body Appreciation Scale-2 (BAS-2) is a measurement for individuals to self-report the extent to which they accept and respect their bodies. Although the BAS-2 has been translated into the Malay language and found to have promising qualities, the psychometric characteristics of the English version of BAS-2 remain unknown in the Malaysian context. The present study thus administered the English version BAS-2 and selfie-editing frequency scale to 797 individuals aged 18 to 56 years old in Malaysia. The dataset that was randomly divided into two halves were submitted to exploratory factor analysis and confirmatory factor analysis respectively. Both of the factor analyses consistently support a one-factor model. The Cronbach's alpha and McDonald omega coefficients were greater than 0.90, indicating that the BAS-2 has good internal consistency. The incremental validity is also evident. A hierarchical multiple regression showed that the BAS-2 score had a positive relationship with selfie-editing frequency after controlling for age and gender. Moreover, the measurement invariance test supported scalar invariance between genders, and an analysis of covariance did not find significant gender differences. Overall, the findings replicate past findings and regularly support the usability of the BAS-2 in the Malaysian context. The implications of the BAS-2 and future directions are also discussed.

Postural stability is crucial in maintaining body balance during quiet standing, locomotion, and any activities that require a high degree of balance performance, such as participating in sports and dancing. Research has shown that there is a relationship between stability and body mass. The aims of this study were to examine the impact that two variables had on static postural control: body mass index (BMI) and gender. Eighty healthy young adults (age=21.7±1.8 yr; height=1.65±0.09 m; mass=67.5±19.0 kg) participated in the study and the static postural control was assessed using the Biodex Balance System, with a 20 Hz sampling rate in the bipedic stance (BLS) and unipedic stance (ULS) for 30s. Five test evaluations were performed for each balance test. Postural control was found to be negatively correlated with increased adiposity, as the obese BMI group performed significantly poorer than the underweight, normal weight and overweight groups during BLS and ULS tests. The underweight, normal weight and overweight groups exhibited greater anterior-posterior stability in postural control during quiet stance. In addition, female displayed a trend of having a greater postural sway than male young adults, although it was evidenced in only some BMI groups. This study revealed that BMI do have an impact on postural control during both BLS and ULS. As such, BMI and gender-specific effects should be taken into consideration when selecting individuals for different types of sporting activities, especially those that require quiet standing.

Rahman MS, Mohamad OB, Zarim Zb

Glob J Health Sci, 2014 Apr 16;6(4):196-204.
PMID: 24999143 DOI: 10.5539/gjhs.v6n4p196

In recent time climate change and its impact on human health and awareness constitute a set of complex and serious consequences to be tackled by an individual country. Climate change is not merely an environmental issue, but also it is a threat that goes beyond national borders. The purpose of this study is to identify the awareness and the impact of climate change, perceived by the young citizens in Malaysia by focusing on gender differences. Based on a survey of 200 respondents from different public and private University's students in Malaysia, this research used descriptive statistics and T-test to look into the research objective. The results revealed media can play an important role in the awareness of climate change. Meanwhile the male respondents have shown considerable attention on the physical impact of climate change like heat related stress. On the other hand female respondents have shown considerable attention to the psychological impact by the climate change. From a pragmatic perspective, the findings from this research will assists the policy makers to understand more about the perceived awareness on the climate change issues of the young citizens which ultimately assist them to inaugurate new initiatives to confront the challenges of climate changes. This research is among the pioneer study on the issue of the perceived awareness in regards to climate change in Malaysia by focusing on gender differences.

Sien YP, Sahril N, Abdul Mutalip MH, Zaki NA, Abdul Ghaffar S

Asia Pac J Public Health, 2014 Sep;26(5 Suppl):36S-43S.
PMID: 25070694 DOI: 10.1177/1010539514543681

Dietary supplements use is relatively widespread in some countries but knowledge of supplements consumption in Malaysia is limited, more so among adolescents. This study aimed to investigate the determinants of dietary supplements use among Malaysian adolescents using multiple logistic regressions analysis. Data from the Malaysia School-based Nutrition Survey 2012 based on a 2-stage stratified sampling was used. The prevalence of vitamin/mineral supplements and food supplements intake among adolescents was 54.1% and 40.2%, respectively. Usage was significantly higher among younger adolescents and among boys. Dietary supplements were also taken mostly by those who thought they were underweight. The most common vitamin/mineral supplements and food supplements consumed were vitamin C and bee products. The main reason for taking supplements was parents' instruction. These findings can be useful for developing health communications on supplement use targeted to adolescents and their parents.

J Egypt Soc Parasitol, 2013 Dec;43(3):561-8.
PMID: 24640856

The current study determined the prevalence of intestinal protozoan infections among the Orang Asli schoolchildren in Pos Senderut, Pahang, Malaysia. The overall intestinal protozoan infection rate was 85% (261 out of 307). The highest prevalence rates were due to Entamoeba coli (24.4%), Giardia lamblia (21.8%), Blastocystis hominis (21.2%) and Entamoeba histolytica (15.0%). The prevalence of Iodamoeba butschlii was only 2.9%. Among the positive samples, mixed infection with B. hominis and E. histolytica was 3.3%, B. hominis and G. lamblia was 2.9%, G. lamblia and E. histolytica was 2.0% and triple infections (B. hominis, G. lamblia and E. histolytica) was 1.0 %. The prevalence of the infection was high in all age groups (6-14 years old). Thus, we can conclude that intestinal protozoan infections are still representing a serious public health problem in aboriginal communities, especially among children.
