Abstract The prevalence of low birth weight (LBW) is high in Bangladesh, but no study has collated recent estimates of LBW prevalence from throughout the country. The aim of this meta-analysis was to evaluate the prevalence of LBW and birth weight status in Bangladesh. We searched PubMed, Medline, Ovo and Google Scholar to find published articles in national and international journals from 2000–2020 and reviewed for relevance. Meta-analysis and Q test were performed to estimate the prevalence and heterogeneity of LBW from all included articles. Meta-regression was done to quantify associations with sample size and study year. Stratified analysis was conducted and effect size calculated for differences in LBW prevalence by sex, division and urban/rural area. In total 48 studies with 166,520 births were found and included in this meta-analysis. The pooled prevalence of LBW was 29.1% (95% CI, 28.9–29.3%) in overall, 29.9% (29.7–30.2%) in rural and 15.7% (14.9–16.6%) in urban areas. There was no significant difference in average birth weight between boys and girls (SD, 0.71; 95% CI, −0.43–1.83). Prevalence of LBW was higher in north-east Bangladesh compared to other zones (p<0.05). The pooled prevalence of LBW did not change significantly for last two decades. The prevalence of LBW in Bangladesh remains high. Lack of improvement suggests an urgent need for scaled up maternal and prenatal interventions and services known to reduce LBW. Urban/rural and divisional differences in rates suggest areas of greatest need.

Abstract The paper aims to study intragroup variation inside the two pre-Columbian Cuban populations: the aceramic Archaic and the ceramic Taino groups, based on their cranial morphology. The latter applied artificial cranial deformation to all its members, so the groups are referred to as “non-deformed” and “deformed” samples here. Studies across different disciplines suggest evidence of cultural and biological diversity inside the non-deformed group, while local variations of applying the deforming device can be responsible for shape variation across the deformed group. Cranial metrics and non-metric cranial traits of the 92 crania of Cuban origin were analyzed, although the sample size varied between the analyses due to the incompleteness of the crania. Geometric morphometrics was applied to the deformed crania to study the shape variation across the sample. Three deformed crania from the Dominican Republic were analyzed together with the deformed Cuban sample to test the variability of the practice between the islands. Principal component analysis and the Mantel test did not reveal any geographic differences in the cranial metric traits. No morphological differences associated with the antiquity of materials could be seen either based on the available data. The principal component analysis of the Procrustes coordinates of the cranial vault outline in the lateral norm revealed continuous variability of cranial shapes from the ones with more flattened frontal and occipital bones to the more curved outlines, which is probably explained by individual variation. Non-metric traits variation revealed bilateral asymmetry in the expression of the occipito-mastoidal ossicles among the deformed crania. In conclusion, the study did not support assumptions about morphological diversity inside the studied samples or proved the impossibility of available craniological data to reflect possible intragroup differentiation at the moment.

Abstract Mid-upper arm circumference (MUAC) is an alternative anthropometric measurement to assess undernutrition but a universally accepted cut-off is yet to be established. The objectives of the present study are to determine whether the proposed sex-specific global cut-offs are suitable across several tribes in India. This cross-sectional study was conducted among nine tribal populations in India (1046 males, 1087 females). Weight, height and MUAC values were obtained, and body mass index (BMI) was calculated. The BMI cut-off (<18.5 kg/m2) was used to determine chronic energy deficiency (CED). The ROC Curve analyses of binomial logistic regression for MUAC versus CED revealed optimal cut-off point of MUAC as 23.8 cm (in males) and 21.8 cm (in females). MUAC cut-offs were similar in females, relative to males, in all tribes. Males with MUAC<24cm and females with MUAC<22 encompassed significantly higher numbers of CED than those with MUAC≥24 and ≥22 cm, respectively (χ2-value males: 254.9, p<0.001; females: 493.60, p<0.01). A single cut off point of MUAC may not be universally applicable for diverse populations and both sexes as well. It seemed that there is no alternative than to undertake further validation studies in various populations before using the MUAC cut off to identify undernourished or CED condition.

Abstract Gaming related experiences and addictive behaviours are emerging causes of adverse psycho-social health such as depression, anxiety, in adolescents and young adults around the world. Nonetheless, there remains a dearth of information relating to adolescents and young adults in India, a country which has millions of gamers. Present study examined the effects of massively multiplayer online role-playing games on the psychological health and inter-personal relationships of adolescents and young male adults of sub-urban Kolkata, West Bengal, India. Questionnaires were used to collect data on socio-economic and lifestyle traits, psychological health and inter-personal relationships were obtained from both gamers (n = 150) and non-gamers (n = 150). Data on gaming experiences and addiction were obtained only from gamers. MANCOVA and linear regression were performed to understand the effects of socio-economic and lifestyle traits, gaming experience and addiction traits on psychological health and inter-personal relationships of gamers. Study findings revealed that both gamers and non-gamers derived from a similar age group (mean age = 19.94 years) and socio-economic cluster. Disparities in psychological health in terms of depression, anxiety and stress and inter-personal relationship in terms of parent and peer attachments were present across social groups and between gamers and non-gamers. Various problematic gaming experiences and gaming related addictive behaviours resulted in poor psychological health and inter-personal relationship with parents and peers. Male gamers were at high risk to develop adverse psychological health and poor inter-personal relationships with parents and peers due to problematic gaming experience and gaming addiction. Proper education and counselling regarding the beneficial and detrimental sides of gaming may ensure better psycho-social health of adolescents and young adults in India.

Abstract The present cross-sectional study is an attempt to understand the effect of body mass index (BMI) on the prevalence of various symptoms of polycystic ovary syndrome (PCOS) and to evaluate its associated risk factors. A total of 250 PCOS women diagnosed by Rotterdam Criteria (2003), age ranging from 18–45 years, attending OPD of Gynaecology and Obstetrics of PGIMER, Chandigarh, India were enrolled in the study. All the participants were divided in three groups according to their body mass index (BMI). The polycystic ovaries (83.2%) were the most frequently occurring symptoms of PCOS followed by hirsutism (74.4%), oligomenorrhea (60%), seborrhea (45.2%) and acne (40%). Category wise frequency distribution showed higher prevalence of symptoms among women in overweight/obese category, which were further supported by correspondence analysis. Results of multivariate analysis revealed that marital status, type of diet, socio-economic status and physical activity level were potential risk factors contributing to severe manifestations of PCOS symptoms. Obesity denoted as an important risk factor can exaggerate many symptoms of PCOS and also be a causative factor for menstrual disturbance.

Abstract The aim of this paper is to review recent hypotheses on the evolutionary origins of music in Homo sapiens, taking into account the most influential traditional hypotheses. To date, theories derived from evolution have focused primarily on the importance that music carries in solving detailed adaptive problems. The three most influential theoretical concepts have described the evolution of human music in terms of 1) sexual selection, 2) the formation of social bonds, or treated it 3) as a byproduct. According to recent proposals, traditional hypotheses are flawed or insufficient in fully explaining the complexity of music in Homo sapiens. This paper will critically discuss three traditional hypotheses of music evolution (music as an effect of sexual selection, a mechanism of social bonding, and a byproduct), as well as and two recent concepts of music evolution - music as a credible signal and Music and Social Bonding (MSB) hypothesis.

Abstract The aim of the study was to establish the degree of robustness and to infer the level of mobility of a group from ancient Thebes (Middle Egypt). Seventy-one left femurs of adult individuals from the 1st century AD from the tomb of Monthemhat (Luxor) were studied. Metrical, non-metrical variables, shape and size indices of femur were considered. Stature, body mass and Body Mass Index were calculated. All variables showed higher values in males, the vertical diameter of the femoral head was the variable with the highest sexual dimorphism. Non-metric variables also indicated low robustness, with heterogeneous sex distribution. The robustness, pilastric and platymeric indices indicated that the values were close to those of gracile populations in both sexes. Subtrochanteric size and shape showed no sexual dimorphism. The robustness, size and shape in the middle of the diaphysis suggested a mobility related to a daily occupation without intense physical activity in the legs. The results indicate a profile of low robustness, relative sedentarism with apparent sexual division in daily activities.

Abstract The relationship between maternal age and the occurrence of cerebral palsy is still highly controversial. The aim of the study was to examine the effect of maternal age on the risk of CP development, taking into account all significant risk factors and the division into single, twin, full-term, and pre-term pregnancies. The survey covered 278 children with CP attending selected educational institutions in Poland. The control group consisted of data collected from the medical records of 435 children born at Limanowa county hospital, Poland. The analyses included socio-economic factors, factors related to pregnancy and childbirth, and factors related to the presence of comorbidities and diseases in the child. Constructed logistic regression models were used for statistical analyses. For all age categories included in the estimated models (assessing the effect of demographic factors on the development of CP), only the category of ≤24 years of age (in the group of all children) was significant. It was estimated that in this mother’s age category, the risk of CP is lower (OR 0.6, 95% CI: 0.3–1.0) in comparison to mothers aged 25-29 (p = 0.03). However, estimation with the use of a complex logistic regression model did not show any significant effect of maternal age on the incidence of CP in groups from different pregnancies types. It became apparent that maternal age is a weak predictor of CP, insignificant in the final logistic regression model. It seems correct to assume that the studies conducted so far, showing a significant effect of maternal age in this respect, may be associated with bias in the estimators used to assess the risk of CP due to the fact that other important risk factors for CP development were not included in the research.

Abstract We compared the perception of two ethnic groups in relation to health, obesity and blood pressure problems and its management, and to compare the body fat patterning and blood pressure levels between Rai and Lepcha ethnic groups. We chose Rai and Lepcha ethnic groups living in Ranka, a place which is 16 kilometres away from the city of Gangtok, Sikkim. The study involved 160 males (Rai = 80 and Lepcha = 80) of age 25–35 years. The participants were initially interviewed about their perception towards health, obesity and blood pressure problems and its management along with other socio-demographic and lifestyle variables. Later, body fat patterning and blood pressure levels of the participants were measured and compared between these two groups. Multiple linear regression analysis was performed to understand the association of body fat patterning and blood pressure levels with socio-demographic and lifestyle variables. Multivariate analysis of covariance (MANCOVA) was used to examine the relationship of ethnicity with both body fat patterning and blood pressure levels. We found a noticeable difference between Lepcha and Rai ethnic groups in perception towards health and obesity, blood pressure problems and its management. Similarly, a significant difference was observed in body fat patterning and blood pressure levels between Rai and Lepcha participants. MANCOVA revealed that the measures of body fat pattering and blood pressure levels differed significantly between these two ethnic groups, after controlling for lifestyle variables and age of the participants at time of interview. We concluded that there remains ethnic diversity, embedded in cultural behaviours and practices concerning health and obesity, hypertension and associated lifestyle patterns. Such practices, rooted in the belief system of an ethnic group is likely to inform the health condition of group members.

We chose Rai and Lepcha ethnic groups living in Ranka, a place which is 16 kilometres away from the city of Gangtok, Sikkim. The study involved 160 males (Rai = 80 and Lepcha = 80) of age 25–35 years. The participants were initially interviewed about their perception towards health, obesity and blood pressure problems and its management along with other socio-demographic and lifestyle variables. Later, body fat patterning and blood pressure levels of the participants were measured and compared between these two groups.
