Is Self-Reported Morbidity Associated with Nutritional Status? A Community-Based Study Among Urban Slum Dwelling Adult Males in West Bengal, India
Self-reported morbidity (SRM) is used in public health studies to assess community health profile and awareness. SRM was associated with socioeconomic status more sensitively than objective health measures. However, its usefulness was critically questioned for the plausible bias of subjective social experience. The present study assessed whether anthropometric profile, as objective marker of health, significantly varied according to SRM status am…
Factors affecting stunting among 3–12 years old girls of Purba Medinipur, West Bengal, India
Stunting is the impaired growth and development in children caused due to poor nutrition, recurrent infections and lack of psychosocial stimulus. Because stunting affects physical development and inhibits the child from attaining his full cognitive development as an adult, children may never regain the height lost due to stunting. Stunting (Low height-for-age) in infants and young children is a simple, wellknown indicator of undernutrition. The c…
Level of oxytocin prior to rugby and handball matches
The aim of the present exploratory study was to assess the changes in urinary oxytocin (OT) concentration during the period between five days before, and on the day of match, among rugby and handball players. Nine male rugby players with a mean age of 27.62 years (SD = 4.21) and 18 male handball players with a mean age of 17.03 years (SD = 0.57) participated. Urinary oxytocin level was measured by ELISA immunoassay as a ratio to the concentration…
Diversity of change in body mass index and skinfold thickness between different study courses within four years of study among the male students in a university in Poland
Objective: This study examined whether there were significant changes (expectedly increase) in BMI (Body Mass Index), and relative subcutaneous body fat during the four years of study in a university and compared these changes between the students of different courses, viz., Computer science, Law and administration, Humanities and Physical education. Design: This was a prospective follow up study with measurements at two time points with gap of f…
Is digit ratio (2D)
Human females demonstrate higher religiosity than men in populations. Digit ratio (2D:4D), being a putative indicator of prenatal testosterone, is associated in varying degrees with characters that show sexual dimorphism. A small number of studies have indicated that religiosity may be associated with the biological basis of sex differences in humans. The objective of the present study was to ascertain whether 2D:4D in religiously oriented semina…
Determining a global mid-upper arm circumference cut-off to assess underweight in adults (men and non-pregnant women)
Objective: To determine if a global mid-upper arm circumference (MUAC) cut-off can be established to classify underweight in adults (men and non-pregnant women). Design: We conducted an individual participant data meta-analysis (IPDMA) to explore the sensitivity (SENS) and specificity (SPEC) of various MUAC cut-offs for identifying underweight among adults (defined as BMI 2 ). Measures of diagnostic accuracy were determined every 0·5 cm across MU…
Is digit ratio (2D
The 2nd to 4th digit ratio (2D:4D) is a sexually dimorphic trait determined by the relative balance of prenatal testosterone (T) and oestrogen during the intrauterine development of foetus. Males on average have relatively lower 2D:4D than women in population. Lower 2D:4D is very often linked with greater physical ability, strength, superior sporting performance and many personality traits and behaviours which are seen more among the males. Recen…
Further Evidence of an Association Between Low Second-to-Fourth Digit Ratio (2d
Males and females differ in their preference for occupations and sporting activities, and differ also in risk-taking attitudes. In addition to other explanations, prenatal hormone exposure has been implicated in these gender-associated differences. The ratio of the relative lengths of the second-to-fourth digits (2D:4D) is a proxy indicator of prenatal exposure to testosterone relative to oestrogen. The 2D:4D ratio has been found to be associated…
The validity of mid-upper arm circumference as an indicator of low BMI in population screening for undernutrition
Objective To explore the possibility for a statistically appropriate value of mid-upper arm circumference (MUAC) to identify the state of severe undernutrition, based on very low BMI, among adult Indian slum dwellers. Design Cross-sectional study on adults. Height and MUAC were recorded and BMI was computed. Chronic energy deficiency (CED) was determined using the WHO international guidelines as BMI 2 and normal as BMI≥18·5 kg/m 2 . Besides calcu…
Sports Preference and Digit Ratio (2d
Humans exhibit sex differences in competitiveness, sensation seeking and risk-taking attitude, which are required in sports. These attributes are often linked to prenatal testosterone (PT) exposure. The second-to-fourth digit length ratio (2D:4D) is an indicator of PT exposure. A lower 2D:4D indicates higher PT exposure and vice versa. Males generally have a lower 2D:4D than females. Sensation- and/or thrill-seeking behaviours have also been foun…
Sex Differences in Digit Ratio (2d
The ratio of second-to-fourth digit length (2D:4D), which is generally higher in women compared with men, is a putative marker of prenatal testosterone (PT) exposure. Lower 2D:4D is linked with greater physical ability and strength, better sporting performance and a propensity towards jobs demanding greater physical ability. The objectives of this paper were to examine the sexual dimorphism in 2D:4D in both hands 1and compare this dimorphism in t…
Second to fourth digits ratio (2D
This aims of this research are to determine if the 2D:4D digit ratio is related to subjective pain experience during tattooing and to examine gender differences therein. The study involved 43 male and 28 female Polish adults recruited from two tattoo salons in Wroclaw and Leszno in Western Poland. These subjects were asked if they felt pain during their tattooing and answers were recorded as ‘Yes’ or ‘No’. The ventral surface lengths of the secon…
Sibling Composition and Household Room Sharing Are Associated with Menarcheal Status among Rural Bengalee Girls of West Bengal, India
Menarche, the first menstruation, is one of the most important events in a woman's reproductive life. The timing of menarche varies across populations and depends upon social interaction and family environment. It is also associated with several biological as well as social factors. The objective of this study was to explore the relationship between sibling composition and age at menarche (AAM) and to assess the association between the pattern of…
Relationship of family income and house type to body mass index and chronic energy deficiency among urban Bengalee male slum dwellers of Kolkata, India
Mid-upper arm circumference as a measure of nutritional status among adult Bengalee male slum dwellers of Kolkata, India
This cross-sectional study was undertaken to investigate the relationship of mid-upper arm circumference (MUAC) with body mass index (BMI) and the self reported morbidity status. This was to assess the reliability of MUAC as a measure of nutritional and overall physical health status among the adult (> 18 years) Bengalee male slum dwellers of Kolkata, (India). Data on height, weight, MUAC and self reported morbidity were analysed for 474 individu…
