Sex And Age Differences

This study examined the effects of sex and age on scores on a matrices test among university and college students aged 17 to 51 yr. Sex differences in mean scores were nonsignificant. The general decline with age was linear and negative, significantly so for women ( n = 132), not for men ( n = 74). Significant decrements occurred from the age of 26 yr. upwards for women only. The findings suggest that loss of intellectual capacity on the Raven's Matrices can be attributed to age.

Main Effects

College students heard 36 taped verbal evaluations (reinforcers) representing all combinations of three levels of content and three of intonation (positive, neutral and negative in each case). Ss rated each reinforcer on three 5-point scales concerning its meaning as (1) a comment about performance, (2) a producer of a feeling-state in the recipient, and (3) an expression of the speaker's liking or disliking of the recipient. Content and intonation had significant main effects and interactions for every rating, but their relative effects differed across ratings. Content was strongly dominant for judgments of “objective” meaning, and moderately dominant for judgments about the recipient's feeling, while intonation was dominant for judgments about the speaker's liking for the recipient. No sex differences and only slight age differences were found.

When face processing studies find sex differences, male infants appear better at face recognition than female infants, whereas female adults appear better at face recognition than male adults. Both female infants and adults, however, discriminate emotional expressions better than males. To investigate if sex and age differences in facial scanning might account for these processing discrepancies, 3–4-month-olds, 9–10-month-olds, and adults viewed faces presented individually while an eye tracker recorded eye movements. Regardless of age, males shifted fixations between internal and external facial features more than females, suggesting more holistic processing. Females shifted fixations between internal facial features more than males, suggesting more second-order relational processing, which may explain females’ emotion discrimination advantage. Older male infants made more fixations than older female infants. Female adults made more fixations for shorter fixation durations than male adults. Male infants and female adults’ greater encoding of facial information may explain their face recognition advantage.

Sex And Age Differences

AbstractThe aim of this research was to analyse variation in body image perception and satisfaction by age, sex and nutritional status in an adult sample from the Basque Country, Spain. A case-control study was performed for 227 women and 178 men aged 18–70 years. Stunkard’s silhouettes were used to evaluate Current Body Image (CBI) and Ideal Body Image (IBI), as well as dissatisfaction and inconsistency scores. Nutritional status was assessed following the WHO criteria for BMI in an adult population. The sample was divided into four groups based on sex and age (early adulthood <45 years, and middle/older adulthood ≥45 years). The Mann–Whitney U test was employed to evaluate sex and age differences, and the Gamma coefficient to assess the association between body image variables and nutritional status. Significant age differences in CBI (p<0.05) and sex differences in IBI (p<0.001) were detected. Both variables showed a positive association with BMI (p<0.01), which indicates that BMI is a biological characteristic related to body image satisfaction and influences participants’ perception of themselves. Dissatisfaction scores showed that both sex and age differences (p<0.05) were negatively associated with BMI (p<0.001). Only participants ≥45 years presented sex differences in inconsistency scores (p<0.05); this variable was associated with BMI in women (p<0.01). Preferences in body image showed sexual dimorphism, with women preferring thinner bodies than men – a pattern observed in many Western populations – linked in part to sociocultural pressures. Women were more dissatisfied with their bodies than men; a higher dissatisfaction was observed in older relative to younger participants. The results confirm the association between nutritional status and body size perception and satisfaction, but also the relationship between nutritional status and the reliability with which women can classify themselves; in men, this relationship was not as clear.

Abstract Aim: To examine the magnitude of sex differences in survival from the Coronavirus Disease 2019 (COVID-19) in Europe across age and countries. We hypothesise that men have higher mortality than women at any given age, but that sex differences will decrease with age as only the strongest men survive to older ages.Methods: We used population data from Institut National D’Études Démographiques on cumulative deaths due to COVID-19 from February to June 2020 in 10 European countries: Denmark, Norway, Sweden, The Netherlands, England & Wales, France, Germany, Italy, Spain and Portugal. For each country, we calculated cumulative mortality rates stratified by age and sex and corresponding relative risks for men vs. women.Results: The relative risk of dying from COVID-19 was higher for men than for women in almost all age groups in all countries. The overall relative risk ranged from 1.11 (95% CI 1.01-1.23) in Portugal to 1.54 (95% CI 1.49-1.58) in France. In most countries, sex differences increased until ages 60-69 years, but decreased thereafter with the smallest sex difference at ages 80+.Conclusions: Despite variability in data collection and time coverage among countries, we illustrate an overall similar pattern of sex differences in COVID-19 mortality in Europe.

Sex And Age Differences

It is commonly believed that depression is more common in females than in males. A quantitative synthesis of published research showed, however, that the sex difference is age specific. There is little sex difference in either childhood or advanced old age, but a notable sex difference in middle life. This sex difference appears because rates for females rise sharply from childhood to adulthood and then decline somewhat in old age. By contrast, rates for males show a small rise in early adulthood but are otherwise fairly stable throughout life. The age-specific nature of these sex differences may be explainable in terms of differences in social roles at various ages.

Sex And Age Differences

Background: Evidence on youth suicides from Southeastern Europe is scarce. We are not aware of previous reports from Bosnia and Herzegovina, which experienced war from 1992 to 1995. Durkheim’s theory of suicide predicts decreased suicide rates in wartime and increased rates afterward. Aims: To compare child and adolescent suicides in Bosnia and Herzegovina before and after the war. Methods: Data on youth suicide for prewar (1986–90) and postwar (2002–06) periods were analyzed with respect to prevalence, sex and age differences, and suicide methods. Suicide data from 1991 through 2001 were not available. Results: Overall youth suicide rates were one-third lower in the postwar than in the prewar period. This effect was most pronounced for girls, whose postwar suicide rates almost halved, and for 15–19-year-old boys, whose rates decreased by about a one-fourth. Suicides increased among boys aged 14 or younger. Firearm suicides almost doubled proportionally and were the predominant postwar method, while the most common prewar method had been hanging. Conclusions: The findings from this study indicate the need for public education in Bosnia and Herzegovina on the role of firearm accessibility in youth suicide and for instructions on safe storage in households. Moreover, raising societal awareness about suicide risk factors and suicide prevention is needed.

Two Factors

Walder's peer nomination inventory was given to elementary school children and college students and the data analyzed for age differences. The first two factors are essentially the same as Walder's factors and are unaffected by Ss age. The third child factor is similar to Walder's third factor of socially undesirable non-aggressive traits but is better differentiated and more general, including several items measuring rebelliousness. Two additional factors appear in the adult sample, one defined by rebellion and rejection items and one by dominance items.
