Anthropometry and body composition of adolescents in Cracow, Poland

The aim of the present study was to determine the level of adiposity and obesity in Polish adolescents and compare the results with earlier studies conducted in this population as well as those carried out in other populations.The study group consisted of 456 boys and 514 girls aged 14-18 years living in Cracow chosen from randomly selected secondary schools. Weight, height, waist, and hip circumference (WC, HC) as well as triceps, biceps, subscapular, and suprailiac skinfold thickness (SFT) were measured. Body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), subscapular/triceps skinfold ratio (STR), and percentage body fat were computed. The prevalence of overweight and obesity based on Polish children growth reference were calculated and age-dependent and gender-specific smoothed percentile curves for BMI and ROC curves were generated.Weight, height, WC, HC (up 16yr), WHtR (up 15yr), and WHR were considerably higher in males than females. Weight, height, and HC increased with age; WHtR remained the same. The prevalence of overweight and obesity were 10.2% (boys 10.3%; girls 10.1%) and 4.2% (boys 5.3%; girls 3.3%). ROC analysis revealed that WHtR was the best tool for detection of obesity (AUC of 0.982±0.007) in males, whereas the sum of four SFTs (AUC: 0.968±0.011) and WHtR (AUC: 0.963±0.012) were the best predictors of obesity in females.The level of adiposity in Cracow adolescents increased during the last decade. However, it is still lower than in other well-developed societies struggling with obesity epidemics

Psychometric assessment of the Polish translation of the Transgender Positive Identity Measure (TPIM)

Aim. Research conducted in transgender and gender diverse individuals focuses mainly on the challenges and health disparities affecting this population. One reason for this situation is the lack of questionnaires capturing positive aspects and experiences related to being a transgender person. The Transgender Positive Identity Measure (T-PIM) is one of a very few measures designed to explore such experiences. The aim of the study was to investigate the structure, reliability, and validity of the Polish translation of the T-PIM questionnaire. Method. A group of 89 transgender and gender diverse participants completed an online survey including the T-PIM questionnaire, Resilience Measurement Scale (SPP-25) and the Center for Epidemiologic Studies Depression Scale - Revised (CESD-R). Hierarchical item clustering method (ICLUST), Horn’s parallel analysis and Velicer’s minimum average partial test (MAP) were employed to investigate the structure of the questionnaire. Results. The analyses showed that the Polish translation of the T-PIM questionnaire was characterized by a 5-factor structure consistent with the original publication (Authenticity, Intimacy, Community, Social Justice, Insights). Cronbach’s alpha and Guttman’s lambda-6 reliability coefficients reached satisfactory levels for all five factors and for the whole questionnaire. Conclusions. The Polish translation of the T-PIM questionnaire is characterized by satisfying psychometric properties and can be used in studies on transgender and gender diverse communities

It gets better with age : Resilience, stigma, and mental health among lesbian, gay, bisexual, transgender and queer persons from Poland

Lesbian, gay, bisexual, transgender, and queer populations are disproportionately affected by chronic stress associated with stigma which contributes to health adversities including depression. Negative impact of stigma on health can be alleviated by factors such as resilience. Little is known however on how exposure to stigma, protective factors and mental health change with age among gender and sexually diverse persons. Our study aimed at investigating this issue. Our sample consisted of (i) 245 sexually diverse cisgender women, (ii) 175 sexually diverse cisgender men, and (iii) 98 transgender and gender diverse persons. We collected data through a web-based survey. Linear regression models were performed to investigate the interactions of age and each group of participants for resilience, stigma exposure, and mental health indicators (depression and self-esteem). We hypothesized that resilience and mental health indicators will be positively associated with age in all distinguished groups despite the continued exposure to minority stress. The analysis yielded no significant relationships between stigma exposure and age among study participants. However, we observed significant interaction effects of distinguished groups of participants and age in case of self-esteem, depression, and resilience. Self-esteem and resilience were related positively, and depression was negatively associated with age in all study groups. Additionally, we observed that sexually diverse cisgender men demonstrated significantly increased resilience, reduced depression and higher self-esteem compared to other groups. Although the exposure to stigma did not decrease with age, resilience and self-esteem increased, suggesting that LGBTQ persons manage to thrive despite adversities
