Concordance between self-reported body mass index with weight perception, self-rated health and appearance satisfaction in people living in Tehran.

ABSTRACT: Obesity is investigated as a health concern due to high prevalence in the world. Nowadays, researchers are looking for an indirect method to measure weight and height. Self-reported Body Mass Index (BMI) is ever more served as an alternative method for direct weight and height measurement. Misreporting is a usual concern in self-reported BMI, thus, this study set explored the association and degree of agreement of self-reported BMI with weight perception, Self-Rated Health (SRH), and appearance satisfaction in people living in Tehran, Iran.722 men and women (268 men and 454 women) aged 30-64 years were selected using Cluster Multi-stage Sampling with the Probability Proportional to Size (PPS) method from each area. The questionnaire included demographic and socioeconomic variables and self-reported weight and height and questions related to weight and health perception, and appearance satisfaction. Independent samples T-test compared the mean of scales and differences in characteristics between BMI categories, analyzed using chi-square test. The Cohen's kappa coefficient examined the association between self-reported BMI and weight perception, SRH, and appearance satisfaction.The mean self-reported weight was 80.79 ± 12.87 in men and 68.33 ± 11.53 in women. The results of the agreement analysis for weight perception were Kappa = 0.38 with p < 0.0001 for women and Kappa = 0.23 with p <0.0001 for men. This measure of agreement, while statistically significant, is fair agreement. SRH and appearance satisfaction were not significantly correlated with self-reported BMI.The measurements of height and weight can cause significant imprecisions in calculation of BMI, which is used as a guide for identifying persons at risk of disease. Direct measurement of height and weight should be performed whenever possible for optimal measurements in clinical practice and clinically oriented researches.

Project description:BackgroundFollowing the outbreak of the COVID-19 pandemic, several clinical trials have evaluated postexposure prophylaxis (PEP) among close contacts of an index individual with a confirmed SARS-CoV-2 infection. Because index individuals do not directly inform the efficacy of prevention interventions, they are seldom enrolled in COVID-19 PEP studies. However, adjusting for prognostic covariates such as an index individual's COVID-19 illness and risk behaviors can increase precision in PEP efficacy estimates, so approaches to accurately collecting this information about the index individual are needed. This analysis aimed to assess whether surveying household contacts captures the same information as surveying the index individual directly.MethodsREGN 2069/CoVPN 3502, a randomized controlled trial of COVID-19 PEP, enrolled household contacts of SARS-CoV-2 index individuals. CoVPN 3502-01 retrospectively enrolled and surveyed the index individuals. We compared responses to seven similar questions about the index individuals' transmission cofactors that were asked in both studies. We estimated the percent concordance between index individuals and their household contacts on each question, with 50% concordance considered equivalent to random chance.ResultsConcordance between index individuals and contacts was high on the most objective questions, approximately 97% (95% CI: 90-99%) for index individual age group and 96% (88-98%) for hospitalization. Concordance was moderate for symptoms, approximately 85% (75-91%). Concordance on questions related to the index individual's behavior was only slightly better or no better than random: approximately 62% (51-72%) for whether they received COVID-19 treatment, 68% (57-77%) for sharing a bedroom, 70% (59-79%) for sharing a common room, and 49% (39-60%) for mask wearing at home. However, while contacts were surveyed within 96 h of the index individual testing positive for SARS-CoV-2, the median time to enrollment in CoVPN 3502-01 was 240 days, which may have caused recall bias in our results.ConclusionsOur results suggest a need to survey index individuals directly in order to accurately capture their transmission cofactors, rather than relying on their household contacts to report on their behavior. The lag in enrolling participants into CoVPN 3502-01 also highlights the importance of timely enrollment to minimize recall bias.

Project description:IntroductionEstablishing a positive body image is a critical factor for adolescents' physical and mental health, as it determines self-confidence, and sustainable individual growth and development throughout their lives. This reality needs to be supported by evidences generated locally. However, there is a lack of information in this regard in the study setting. Thus, the aim of this study was to assess the self-perception of one's physical appearance and its associated factors among adolescents in Addis Ababa, Ethiopia.Methods and materialsA community-based, cross-sectional study design was used to conduct the study. At the end of the multistage sampling procedure, a systematic random sampling technique was employed to select 308 study participants from selected districts. The questionnaire was adapted from previous studies as it was appropriate for local context. The data collectors were trained before the data collection and supervised during the data collection period, and the questionnaire was pretested. Bivariate logistic regression was used to identify candidate variables, and then variables with p<0.2 were taken to multiple logistic regressions to identify independent associated factors. Statistical significance was considered at P <0.05 with adjusted odds ratios calculated at 95% CIs.ResultA total of 283 adolescents were participated in the study, with a response rate of 91.9%. The overall good self-perception of one's physical appearance was 48.4% [95% CI = 43.8, 54.1]. Having a BMI between 18.5 kg/m2-24.9 kg/m2 (AOR = 2.56; 95% CI: 1.45, 4.54), presence of enough sport fields in the school (AOR = 1.89; 95% CI: 1.09, 3.29), having daily access to internet services (AOR = 1.69; 95% CI: 1.07, 2.94), following Ethiopian movies/cinemas (AOR = 2.46; 95% CI: 1.46, 4.15), and regularly following western movies/cinemas (AOR = 2.0; 95% CI: 1.11, 3.59) were significantly associated with a good self-perception of one's physical appearance.ConclusionAccording to this study, only 48.4% of respondents reported a good self-perception of their physical appearance. Adolescents and their family need to work to bring normal body mass index, which in turn will increase good self-perceptions of their physical appearance. Schools and the local administrations need to increase availability and access to enough sport fields for students to strengthen their physical fitness, which increases their good self-perception of their physical appearance.
