Abstract Background Obesity is well known as a risk factor for cardiovascular disease. We aimed to determine the performance of and the optimal cutoff values for obesity indices to discriminate the presence of metabolic abnormalities as a primary risk factor for cardiovascular diseases in a Health Examinees study (HEXA). Methods The current study analyzed 134,195 participants with complete anthropometric and laboratory information in a Health Examinees study, consisting of the Korean population aged 40 to 69 years. The presence of metabolic abnormality was defined as having at least one of the following: hypertension, hyperglycemia, or dyslipidemia. The area under the receiver operating characteristic curve (AUC) and 95% confidence intervals (CIs) were calculated for body mass index, waist to hip ratio, waist to height ratio, waist circumference, and conicity index. Results The AUC of metabolic abnormalities was the highest for waist-to-height ratio (AUC [95% CIs], 0.677 [0.672–0.683] among men; 0.691 [0.687–0.694] among women), and the lowest for the C index (0.616 [0.611–0.622] among men; 0.645 [0.641–0.649] among women) among both men and women. The optimal cutoff values were 24.3 kg/m2 for the body mass index, 0.887 for the waist-to-hip ratio, 0.499 for the waist-to-height ratio, 84.4 cm for waist circumference and 1.20 m3/2/kg1/2 for the conicity index among men, and 23.4 kg/m2 for the body mass index, 0.832 for the waist-to-hip ratio, 0.496 for the waist-to-height ratio, 77.0 cm for the waist circumference and 1.18 m3/2/kg1/2 for the conicity index among women. Conclusion The waist-to-height ratio is the best index to discriminate metabolic abnormalities among middle-aged Koreans. The optimal cutoff of obesity indices is lower than the international guidelines for obesity. It would be appropriate to use the indices for abdominal obesity rather than general obesity and to consider a lower level of body mass index and waist circumference than the current guidelines to determine obesity-related health problems in Koreans.

Sexual violence is a major public health, societal, and judicial problem worldwide. Studies investigating the characteristics of its offenders often rely on samples of convicted offenders, which are then biased by low reporting and conviction rates of sexual offences. The reliability of self-report studies of undetected sexual offenders, however, is threatened by underreporting of sexually aggressive acts. Despite these limitations, we argue that it is important to publish available data on self-disclosed sexual aggression to learn more about those who are more likely to report own sexual aggression and to further improve self-report methods. Based on a self-report study conducted in a representative sample (n = 4,693) of the Belgian general population aged 16 to 69, we provide lifetime and past-year prevalence rates of sexual aggression and report the characteristics of the events, including type, target, and the applied coercion strategies. A logistic regression analysis revealed factors associated with self-disclosed sexual aggression. Almost 4% of all participants reported at least one incident of hands-on sexual aggression. Men were more likely than women to report sexual aggression (aOR: 5.33 (95% CI:3.62-7.86). Furthermore, a history of sexual victimization was associated with sexual aggression. In most cases, the target was an (ex)partner or friend. About 4 in 5 perpetrators indicated that none of the given coercion strategies (i.e., force, threat, verbal pressure, or exploiting the victim’s incapacitation or the own position of authority) applied to the incident. Further research is needed to clarify under which circumstances sexual aggression occurs and which factors increase reporting thereof.

Abstract Background and aims Previous studies on smartphone use motivation (SUM) and problematic smartphone use (PSU) have been limited in the utilization of regional samples of emerging adults (e.g., college students) and also in the foci on the direct association between SUM and PSU. To address such gaps, using data from a large, national representative sample of Chinese young adolescents and their parents this study examined the associations between adolescents' various types of SUM and their PSU, and also tested the potential mediating roles of smartphone use time (SUT) that adolescents spent on various activities in such associations. Methods A nationwide representative sample of 8,261 Chinese adolescents (Mage = 12.86 years old, SD = 1.76; 42.6% females) and their parents (49% mothers) participated in this survey study. Results Instrumental SUM (i.e., to expand knowledge or acquire information) was associated negatively with PSU via longer SUT spent on learning and shorter SUT spent on entertainment and communication. Self-expression SUM (i.e., to gain acceptance and recognition of others by maintaining or improving self-images) was associated with longer SUT spent on both learning and entertainment, which, in turn, predicted lower and higher levels of PSU, respectively. Last, hedonic SUM (i.e., to gain pleasure) was associated positively with PSU via longer SUT spent on entertainment and communication. Discussion These findings contribute to the literature by adding greater specificity in our understanding of the implications of SUM and SUT in the etiology of PSU during the critical life stage of adolescence in a Chinese cultural context.
