A szerzők célja, hogy két esetük kapcsán felhívják a figyelmet a polycystás ovarium szindróma, illetve hyperandrogenismus és a petefészekciszta-torzió közötti összefüggésre peripubertális korú leányoknál. Praemenarche-korban, illetve fiatal serdülőkben az androgéntúlsúllyal járó polycystás ovarium szindróma gyakrabban okozhat petefészekciszta-képződést, mint felnőttkorban. A szerzők javasolják, hogy peripubertás korú serdülőknél petefészekciszta-torzió esetén ki kell zárni a polycystás ovarium szindróma és késői típusú congenitalis adrenalis hyperplasia lehetőségét. Polycystás ovarium szindróma igazolása esetén a beteg korának és a pubertás fejlődésének megfelelő kezelést el kell kezdeni. Orv. Hetil., 2013, 154, 113–117.

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 (M age = 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.
