OBJECTIVESSubstance abuse behaviors among university freshmen in Iran are poorly understood. This study aimed to identify, for the first time, subgroups of university freshmen in Iran on the basis of substance abuse behaviors. Moreover, it examined the effects of socio-demographic characteristics on membership in each specific subgroup.METHODSData for the study were collected cross-sectionally in December 2013 and January 2014 from 4 major cities in Iran: Tabriz, Qazvin, Karaj, and Khoramabad. A total of 5,252 first-semester freshmen were randomly selected using a proportional cluster sampling methodology. A survey questionnaire was used to collect data. Latent class analysis (LCA) was performed to identify subgroups of students on the basis of substance abuse behaviors and to examine the effects of students’ socio-demographic characteristics on membership in each specific subgroup.RESULTSThe LCA procedure identified 3 latent classes: the healthy group; the hookah experimenter group; and the unhealthy group. Approximately 82.8, 16.1, and 2.1% of students were classified into the healthy, hookah experimenter, and unhealthy groups, respectively. Older age, being male, and having a family member or a close friend who smoked increased the risk of membership in classes 2 and 3, compared to class 1.CONCLUSIONSApproximately 2.1% of freshmen exhibited unhealthy substance abuse behaviors. In addition, we found that older age, being male, and having a close friend or family member who smoked may serve as risk factors for substance abuse behaviors.
Background: There is a very limited information on the obscenity of cigarette and hookah smoking among adolescents. Using a large and representative longitudinal sample of adolescents ( n = 4820) aged 14–19 years from Tabriz (a metropolitan city in northwestern Iran), this study aimed at comparing the obscenity of cigarette and hookah smoking and assessing factors associated with obscenity of smoking. Moreover, we examined how the obscenity of cigarette and hookah smoking affected by the progress in the stages of cigarette and hookah smoking. Methods: In this longitudinal study, a random sample of high-school students was selected in Tabriz in 2010. Using a valid and reliable self-administered questionnaire, the data from the sampled students were collected twice at two points in time, 12 months apart. Multivariate backward logistic regression was used to determine the effect of the transition in cigarette (or hookah) smoking stages on the obscenity of cigarette (or hookah) smoking. Results: While 3,079 (63.9%) students expressed that obscenity of cigarette smoking is higher than obscenity of hookah smoking, 1,741 (36.1%) students expressed that obscenity of hookah smoking is higher than obscenity of cigarette smoking. The results of multivariate backward logistic regression indicated that the transition in cigarette (hookah) smoking stages was not related to the obscenity of cigarette (hookah) smoking. Conclusions: The results showed that obscenity of hookah smoking was less than obscenity of cigarette smoking, especially among females. Further study is required to understand the effect of obscenity on smoking and transition to different stages of cigarette and hookah smoking.
Both exaggerated and blunted cardiovascular stress reactions are associated with health problems. Moreover, early life experiences and personality traits affect stress responses. Regarding the childhood traumas and type D personality, this study aimed to compare the endocrine and cardiovascular reactions against acute laboratory stress. Results showed that the simultaneous existence of childhood traumatic experiences and type D personality leads to exaggerated stress reactivity, while each factor results in a blunted cardiovascular response. Although the cardiovascular responses are dampened in type D personality people, their endocrine reactions are exaggerated. The underlying mechanisms of blunted cardiovascular reactivity differ between childhood trauma and type D personality groups.
The present study aimed to determine the roles of maternal care and overprotection. We also explored how they are combined to develop rumination as well as various childhood traumas and parenting styles as the risk factors for depression. Methods: This was a retrospective study with a causal-comparative design. In total, 175 students with the ِ Mean±SD age of 21±2.75 years (age range: 18-35 years) affiliated to Alborz Medical University, Tehran University, and Kharazmi University have been selected using purposive sampling method. They completed the 2nd version of Beck Depression Inventory, Ruminative Response Scale, Parental Bonding Instrument, and Childhood Trauma Questionnaire. The obtained data were analyzed by the Analysis of Variance (ANOVA), path analysis, mediation analysis, and correlation calculations, in SPSS and AMOS. Results: The mediating role of rumination in respect of parenting styles (P<0.02) and depression (P<0.001) was statistically significant. Moreover, parenting styles and childhood traumas, and their interaction may lead to the development of rumination and depression (P<0.001). The pathways of the effects were different; limited maternal care plays an indirect role in this process. This indicates that it will lead to depression and rumination only if emotional abuse is experienced in childhood. However, overprotection can directly lead to these conditions. Conclusion: Paying attention to parenting styles, childhood traumas, and their interaction to prevent rumination and depression is important. This is due to the identified direct and indirect effects of parenting behaviors.
ObjectivesThe aim of this study is to investigate the mediating role of rumination in relation to the attachment styles and depression symptoms. Methods This is an expost facto study with causal design. Around 175 students of Iranian University answered to Beck Depression Inventory-II (BDI-II), Ruminative Responses Scale (RRS), and the Adult Attachment Questionnaire (AAQ), which were analyzed using variance analysis, regression, and mediation analysis. Results The study results showed that attachment orientation is related to rumination (P<0.001) and depression (P<0.0005). Specifically, avoidance index of attachment system is strongly associated with brooding (P<0.002). Our results also supported the mediating role of brooding in between avoidance index and depression symptoms (P<0.0005). Conclusion Brooding mediate in between avoidance index and depression symptoms. The study findings also emphasize the role of caregiver-child relationship in the formation of rumination and depression, and recommend implementing preventive programs in order to restrain the development of such dysfunctional construct.
