Background:The prevalence of overweight and obesity is on the increase the world over, which imposes an ever-increasing burden on societies and health care systems.Objectives:This study sought to investigate the effect of motivational interviewing (MI) on a weight-loss program based on the protection motivation theory (PMT).Patients and Methods:This randomized clinical trial study, comprising pretest-posttest with a control group, was conducted on 150 overweight and obese women attending a private nutrition clinic for the first time. Samples were randomly selected using the clinic’s records and then allocated to three groups (50 women in each group) receiving: 1) a standard weight-control program; 2) motivational interviewing; and 3) MI plus intention intervention. Data were collected using a researcher-made questionnaire through in-person interviews and were analyzed using SPSS (version 11) and statistical tests, including the Kruskal-Wallis test, one-way analysis of variance, paired t-test, and linear regression model.Results:In the two intervention groups, the PMT construct scores, namely susceptibility (P = 0.001), severity (P = 0.001), rewards (P =0.004), self-efficacy (P = 0.001), response efficacy (P = 0.001), and costs (P = 0.014), were significantly increased compared to those in the control group. The anthropometric status was statistically significant in the MI group (P = 0.001) and the MI plus intention-intervention group (P = 0.001) at 2 months’ follow-up, while in the control group, weight was meaningfully different after the intervention (P = 0.027). Weight was different between the groups after the intervention, with the Tukey test demonstrating that the differences were statistically significant between the control group and the MI group.Conclusions:Our results demonstrated that MI, combined with the implementation of intention intervention, increased weight loss and PMT construct scores in our study population.
OBJECTIVESWe aimed to investigate factors associated with colorectal cancer survival in Golestan, Iran.METHODSWe used a population based cancer registry to recruit study subjects. All patients registered since 2004 were contacted and data were collected using structured questionnaires and trained interviewers. All the existing evidences to determine the stage of the cancer were also collected. The time from first diagnosis to death was compared in patients according to their stage of cancer using the Kaplan-Meir method. A Cox proportional hazard model was built to examine their survival experience by taking into account other covariates.RESULTSOut of a total of 345 subjects, 227 were traced. Median age of the subjects was 54 and more than 42% were under 50 years old. We found 132 deaths among these patients, 5 of which were non-colorectal related deaths. The median survival time for the entire cohort was 3.56 years. A borderline significant difference in survival experience was detected for ethnicity (log rank test, p=0.053). Using Cox proportional hazard modeling, only cancer stage remained significantly associated with time of death in the final model.CONCLUSIONSColorectal cancer occurs at a younger age among people living in Golestan province. A very young age at presentation and what appears to be a high proportion of patients presenting with late stage in this area suggest this population might benefit substantially from early diagnoses by introducing age adapted screening programs.
Background: Ovarian cancer (OC) has high incidence and mortality rates among the reproductive system cancers. This study investigated the relationship between the agestandardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of OC and Human Development Index (HDI) in European countries in 2012.

Modification de l'attitude et de l'intention vis-à-vis d'une activité physique régulière à l'aide de la théorie de la motivation à la protection : essai contrôlé randomisé RÉSUMÉ Nous nous sommes servis de la théorie à la motivation à la protection pour tester l'impact des entretiens motivationnels sur l'attitude et l'intention des femmes obèses et en surcharge pondérale vis-à-vis de la pratique d'une activité physique régulière. Lors d'un essai contrôlé randomisé, 60 femmes obèses et en surcharge pondérale se présentant dans des centres de santé ont été sélectionnées par échantillonnage de commodité. Les femmes ont été réparties en deux groupes, chaque groupe comprenant 30 femmes suivant un programme standard de gestion du poids ou assistant à des entretiens motivationnels. Les composantes de la théorie (vulnérabilité perçue, gravité, auto-efficacité et efficacité de la réponse) ainsi que les caractéristiques anthropométriques (sauf l'indice de masse corporelle) étaient toutes significativement différentes entre les groupes à trois moments de l'étude. Les indicateurs de l'intention les plus forts concernant la pratique régulière de l'exercice physique étaient l'efficacité de réponse perçue et l'attitude lors du suivi à deux et six mois. Nous avons prouvé que la réalisation des entretiens motivationnels en mettant l'accent sur la théorie de la motivation à la protection s'est avérée profitable pour la conception et l'élaboration des interventions appropriées afin d'améliorer le statut de l'activité physique chez les femmes obèses et en surcharge pondérale. ABSTRACT We were guided by the Protection Motivation Theory to test the motivational interviewing effects on attitude and intention of obese and overweight women to do regular physical activity. In a randomized controlled trial, we selected using convenience sampling 60 overweight and obese women attending health centres. The women were allocated to 2 groups of 30 receiving a standard weight-control programme or motivational interviewing. All constructs of the theory (perceived susceptibility, severity, self-efficacy and response efficacy) and all anthropometric characteristics (except body mass index) were significantly different between the groups at 3 study times. The strongest predictors of intention to do regular physical exercise were perceived response efficacy and attitude at 2-and 6-months follow-up. We showed that targeting motivational interviewing with an emphasis on Protection Motivation Theory constructs appeared to be beneficial for designing and developing appropriate intervention to improve physical activity status among women with overweight and obesity. شواهد ذات معشاة جتربة
