Development and psychometric testing of a new instrument to measure factors influencing women’s breast cancer prevention behaviors (ASSISTS)

BackgroundBreast cancer preventive behaviors have an extreme effect on women’s health. Despite the benefits of preventive behaviors regarding breast cancer, they have not been implemented as routine care for healthy women. To assess this health issue, a reliable and valid scale is needed. The aim of the present study is to develop and examine the psychometric properties of a new scale, called the ASSISTS, in order to identify factors that affect women’s breast cancer prevention behaviors.MethodsA multi-phase instrument development method was performed to develop the questionnaire from February 2012 to September 2014. The item pool was generated based on secondary analyses of previous qualitative data. Then, content and face validity were applied to provide a pre-final version of the scale. The scale validation was conducted with a sample of women recruited from health centers affiliated with Tehran University of Medical Sciences. The construct validity (both exploratory and confirmatory), convergent validity, discriminate validity, internal consistency reliability and test-retest analysis of the questionnaire were tested.ResultsFifty-eight items were initially extracted from the secondary analysis of previous qualitative data. After content validity, this was reduced to 49 items. The exploratory factor analysis revealed seven factors (Attitude, supportive systems, self-efficacy, information seeking, stress management, stimulant and self-care) containing 33 items that jointly accounted for 60.62xa0% of the observed variance. The confirmatory factor analysis showed a model with appropriate fitness for the data. The Cronbach’s alpha coefficient for the subscales ranged from 0.68 to 0.85, and the Intraclass Correlation Coefficient (ICC) ranged from 0.71 to 0.98; which is well above the acceptable thresholds.ConclusionThe findings showed that the designed questionnaire was a valid and reliable instrument for assessing factors affecting women’s breast cancer prevention behaviors that can be used both in practice and in future studies.

Metabolic Syndrome is Associated with Health-Related Quality of Life in Suspected Patients with Nonalcoholic Steatohepatitis

Objective: This study was designed to examine the effect of metabolic syndrome (MetS) on health-related quality of life (HRQOL) in patients with suspected nonalcoholic steatohepatitis (NASH). Subjects and Methods: Three hundred thirty-two patients (236 males and 96 females) with suspected NASH from the Amol cohort study were included in this study. MetS was diagnosed based on Adult Treatment Panel III criteria and HRQOL was measured using the 12-Item Short-Form Health Survey (SF-12) questionnaire (with 8 subscales and 2 summary components). A multivariable linear regression model was used to assess the independent effect of MetS on HRQOL. Results: The mean age of the study population was 42 ± 13 years (range 18–82). The prevalence of MetS was 43.4% (n = 144) and the mean scores on the Physical Component Summary (PCS) and the Mental Component Summary were 72.4 ± 20.86 and 42.7 ± 12.42, respectively. The multivariable linear regression model showed that MetS was negatively associated with 4 subscales of HRQOL that included: role limitations due to physical problems (RP) (B = –14.05, p = 0.004), bodily pain (BP) (B = –7.37, p = 0.02), vitality (VT) (B = –7.72, p = 0.022), and role limitations due to emotional problems (RE) (B = –12.67, p = 0.005) after adjustment for other variables. Also, MetS had a borderline association with the general health and mental health subscales and the PCS (p < 0.1). Conclusion: In this study, there was a strong association between MetS and 4 subscales (RP, BP, VT, and RE) of HRQOL in patients with suspected NASH; this could be considered as a part of health policy to improve general health.

Association between Nicotinamide Phosphoribosyltransferase and de novo Lipogenesis in Nonalcoholic Fatty Liver Disease

Objective: This study explored the association between serum nicotinamide phosphoribosyltransferase (NAMPT) and hepatic de novo lipogenesis (DNL) in nonalcoholic fatty liver disease (NAFLD) and determined whether or not this association is sex dependent. Subjects and Methods: In this cross-sectional study, 62 consecutive patients (32 males, 30 females) with NAFLD were recruited. Serum NAMPT (by ELISA), palmitic acid, and the DNL index of erythrocyte membranes as markers of hepatic DNL (by gas chromatography) were analyzed. The controlled attenuation parameter (CAP) and body impedance analyzer were used to assess hepatic and body fat, respectively. Univariate and multiple linear regressions (to adjust for confounders) were used to analyze the association of serum NAMPT with palmitic acid, DNL index, CAP, and body fat. Results: The respective values of serum NAMPT (2.44 ± 1.03 vs. 2.45 ± 1.13 ng/mL, p = 0.98), DNL index (3.11 [2.60-3.71] vs. 3.05 [2.40-3.59], p = 0.90), and palmitic acid (20.55% [15.34-24.04] vs. 22.64% [21.15-25.95], p = 0.07) were not significantly different between men and women, but those of CAP (326 [300-340] vs. 300 [261.25-329], p = 0.002) and body fat (37.71 ± 3.80 vs. 26.60 ± 5.70, p < 0.001) were significantly higher in women. In women, serum NAMPT had a significant negative association with the DNL index (β = -0.56, p = 0.01). The DNL index also had a significant negative association with body fat (β = -0.46, p = 0.02). In men, the only significant association was the positive association between serum NAMPT and CAP (β = 0.35, p = 0.035). Conclusion: Higher serum NAMPT in women was associated with a lower hepatic DNL index, while in men it was associated with higher hepatic fat and had no association with the DNL index. Therefore, the serum NAMPT level interpretation for NAFLD prognosis is probably sex dependent.

Association between Pattern of Gastritis and Gastroesophageal Reflux Disease in Patients with Helicobacter Pylori Infection

BACKGROUND Reflux disease is a common gastrointestinal problem. The association between reflux disease and gastritis pattern is controversial. AIM: To determine the association between reflux disease and gastritis pattern in patients with Helicobacter pylori (H. pylori) infection. METHODS 470 patients with dyspepsia and reflux disease were enrolled in this study. The inclusion criteria were willing to participate in the study, age over 40 years, and having the criteria of ROME III for at least 3 months. Patients with history of H. pylori eradication therapy during the 3 months before the study, a history of gastric surgery, and gastric cancer were excluded. All of the participants underwent upper endoscopy and two biopsy samples were taken from antrum, body, and fundal areas. RESULTS H. pylori infection rate was 367 (78.1%) with mean age of 59.8 ± 11.4 years. Of them 131 patients (35.7%) were male. Reflux disease was detected in 273 (74.4%) patients. 216 (58.9%) and 102 (27.8%) patients had non-erosive reflux disease (NERD) and gastroesophageal reflux disease (GERD), respectively. Corpus predominant and antral predominant gastritis were seen in 72 (19.6%) and 129 (35.2%) patients, respectively. Antral gastritis was significantly associated with GERD (p<0.01). In regression analysis, antral predominant gastritis had a significant association with GERD (OR=1.92; 95%CI: 1.22- 3.12). The same result was observed in mild to moderate antral and greater curvature gastritis (OR= 1.26; 95%CI: 0.25-6.40 and OR= 3.0; 95%CI: 0.63-14.17, respectively). CONCLUSION According to these finding ,we could suggest that the pattern of gastritis could be associated with reflux disease and GERD.

Non-medical factors affecting antenatal preferences for delivery route and actual delivery mode of women in southwestern Iran

Abstract Objective: Assessment of the contribution of non-medical factors to mode of delivery and birth preference in Iranian pregnant women in southwestern Iran. Study design: This cohort study used data from a structured questionnaire completed in early pregnancy and information about the subsequent delivery obtained through personal contact. Women were recruited by random sampling from antenatal clinics when scheduling visits over the course of 5 weeks from December 2012 to February 2013 and were followed-up 1 month after birth. Of the 2199 women recruited, 99.63% were eligible for the study. Results: Of the 748 women who expressed a desire to deliver their babies by cesarean section (CS) in early pregnancy, 87% had an elective cesarean section. The logistic regression analyses showed that normative beliefs (odds ratio [OR] 1.792, 95% confidence interval (1) 1.073–2.993), control beliefs (OR: 0.272, 95% CI: 0.162–0.459), and evaluation of outcomes (OR: 0.431, 95% CI: 0.268–0.692) favored the preference for cesarean section. The desire for delivery by elective cesarean section was associated with normative beliefs (OR: 1.138; 95% CI: 1.001–1.294), control beliefs (OR: 0.804; 95% CI: 0.698–0.927), and expectations about maternity care (OR: 0.772; 95% CI: 0.683–0.873), medical influences (OR: 1.150; 95% CI: 1.023–1.291), evaluation of outcome (OR: 0.789; 95% CI: 0.696–0.894), age, preference for cesarean section (OR: 5.445; 95% CI: 3.928–7.546), spouse educational level, and number of live births. Conclusions: A woman’s preference for delivery by cesarean section influenced their subsequent mode of delivery. Asking women in early pregnancy about their preferred mode of delivery provides the opportunity to extend their supports which might reduce the rate of elective cesarean section. This decision is affected by age, spouse educational level, number of live births, and preconceived maternal attitudes about delivery.

Application of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) to patients with cataract

OBJECTIVES: Cataract is a prevalent disease in the elderly, and negatively influences patients’ quality of life. This study was conducted to study the application of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) to patients with cataract. METHODS: In this cross-sectional study, 300 patients with cataract were studied in Neyshabur, Iran from July to October 2014. The Iranian version of the WHOQOL-BREF questionnaire was used to measure their quality of life. Cronbach’s alpha coefficient, Pearson’s correlation coefficient, the paired t-test, the independent t-test, and a linear regression model were used to analyze the data in SPSS version 16.0 (SPSS Inc., Chicago, IL, USA). RESULTS: The mean age of the participants was 68.11±11.98 years, and most were female (53%). The overall observed Cronbach’s alpha coefficient for the WHOQOL-BREF was 0.889, ranging from 0.714 to 0.810 in its four domains. The total mean score of the respondents on the WHOQOL-BREF was 13.19. The highest and lowest mean scores were observed in the social relationship domain (14.11) and the physical health domain (12.29), respectively. A backward multiple linear regression model found that duration of disease and marital status were associated with total WHOQOL scores, while age, duration of disease, marital status, and income level were associated with domains one through four, respectively (p<0.05). CONCLUSIONS: The reliability analysis conducted in this study indicated that the WHOQOL-BREF scale exhibited an acceptable degree of internal consistency in the measurement of the quality of life of patients with cataract. It was also found that the patients with cataract who were surveyed reported a relatively moderate quality of life.

Cigarette smoking patterns in relation to religiosity andfamilial support among Iranian university students:A Latent Class Analysis

INTRODUCTION Entering University is an important developmental milestone that might be associated with cigarette smoking. The aim of this study was to identify the subgroups of university students on the basis of cigarette smoking patterns, and to assess the role of familial support and religious beliefs on membership in specific subgroups. METHODS This cross-sectional study was performed in 2016 using multistage random sampling among students of Bushehr University (n=977). Anonymous, structured questionnaires were distributed to the students in each selected class. Cigarette smoking prevalence was assessed in three time intervals: lifetime, last year, and last month. All of the analyses were performed using PROC LCA in the SAS software. RESULTS The lifetime, last-year and last-month prevalence of cigarette smoking was 13.7%, 10.0% and 7.0%, respectively. In this study, the prevalence of passive smoking was relatively high (15.3%) among students. Four latent classes were identified: 1) non-smoker 58.2%, 2) passive smoker 31.3%, 3) moderate smoker 3.4%, and 4) heavy smoker 7.1%. The prevalence of cigarette smoking of close friends was: 73% among passive smokers, 81% for heavy smokers and 63% for moderate smokers. Being male (OR=4.42, 95% CI; 2.90–6.74) and a higher score of religious beliefs (OR=0.97, p<0.001 95% CI; 0.96–0.98) were associated with the heavy smoker class. CONCLUSIONS Among students at Bushehr University in Iran, 10.5% were either moderate or heavy smokers in 2016. These results point out the critical importance of designing specific preventive interventional programs for university students. Higher level of religiosity may serve as a preventive factor in engaging in cigarette smoking.

Physical activities (exercises or choreses) during pregnancy and mode of delivery in nulliparous women: A prospective cohort study

OBJECTIVEnThe aim of this study was to investigate changes in physical activities during pregnancy and the relationship between physical activity and unplanned caesarean sections (CSs).nnnMATERIALS AND METHODSnA cohort study design was carried out. A cohort of 2029 pregnant women was established when they received prenatal care at 18-22 weeks of gestation in a medical center in southwest Iran. Participants were asked to recall their levels of physical activity during pre-pregnancy. The data were processed using Statistics/Data Analysis. To compare activities the chi-square was used to identify significant differences between the groups. A multiple logistic regressian was used to identify the association between activities and delivery mode as well as controlling potential confounding variables. In the analyses, the level of significance was set at Pxa0<xa00.05.nnnRESULTSnIn total, 2029 pregnant women participated in the study, among which 1334 (65.84%) underwent CSs and 692 (34.16%) underwent NVDs. The study indicated the odds ratio of CS was 0.68 (95% CI: 0.47-0.97) for a pregnant woman who increased her level of activity during pregnancy compared to pre-pregnancy.nnnCONCLUSIONnThe results of this study showed that regular and standard physical activities during pregnancy can reduce the risk of caesarean section in pregnant women. These findings can be important in convincing health care providers to prescribe regular and standard physical activities for pregnant women during pregnancy.

Is household food insecurity a determinant of weight status in patients with type 2 diabetes in rural areas

Background: There is mixed evidence about food insecurity and overweight/obesity coexisting, however it is unclear about association between food insecurity and weight status in people with type 2 diabetes. Therefore, the aim of this study was to evaluate the relationship between food insecurity and weight status in individuals with type 2 diabetes in rural areas in Iran. Methods: 1847 patients with type 2 diabetes who were residence in rural areas completed Household Food Security Scale (six-item short questionnaire). Logistic regression model was applied to assess the independent effect of food insecurity on weight status. Results: Mean age of the study population was 62.6±11.8 years, and the majority of them were female (70.4%). Most of the study population (70.4%) had unhealthy weight status. Food insecurity affected more than 46% (n=852) of the households of the study population. According to weight status, more than 40% (n=565) of overweight and obese subjects and 60% (n=18) of underweight subjects lived in households with food insecurity. The results of multiple logistic regression model showed that food insecurity was not an independent significant predictor of overweight or obesity in patients with type 2 diabetes. However, low food security (LFS) was an independent significant predictor for underweight in patients with type 2 diabetes (OR=2.35, P=0.041). Conclusion: It is concluded that food insecurity was frequent in all levels of weight status of patients with type 2 diabetes in rural regions. However this association observed in underweight individuals but there was no significant overall relationship between household food insecurity and in overweight and obesity in this group of patients.

Exploring breast cancer preventive lifestyle and social support of Iranian women: a study protocol for a mixed-methods approach

BackgroundIt is widely accepted that a healthy lifestyle may decrease the probability of developing cancer. This study aimed to describe a study protocol that makes it possible to explore preventive health lifestyles of Iranian women and their received social support for the purpose of developing cultural strategies to increase breast cancer prevention.MethodsA mixed-methods study will be accomplished in two sequential parts. First, a cross-sectional study will be conducted in which 2,250 Iranian women are recruited by using a random multistage cluster sampling of 20 health care centers. Structured face-to-face interviews will be conducted to obtain information on the participants’ health lifestyle and perceived social support. Data will be analyzed using both multivariate regression and structural equation modeling techniques. Then, a qualitative study will be conducted among employed women using a purposive sampling design. Data will be collected by means of focus groups and semi-structured interviews and will be analyzed using a conventional content analysis approach. The results of the quantitative and qualitative study will be used to develop breast cancer preventive strategies.DiscussionResearchers need to acquire knowledge regarding the lifestyle and perceived social support of Iranian women that will foster culturally competent approaches to promote healthy lifestyles to develop breast cancer preventive strategies. Examining breast cancer preventive lifestyles provides valuable information for designing applicable intervention programs for improving women’s health.
