- Normal subjects (n = 64) were exposed either to pictures of snakes and spiders or to pictures of flowers and mushrooms in a differential conditioning paradigm in which one of the pictures signaled an electric shock. In a subsequent extinction series, these stimuli were presented backwardly masked by another stimulus for half of the subjects, whereas the other half received non-masked extinction. In support of a hypothesis that suggests that nonconscious information-processing mechanims are sufficient to activate responses to fear-relevant stimuli, differential skin conductance response to masked conditioning and control stimuli was obvious only for subjects conditioned to fear-relevant stimuli. These results were replicated in a second experiment (n = 32), which also demonstrated that the effect was unaffected by which visual half-field was used for stimulus presentation.

Determinants of social inequalities in cardiovascular disease among Iranian patients
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and objectives: Cardiovascular disease (CVD) is the single largest cause of mortality in the world. Similar to other health issues, CVD is generally affected either by individual risk factors, which may influence the risk for developing an illness or its complications, or by social indicators (social determinants of health). There is evidence from developed countries which shows that the so-called "upstream factors"—including social determinants such as political, social, spiritual, cultural, and economic factors—may affect the prevalence and incidence of CVD. Scarce evidence from studies in low- and middle-income countries also suggests that social factors may affect the distribution of CVD across population groups. However, there is a dearth of such data in Iran, where only a few small-sizedstudies have focused on the social determinants of health. Therefore, the present thesis sought to fill this gap by assessing the effects of socioeconomic status (SES) on the distribution of CVD and the relevant inequalities within the Iranian context.Methods: This thesis is based on four studies, which used data from the Tehran Heart Center’s Databases. In Study I, a total of 44,820 patients who underwent coronary angiography at Tehran Heart Center between 2005 and 2010 were recruited. Then, their pre- and post-procedural data—including demographics, CVD risk factors, symptoms, and laboratory tests—were compared between men and women. In Study II, 6,246 patients with acutecoronary syndrome who were hospitalized between March 2004 and August 2011 were included and, based on their education and their employment status, were divided into high- and low-SES groups. Thereafter, the effect of SES on the in-hospital death of the patients was evaluated. In Study III, 20,165 patients with documented coronary artery disease who underwent coronary angiography at Tehran Heart Center were enrolled and CVD risk factors and severity (measured by the Gensini score) were assessed among the six major Iranian ethnic groups. In Study IV, 9,088 patients with acute coronary syndrome who were hospitalized at Tehran Heart Center between May 2007and June 2014 were recruited and the association between in-hospital death due to acute coronary syndrome and place of residence (rural/urban) was assessed using logistic regression adjusted for potential confounders.Results: In this thesis, the data analyses were based on the hypothesis that there is a potential association between the different socioeconomic indicators and the selected cardiovascular outcomes. In Study I, among the recruited participant, 25,363 men and 11,995 women had coronary artery disease and the women not only were significantly older, less educated, and more overweight but also had higher blood levels of triglyceride, cholesterol, low-density lipoprotein, high-density lipoprotein, and fasting blood sugar than the men. Moreover, hypertension and diabetes mellitus showed the strongest association in the women with coronary artery disease (OR=3.45, 95% CI: 3.28to 3.61 and OR=2.37, 95% CI: 2.26 to 2.48, respectively). In addition, the frequency of post-procedural recommendations for non-invasive procedures was higher in the women than in the men (20.1% vs 18.6%; P<0.001). In StudyII, of the 6,246 recruited patients with acute coronary syndrome, 3,290individuals were considered low-SES and 2,956 high-SES individuals. In-hospital death occurred in 79 (1.26%) patients: 1.9% in the low-SES and 0.6% in the high-SES groups. After adjustment for the possible cofounders, our multivariate analysis demonstrated a significant effect of the patients’ SES on their in-hospital death and a lower in-hospital mortality rate was shown in the high-SES patients (OR=0.30, 95% CI: 0.09 to 0.98; P=0.046). In Study III, the Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest frequency of having at least four simultaneous risk factors. Additionally, the mean Gensini score was lowest in the Lurs (67.5±52.8) and highest among the Gilaks (77.1±55.9). The multivariable regression analysis indicated that the Gilaks showed the worst CVD severity (β: 0.056, 95% CI: 0.009 to 0.102; P=0.018), followed by the Turks (β: 0.032, 95% CI: 0.005 to 0.059; P=0.020), and the lowest CVD severity, was detected in the Lurs (β: -0.087, 95% CI: -0.146 to -0.027;P=0.004). Study IV showed that while smoking (P=0.002), positive family history of coronary artery disease (P=0.003), higher body mass index (P=0.013),and hyperlipidemia (P=0.026) were more prevalent in the urban patients, the rural patients showed lower educational levels (P<0.001) and higher frequency of unemployment (P=0.009). Meanwhile, in-hospital death occurred in 135 (1.5%) patients: 125 (1.5%) urban and 10 (1.2%) rural. To adjust the effects of the possible confounders, we utilized the Firth regression model, which showed no significant difference regarding in-hospital death betweenthe rural and urban patients (OR=1.57, 95% CI: 0.376 to 7.450; P=0.585).Conclusions: The aim of this thesis was to investigate the effects of social determinants (particularly SES) on CVD and its modifiable risk factors among Iranian patients. Results showed that medical treatment for CVD was more recommended (by treating physicians) to the women than the men, and the low-SES patients with acute coronary syndrome were more likely to die in the hospital than their high-SES counterparts. In addition, the thesis found heterogeneity in the distribution of the traditional risk factors for CVD as well as CVD severity in the major Iranian ethnic groups. Further, there were no differences concerning the in-hospital death rates due to acute coronary syndrome between the urban and rural patients after adjustment for the potential confounders.

- Background Diverse ethnic groups may differ regarding the risk factors and severity of coronary artery disease (CAD). This study sought to assess the association between ethnicity and CAD risk and severity in six major Iranian ethnic groups.Methods In this study, 20,165 documented coronary artery disease patients who underwent coronary angiography at a tertiary referral heart center were recruited. The demographic, laboratory, clinical, and risk factor data of all the patients were retrieved. The Gensini score (an indicator of CAD severity) was calculated for all, and the risk factors and severity of CAD were compared between the ethnical groups, using adjusted standardized residuals, Kruskal–Wallis test, and multivariable regression analysis.Results The mean age of the participants (14,131 [70.1%] men and 6034 [29.9%] women) was 60.7 ± 10.8 years. The Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest prevalence of ≥4 simultaneous risk factors. The mean Gensini score was the highest for the Gilaks (77.1 ± 55.9) and the lowest among the Lors (67.5 ± 52.8). The multivariable regression analysis showed that the Gilaks had the worst severity (β 0.056, 95% CI 0.009 to 0.102; P = 0.018), followed by the Torks (β 0.032, 95% CI 0.005 to 0.059; P = 0.020). Meanwhile, the Lors showed the lowest severity (β −0.087, 95% CI −0.146 to −0.027; P = 0.004).Conclusions This study found that there was heterogeneity in CAD severity and a diverse distribution in its well-known traditional risk factors among major Iranian ethnic groups.

- Background: Current evidence shows inequality in the outcomes of rural and urban patients treated at their place of residence. This study compared in-hospital mortality between rural and urban patients with acute coronary syndrome (ACS) to find whether there were differences in the outcome and received treatment.Methods: Between May 2007 and January 2018, patients admitted with ACS were included. The patients’ demographic, clinical, and laboratory data, as well as their in-hospital medical courses, were recorded. The association between place of residence (rural/urban) and in-hospital mortality due to ACS was evaluated using logistic regression adjusted for potential confounders.Results: Of 9088 recruited patients (mean age =61.30±12.25 y; 5557 men [61.1%]), 838 were rural residents. A positive family history of coronary artery disease (P=0.003), smoking (P=0.002), and hyperlipidemia (P=0.026), as well as a higher body mass index (P=0.013), was seen more frequently in the urban patients, while the rural patients had lower education levels (P<0.001) and higher unemployment rates (P=0.009). In-hospital mortality occurred in 135 patients (1.5%): 10 rural (1.2%) and 125 urban (1.5%) patients (P=0.465). The Firth regression model, used to adjust the effects of possible confounders, showed no significant difference concerning in-hospital mortality between the rural and urban patients (OR, 1.57; 95% CI, 0.376 to 7.450; P=0.585).Conclusion: This study found no significant differences in receiving proper treatment and in-hospital mortality between rural and urban patients with ACS.

- Objective: The aim of this study was to estimate the prevalence of elder abuse and neglect in Iran.Methods: We searched PubMed, Embase, Scopus, and PsycINFO by the end of 2017. The prevalence was calculated based on the percentage or the amount reported in the studies. Heterogeneity was assessed by the I2 statistic, and the data were combined using random effects model. The results were reported as the pooled estimates and the 95% confidence intervals (CIs). The review protocol was registered in PROSPERO (CRD42017070744).Results: A total of 16 studies involving 6,461 participants aged 60 years and over were included. The pooled prevalence for overall elder abuse was 45.7% (95% CI: 27.3–64.1, p < .001).Discussion: The prevalence of elder abuse and neglect is substantial in the Iranian population aged 60 years and over. More research is needed to investigate the actual prevalence of elder abuse at the national level.

- Background: Suicide is a leading cause of death worldwide and becoming a public health concern among adolescents. However, adolescent suicidal behaviour is a neglected public health issue, especially in low-income countries such as Bangladesh. Of great importance is the understanding of which factors might be related to this growing public problem. Objective: To examine the relationship between parental socio-economic position and suicide ideation among adolescents in rural Bangladesh Methods: A cross-sectional survey was conducted in 2013 among 2,476 adolescents, aged 14-19 years, selected randomly from a rural community of Bangladesh. An adapted version of the WHO/SUPRE-MISS questionnaire was used to collect data in the Raiganj sub-district, which is a surveillance area of the Centre for Injury Prevention and Research, Bangladesh (CIPRB).Descriptive statistics and binary logistic regression analyses were used to analyze the data. Comparisons of proportions between groups were carried out using the χ2 test. Multivariate logistic regression analysis was used to examine the relationship between parental co-variants and suicidal thoughts among adolescents. The significance level was set atp <0.05. All analyses were performed using SPSS 20. Results: The majority of parents had education only up to primary school (mothers 58.7% and fathers 49.5%). Most of them were farmers (53.3% of fathers) and housewives (96.5% of mothers). Monthly income and expenditure of the adolescent’s parents were mainly upto 10,000 taka only. Suicidal ideation is more common among adolescents of low income group parents 104 (5.5%) and who were not living with their parents 18 (8.2%). Adolescent’s suicidal ideation was found to be significantly associated with education, marital status and house ownership of their parents. Not being able to live with their parents was also a significant factor. Parents who received education up to SSC had odds ratio of 2.10 (1.21,3.64) and 1.92 (1.15, 3.23) for mothers and fathers respectively. Parent’s income or expenditure was not associated with adolescent’s suicidal ideation. Adolescent’s suicidal ideation of single parents had higher odds (OR 3.00, CI 1.75-5.19) in comparison to adolescents who had both parents. Adolescents whose parents owned a house and who weren’t living withtheir parents had odds ratios of 0.14 (0.05,0.35), and 1.80 (1.07,3.03) respectively. After adjusting for other covariates parents’ marital status and house ownership significantly associated with the adolescent suicide ideation. Conclusion: Parental socio-economic position was associated with suicidal ideation. Adolescent with single parents were more likely to report suicidal ideation. Low parental education and socio-economic status, marital status, house ownership, not living with parents at home as well as adolescent loneliness were the important factors for suicidal ideation.

- Suicide is a leading cause of death world-wide. However, adolescent suicidal behavior is a neglected public health issue, especially in low-income countries such as Bangladesh. The study was conducted to estimate the prevalence of suicidal ideation among adolescents in a rural community and to examine factors associated with suicidal ideation. A cross-sectional survey was carried out in 2013 among 2,476 adolescents aged 14–19 years, selected randomly from a rural community of Bangladesh. An adapted version of the WHO/SUPRE-MISS questionnaire was used to collect data in the Raiganj sub-district. A two stage screening was performed to identify the suicidal ideation cases. It was found that the life-time prevalence for suicidal ideation was 5 percent among adolescents. The majority of the adolescents with suicidal ideation were females 66 (52.8%), unmarried 103 (82.4%), and students 92 (73%). Suicidal ideation was statistically significantly associated with age, education, occupation, living with parents or others, and house ownership. Respondents who were aged 18–19 years, had secondary school certificate (SSC) and secondary school certificate (HSC) or higher education, were day laborers, had own house, and do not lived with parents had odds ratios of 2.31 (CI 1.46–3.65), 2.38 (CI 1.51–3.77), 4.15 (CI 2.41–7.14), 0.28 (CI 0.13–0.60), 0.14(CI 0.05–0.35), and 1.80 (CI 1.07–3.03), respectively. Among adolescents, the prevalence of life-time suicidal ideation was moderately high. Age, education, occupation, house ownership, and living with parents were statistically significantly associated with suicidal ideation. It is important to design and implement effective community based suicide prevention programs for adolescents in Bangladesh.

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and Objective: Suicide is a leading cause of death and a critical public health problem among adolescents worldwide. However, adolescent suicidal behaviour is a neglected public health issue, especially in low- and middle-income countries, such as Bangladesh. There is evidence from developed countries showing that suicidal ideation (SI) among adolescents is related to social indicators as well as individual risk factors. Scarce evidence from studies inlow- and middle-income countries suggests that social factors may influence adolescent SI. In Bangladesh, only a few studies have focused on the social determinants of suicide, and the present study is the first to examine the prevalence and social determinants of suicidal ideation among adolescents in rural Bangladesh. Therefore, the present thesis assessed the effects of socioeconomic status (SES) on adolescent SI.Methods: The present thesis is based on two studies, which used data from a cross-sectional survey conducted in 2013 among 2,476 adolescents aged 14-19 years selected randomly in arural community in Bangladesh. An adapted version of the WHO/SUPRE-MISS questionnaire was used to collect data in the Raiganj sub-district, an area surveyed within the Injury Prevention Program of the Centre for Injury Prevention and Research, Bangladesh (CIPRB). Study I estimated the prevalence of suicidal ideation among adolescents and investigated what factors were associated with suicidal ideation. Study II examined the relationship between parental socio-economic factors and suicidal thoughts among adolescents.Results: Study I showed that life time prevalence of suicidal ideation was 5% among adolescents. The majority of adolescents with suicidal ideation were female (67, 5.3%), unmarried (106, 5.5%) and students (86, 6.2%). Suicidal ideation was significantly associated with age, education, occupation and living with parents or others. Respondents aged 18-19 years, had a Secondary school certificate (SSC) and Higher Secondary school certificate (HSC) or higher, were day labourers, living without parent had odds ratios of 2.31 (CI 1.46-3.65), 2.38(CI 1.51-3.77), 4.15 (CI 2.41-7.14), .28 (CI 0.13-0.60) and 1.80 (CI 1.07-3.03), respectively.In study 2, results demonstrated that suicidal ideation was more common among adolescents with parents from the low-income group (5.5%). In addition, adolescent SI was found to be significantly associated with parental education, marital status and house ownership. Adolescents whose parents received an SSC or higher had an SI odds ratio of 2.10 (CI 1.21-3.64) and 1.92 (CI 1.15-3.23) for mothers and fathers respectively. Suicidal ideation among adolescents with single parents was higher with an odds ratio of 3.00 (CI 1.75-5.19) in comparison to adolescents who had both parents. Adolescents whose parents owned a house had an odds ratio of 0.14 (0.05, 0.35).Conclusion: The thesis found that the prevalence of lifetime suicidal ideation among adolescents is moderately high in a rural community of Bangladesh. Furthermore, it was observed that personal characteristics such as parental marital status, education and homeownership were statistically significantly associated with suicidal ideation among adolescentseven after adjusting for potential confounders.

- The aim was to estimate the prevalence of sexual and physical intimate partner violence (IPV) and its associated factors, in a sample of pregnant women using antenatal care (ANC) in Nampula province - Mozambique. This cross-sectional study was carried out in six health units in Nampula, from February 2013 to January 2014. Overall, 869 participants answered the Conflict Tactics Scale 2. The lifetime and past year prevalence of sexual abuse was 49% and 46%, and of physical abuse was 46% and 44%, respectively. Lifetime and past year sexual abuse was significantly associated with living as a couple, alcohol drinking and having a past diagnosis of gonorrhea. Lifetime and past year physical abuse increased significantly with age and was associated with living as a couple, alcohol drinking and history with syphilis. The prevalence of lifetime and previous year violence among women using ANC was high and similar showing that most women were constantly exposed to IPV. ANC provides a window of opportunity for identifying and acting on violence against women.
