To investigate the structural relationships between chronic pain and body mass index mediated by eating behaviors, pain-related fear, anxiety sensitivity, and pain catastrophizing.

The research method was structural equation modeling and the statistical population of men and women with chronic pain referred to the orthopedic, physiotherapy, neurology wards of Al-Ghadir Hospital and orthopedic specialists of Farahbakhsh clinics in Tehran in spring, summer and autumn of 2022, of which 400 they were selected by purposive sampling method and participated in the research. Data were used to calculate participants' body mass index and the Dutch Eating Behavior Questionnaire (Van Strien, Frijters, Bergers & Defares, 1986), Chronic Pain (Vankorff et al, 1990), Pain Anxiety Symptom Scale (Pain-Related Fear) (McCracken & Dhingra, 2002), Anxiety Sensitivity Questionnaire (Patterson and Reese, 1992) and Pain Catastrophic Scale (Sullivan, Bishop, & Pivik, 1995) were collected and analyzed using structural equation modeling in Amos21 software.

The results showed that the model has a good fit with the observed data (df2c <3, GFI, AGFI and CFI> 0.90 and RMSEA <0.08). Chronic pain, pain-related fear, anxiety sensitivity, catastrophic pain, and eating behaviors can explain 29.6% of the variance in body mass index. 55.2% of the variance of eating behaviors is explained by chronic pain, pain-related fear, anxiety sensitivity, and catastrophic pain.

To prevent and treat obesity in people with pain, the variables of pain-related fear, anxiety sensitivity, catastrophic pain and eating behaviors should be targeted.

The purpose of the present study is to examine the mediating role of anxiety sensitivity and pain-related fear in the relationship between pain catastrophizing and emotional eating in people with chronic pain. The research method is descriptive-correlational. The statistical population includes patients with chronic pain who were treated in Tehran clinics in districts 4 and 8 in the spring, summer, and fall of 2019. 300 of them were selected by purposive sampling. Body mass index calculation and questionnaires Dutch Eating Behavior Questionnaire (DEBQ), Anxiety Sensitivity Index (ASI), Pain Anxiety Symptoms (PAS) and Pain Catastrophizing Scales (PCS) were used to collect data. Data were analyzed using structural equation modeling in Amos 21 software. Results confirmed the mediating role of anxiety sensitivity (P = 0.05, t = 1.954, β = 0.137) and anxiety related to pain (P = 0.001, t = 3.244, β = 0.106) in the association between pain catastrophizing and emotional eating. 46.3% of the variance in emotional eating can be explained by pain catastrophizing, anxiety sensitivity, and pain-related anxiety. It seems that to prevent and treat emotional eating in people with pain and to maintain the therapeutic effect, pain-related cognitive and emotional structures such as anxiety sensitivity and pain-related anxiety should be targeted for therapeutic intervention.

To investigate the mediating role of eating behaviors in the relationship between chronic pain and pain catastrophizing with body mass index in people with chronic pain.

The research method was correlation. The sample (n = 400) were recruited through purposive sampling method from patients (males and females) with chronic pain who were visiting orthopedic, physiotherapy, neurology wards of Al-Ghadir Hospital and Farahbakhsh Clinic in Tehran in spring, summer and autumn of 2016. Participants' body mass index were collected, as well as, participants' responses on the Dutch Eating Behavior Questionnaire (VanStrien, Frijters, Bergers & Defares, 1986), Chronic Pain Questionnaire (VonKorff, Dworkin & Le Resche, 1990), and the Pain Catastrophizing Scale (Sullivan, Bishop & Pivik, 1995), then analyzed using structural equation modeling employing Amos software.

The results showed that the model has a good fit (df2 <3, GFI, AGFI and CFI> 0.90 and RMSEA <0.08). Examination of the path coefficients showed that pain (β = 0.303, P = 0.001; β = 0.148, P = 0.001) and pain catastrophizing (β = -0.149, P = 0.001; β = 0.153, P = 0.001) have a significant direct and indirect effect on body mass index, respectively. Furthermore, chronic pain, pain catastrophizing, and eating behaviors explained for 30.5% of the variance in body mass index.

The interaction between pain experience and pain catastrophizing with eating behaviors affects body mass index.

The aim of the present study was to investigate the efficacy of BATD on the treatment of obese women with depression and anxiety. In this study, 45 obese women (45 patients with a BMI equal to or greater than kg/m2 30) suffering from depression and anxiety were divided randomly into three groups of fifteen. All members of these groups were matched in terms of age, sex, education level and BMI. Research tools of this study included Beck Depression Inventory, Spielberger State-trait Anxiety Inventory,and treatment package of BATD. After taking a pre-test, the experiment group underwent 10 sessions of BATD, the regimen group received the treatment concerning the reduction of weight, and the third group received no treatment. After the termination of these interventions, the subjects took a post-test. The results of the multivariate analysis showed that behavioral activation treatment for depression(BATD) was effective in reducing the anxiety and depression symptoms of the patients with obesity. One of the probable reasons for the effectiveness of BATD, the increase of the level of pleasant, important activities and the promising events in the patient’s life can be mentioned. Finally, the results of this study are consistent with the results of other research.

The main aim of the current study was to investigate the performance of the obese individuals comparing with the normal subjects and those who recovered by diet regime on the executive function. Three groups of women subjects from Tehran city including obesity group (N= 30, BMI ≥30 kg/m2), recovered obesity group (N=30, has reduced their weight by diet), and normal control group (N=30, without any history of obesity and psychological problems) who were matched by age and level of education were participated at this study. The instruments were included Wisconsin Cart Sorting Test (WCST), Stroop task, Beck Depression Inventory (BDI) and State – Trait Anxiety Inventory. The results showed that obese group and recovered group performed worse than normal group on Wisconsin Cart Sorting Test (WCST) and Stroop task. The results are consisting with the previous findings and also indicated that the obese patients suffer from cognitive problems.
