ABSTRACT
OBJECTIVE: Attention deficit hyperactivity disorder in adults (adult ADHD) is gaining more attention nowadays. Nevertheless, very few studies have addressed this issue in Iran. The present study was conducted to determine the prevalence of adult ADHD in Tabriz, North-West of Iran. METHODS: Four hundred urban inhabitants of Tabriz- with an age range of 18 to 45 years were selected through the probability proportional to size cluster sampling in 2009. The screening was performed by Conner's Adult ADHD Rating Scale, and the definite diagnosis of Adult ADHD was performed via clinical interview according to DSM-IV-TR and Wender Utah criteria. RESULTS: The prevalence of adult ADHD was estimated to be 3.8%. Men when compared with women were more likely to have ADHD (5.5 % in men versus 2 % in women). Marital status, birth order, educational level and occupational status showed no significant association with adult ADHD. History of psychiatric treatment, alcohol drinking and smoking had similar relative frequency in subjects with and without adult ADHD. CONCLUSION: The prevalence of adult ADHD in this region of Iran seems to be substantially higher than expected or treated. This would require more attention to be drawn by health sector managers in order to improve the knowledge of the general population and the knowledge of the health care professionals about the disorder.
ABSTRACT
To date a few studies have focused on the possible effects of subclinical hyperthyroidism on bone metabolism, showing conflicting results. This study was designed to evaluate this possibility. Sixty-six patients, 22 pre-menopausal women, 33 post-menopausal women and 11 men, who had received iodine-131 ((131)I) ablation postoperatively for well differentiated thyroid carcinoma (WDTC) and were treated for a long term with levothyroxine (T(4)), entered the study and were compared with sixty-six healthy controls individually matched to the patients for age, gender and menopausal status. The bone mineral density (BMD) of lumbar and hip regions of the patients was measured, while on the T(4) suppressive treatment, with average duration of 14.93+/-2.17 months after initiation of the T(4) suppressive treatment and was compared with the BMD of healthy controls. All patients were in the subclinical hyperthyroid state, while all controls were serologically and clinically euthyroid. Our results show that there was no significant difference in BMD measured at the lumbar spine of patients and controls in any subgroup (P>0.05). Analysis of the data of BMD from the hips in men, premenopausal women and controls, also revealed no difference. It was noted that the mean BMD of the femur in the postmenopausal women were at the statistical limit of significance as compared to the control group (P=0.05). In conclusion, our findings indicate that the replacement dose of T(4) in WDTC patients after (131)I ablation, does not have a significant effect on BMD in men, in pre and post-menopausal women and hence on the risk of osteoporosis. In post-menopausal women, the mean femoral BMD was at the limit of statistical significance.
