Socioeconomic Disparities in Iranians' Preferences toward Dental Care Services: A Population-Based Survey.

Background and Aims: Patients' perspectives and preferences are considered an essential influencing factor for healthcare utilization. This study is one of the first to investigate patient preference for dental services across socioeconomic and demographic indicators in Iran. Materials and Methods: This cross-sectional study was conducted through telephone interviews with adult residents in Mashhad and Kerman cities. A representative sample was selected by stratified random sampling. A valid structured questionnaire was used for data collection, including people's preference toward dental care services in terms of dental settings, choosing a general or specialist dentist, prevention or treatment, and the preferable gender of the dentist. Factors potentially associated with preferences included gender, age, educational level, job, monthly income, house size, family number, insurance coverage, dental insurance, type of insurance, and social class in the city were investigated. Results: 1475 individuals participated in the study [response rate 63%]. Our findings showed higher preferences for private offices (50.6%), specialist dentists (76.2%), treatment services (40.8%), and no specific gender preference for the dentist (60.6%). Their preferences were significantly influenced by age range, social class, insurance status, dental insurance, and type of insurance. Income, household size, level of education, and job were not statistically significant with none of the preferences. Conclusions: Socioeconomic and demographic factors' correlation with people's preferences was observed. Efforts are needed to promote preventive care demand in deprived regions. Moreover, increasing financial resources allocated to preventive care and covering preventive dental services in insurance plans are recommended.

Developed and validated food frequency questionnaires in Iran: A systematic literature review.

BACKGROUND: Food frequency questionnaires (FFQs) are inexpensive, easy to administer, and practical tools for dietary assessment in epidemiological studies. Several studies have investigated the validity and reproducibility of FFQs for the Iranian population. This systematic review aimed to assess the developed and validated FFQs for use in the Iranian population and compare their features and the validation studies in this regard. MATERIALS AND METHODS: A comprehensive search was conducted in ISI Web of Knowledge, PubMed, Scopus, and Iranian databases without time constraints to retrieve the relevant English and non-English publications. Studies would be included if they were focused on the design and validation of FFQs in Iran. RESULTS: In total, 782 articles were found, 22 of which met the eligibility criteria and evaluated 18 FFQs. Validation studies had been conducted on 18 out of 20 FFQs. The median of the correlation coefficients for the comparison of the FFQ intakes and the dietary reference method by nutrients varied within the range of 0.19-0.65, indicating reasonable validity. The median of the correlation coefficients for the comparison of two FFQs by nutrients was 0.28-0.85, showing appropriate reproducibility. However, low validity was observed in some nutrients and food groups, such as egg, legumes, iron, folate, and α-tocopherol. In seven studies, biomarkers were used for the assessment of nutrient intake using an FFQ with the median correlation coefficient of -0.07-0.42. In addition, the quality of methodology was evaluated in the FFQ validation studies, with 18 out of 20 studies reporting good and excellent quality. CONCLUSION: Although the FFQs used to assess the dietary intake of the Iranian population have different features, they have acceptable validity and reproducibility. Nevertheless, some food groups and nutrients have poor validity and must be considered attentively.

Inequalities in Unmet Oral Health Care Need Among Adults in East Iran, a Cross Sectional Population-Based Study.

STATEMENT OF THE PROBLEM: Need assessment is considered as a key element of health care planning. Subjective measures can be useful tools in epidemiologic surveillances. PURPOSE: The aim of study was to evaluate inequality in perceived unmet oral health need (PUOHN) in adults in east of Iran. MATERIALS AND METHOD: In this cross-sectional population-based study, the target population included adult residents in the Mashhad and Kerman city. Data was collected through telephone interviews using a validated structured questionnaire. Phone numbers were obtained from telecommunication company. Participants were selected by stratified random sampling. Predisposing and enabling variables associated with PUOHN were included gender, age, educational level, job, insurance coverage, dental insurance, type of insurance, residential location, household size, and family economic indicators. Logistic regression was used to examine association of PUOHN and predisposing and enabling factors. RESULTS: 1475 individuals participated in the study (response rate of 63%). 52% of participants stated that their dental needs have not been met during the past year. The mean ages of respondents were 39 years old and 69.8% were female. Logistic regression analyses indicated living in rental house [OR=2 (95% CI 1.25-3.21), p Value=0.004] and higher household size [OR=1.19(95% CI 1.003-1.43), p= 0.04] significantly associated with PUOHN. CONCLUSION: The results of this study indicated high PUOHN in the adult population of East Iran. Effective strategies must be implemented to provide accessible dental services regardless of socioeconomic status.

The Effect of Cognitive Rehabilitation on Balance Skills of Individuals with Multiple Sclerosis.

Balance skills can be affected by slow information processing speed in people with multiple sclerosis. This study explored the effect of cognitive-based rehabilitation on balance skills of individuals with multiple sclerosis. Seventy-one participants with multiple sclerosis were randomly assigned to the usual occupational therapy exercises as a control group (n = 36, male = 10) or the cognitive rehabilitation group (n = 35, male = 10). Using several assessments pre-intervention, post-intervention and two months after completion, participants in the cognitive rehabilitation group showed significant improvement in their balance skills in post-test and as well as follow-up measurements compared to the control group. Results also showed a large effect of cognitive rehabilitation for balance (eta-squared= 0.59) and for information processing speed measured. Inclusion of tasks related to information processing speed to the usual occupational therapy exercises seemed to be able to improve the balance skills of people with multiple sclerosis.

Intrarater reliability of musculoskeletal ultrasound imaging of psoas major muscle in patients with subacute low back pain and healthy controls.

Background: Psoas major (PM) is a challenging muscle from the functional and anatomical point of view. The dysfunction of this muscle can result in low back pain (LBP). This study aimed to assess the intrarater reliability of ultrasound imaging (USI) of PM muscle thickness in subacute LBP patients and healthy participants without LBP in rest and during muscle contraction conditions. Methods: PM thickness was measured in all lumbar segments (L1-L5) using a USI device in 10 healthy and 10 subacute LBP participants. The intrarater data were assessed on the same day with 1- hour interval and after 7 days. Intraclass correlation coefficients (ICC), standard error of measurement (SEM), minimal detectable change (MDC), and independent t test were used for analyses. Significant level was set at 0.05. Results: PM thickness in all lumbar levels had excellent reliability (ICC range 80-98) for both groups and conditions. SEM (0.42- 2.29) and MDC (1.16-6.34) were low, and PM thickness was greater than rest in contraction condition. There were no significant differences between the 2 groups in PM thickness. Conclusion: The USI demonstrated good intrarater reliability for assessing PM thickness in patients with subacute LBP. The thickness of PM in patients with subacute LBP was similar with that in healthy participants.

The effect of upper trapezius muscle dry needling treatment on sleep quality: A case report.

Myofascial pain syndrome is characterized by trigger points in muscles, resulting in pain, limitation of motion, muscle weakness and also referral pain. Upper part of trapezius muscle is one the most common sites in upper quadrant affected by this condition. Among various manual and non-manual techniques, dry needling is one of the most effective treatment methods, and is widely used recently by physiotherapists. A 34 year old, female hairstylist with chronic shoulder pain was admitted to a physiotherapy clinic and was treated with dry needling approach, after which she found improvement of shoulder symptoms and sleep quality. Results from this case report can create an interesting and clear precedent for considering dry needling treatment in future clinical trials.
