The COVID-19 pandemic restrictions may have significant implications for patients with multiple sclerosis (MS). The objective of this study is to explore the impact of the pandemic on physical activity levels and health outcomes among MS patients, as well as to examine potential associations between these factors. In this cross-sectional study, 197 patients with confirmed MS diagnosis were included. Physical activity and health status were assessed using international physical activity questionnaire-long form (IPAQ-LF) and short form 36 health survey questionnaire (SF-36) during the period of restrictions. The relationship between clinical characteristics, physical activity levels and health status parameters were examined. A total of 45 participants (22.8%) scored low, 73 (37.1%) scored moderate, and 79 (49.1%) achieved a high level of physical activity during the COVID-19 pandemic. We observed no significant association between total physical activity and any domains of SF-36 health status, except for pain. However, correlations were found between IPAQ and SF-36 domains. Specifically, walking showed positive correlations with physical functioning, physical limitation, general health, and physical component summary score. Vigorous activity demonstrated a negative correlation with social functioning, while moderate activity displayed a positive correlation with energy levels. Despite the challenges of home isolation and quarantine, most of our participants managed to achieve a moderate to high level of physical activity, while their overall health status was found to be moderate. Additionally, significant correlations were identified between the domains of health status and different types of physical activity, particularly walking. Further studies are warranted to optimize the care and support provided to patients with MS.

Diabetes mellitus (DM) and its related complications such as diabetic retinopathy (DR) are among considerably growing global concerns. Many efforts have been done toward a better understanding of the modifiable risk factors of DR, to stop progression as well as prevention of this complication. Physical activity (PA) is a known modifiable risk factor of DM but its effect on the severity of DR is not clearly understood. In this study, we aimed to evaluate the association between PA and severity of DR.

 A case-control study was done comprising 232 patients with DM (type 1 or 2), 58 of whom were in control group with no sign of DR, while the others were divided into three subgroups each contained 58 individuals, according to the severity of DR. PA of patients was assessed by the International Physical Activity Questionnaire (IPAQ) short-version and total scores of PA were compared among different groups.

  Total PA scores in (metabolic equivalent [MET]-hour/week) in control group, in patients with mild to moderate non-proliferative diabetic retinopathy (NPDR), severe to very severe NPDR, and proliferative diabetic retinopathy were 24.6 ±28.3, 23.7 ±30.6, 17.1 ± 27.0, and 7.1 ±10.2, respectively. The lower the score of PA, the higher the stage of DR (r=-0.284, p<0.001). Low PA levels came with higher stages of DR (odds ratio [OR]=2.7, P=0.023) than moderate PA (OR=2.1, P=0.114). When adjusted for age, sex, duration of DM, and type of medication regimen, the association of DR severity with PA level was still statistically significant in mild PA group (P=0.049) and statistically insignificant in moderate PA group (P=0.132). Adjusting for hemoglobin A1c (HbA1c) and body mass index (BMI) showed no significant correlation between PA level and DR severity (OR=1.1 and P=0.794 in low PA group, OR=1.2 and P=0.670 in moderate PA group).

 Low PA level can be identified as a risk factor for DR, but not a completely independent one. It is more likely that PA lowers the risk of DR progression through lowering BMI and achieving better glycemic control (HbA1c).

Physical activity (PA) is one of the prime public health problems occurring globally. Regular PA is associated with a decrease in all‑causes of mortality irrespective of gender. The study was conducted to investigate the validity and an aspect of reliability of a modified version of the International Physical Activity Questionnaire (IPAQ) in the Indian subcontinent (InS).

Cross‑sectional study, to evaluate the validity and reliability of the InS IPAQ‑LF compared with a range of biological variables. In total, 198 participants (50% women) with a mean age of 35.6 (SD = 10.3) years selected from neighborhoods with variable socioeconomic status and PA.

The InS IPAQ‑LF demonstrated good test‑retest reliability for total PA (Intraclass correlation coefficient [ICC] =0.79, 95% CI 0.65 to 0.82), occupational PA (ICC = 0.77, 95% CI 0.68 to 0.82), active transportation (ICC = 0.82, 95% CI 0.75 to 0.87), and vigorous‑intensity activities (ICC = 0.82, 95% CI 0.76 to 0.87). Reliability was substantially higher for total PA (ICC = 0.80), occupational PA (ICC = 0.78), leisure‑time PA (ICC = 0.75), and active transportation (ICC = 0.80) in men than in women, but domestic PA (ICC = 0.38) and sitting time (ICC = 0.71) demonstrated more substantial reliability coefficients in women than in men.

The InS IPAQ‑LF demonstrated considerate evidence of test‑retest reliability and may be valid for evaluating context specific PA mannerisms of adults in InS.

In large populations, the level of cardiorespiratory fitness (CRF) can be evaluated by estimating non-exercise models with the least amount of time and money. In this study, we present non-exercise equations for predicting CRF and also investigate the effect of socio-environmental factors on it.

2490 male and female subjects aged 25-65 years old from different cities of Iran participated in this study. Rockport and Bruce (10% in each age category and gender) exercise test measured VO2max, a global standard for evaluation of CRF. Three non-exercise equations including, VO2masStep, VO2maxIPAQ-s, and VO2maxIPAQ-l were estimated using Stepwise Linear Regression. Variables for estimating these models are physical activity (PA) (obtained by pedometer and short and long-form of the International Physical Activity Questionnaire (IPAQ), separately), Body Mass Index (BMI) , Waist-Hip Ratio(WHR), Body Adiposity Index (BAI ), age, gender, and VO2maxROC. For comparison between measured and predicted VO2max values based on age, gender, level of education and city of residence Repeated Measures Analysis with Bonferroni Compare Main Effect test was used.

There were significant relationships between measured and estimated VO2max (p<0.05) (VO2maxIPAQ-l: R2adj=0.671 and SEE=4.381, VO2maxStep: R2adj=0.543 and SEE=5.331 and VO2maxIPAQ-s: R2adj=0.621 and SEE=4.823). Also, there were significant differences between VO2max values in males and females in different age categories and city of residence (p<0.05).

The results of this study demonstrated that predicted VO2max models with SC, IPAQ-s, and IPAQ-l can be used as non-exercise models for estimating VO2max in Iranian society, and socio-environmental factors are influential variables on PA and level of CRF.

Physical activity (PA) is protective against non‑communicable diseases and it can reduce premature mortality. However, it is difficult to assess the frequency, duration, type and intensity of PA. The global physical activity questionnaire (GPAQ) has been developed by World Health Organization with the aim ofhaving valid and reliable estimates of PA. The primary aim of this study is to assess the repeatability of the GPAQ instrument and the secondary aim is to validate it against International Physical Activity Questionnaire (IPAQ) and against an objective measureof PA (i.e., using pedometers) in both rural and peri‑urban areas of North India. A total of 262 subjects were recruited by random selection from Ballabgarh Block of Haryana State in India. For test retest repeatability of GPAQ and IPAQ, the instruments were administered on two occasions separated by at least 3 days. For concurrent validity, both questionnaires were administered in random order and for criterion validity step counters were used. Spearman’s correlation coefficient, intra‑class correlation (ICC) and Cohen’s kappa was used in the analysis. For GPAQ validity, the spearman’s Rho ranged from 0.40 to 0.59 and ICC ranged from 0.43 to 0.81 while for IPAQ validity, spearman correlation coefficient ranged from 0.42 to 0.43 and ICC ranged from 0.56 to 0.68. The observed concurrentvalidity coefficients suggested that both the questionnaires had reasonable agreement (Spearman Rho of >0.90; P < 0.0001; ICC: 0.76‑0.91, P < 0.05). GPAQ is similar to IPAQ in measuring PA and can be used for measurement of PA in community settings.
