Limited energy intake with physical activity is effective to reduce health problems associated with obesity. It has been shown that PYY3-36 level increased after intense exercise. This study investigated effect of exercise therapy on appetite suppression and weight loss among obese and/or overweight women.

There was a quasi-experimental with a pretest-posttest design, two groups (control-exercise) study. Study population was overweight or obese women with 20-34 years old and body mass index 27-34 kg/m2. 13 women were randomly assigned in 2 groups (exercise group with 8 weeks of aerobic exercise training (n=7) and control group (n=6)). Weight, waist circumference, hip circumference, lipid profile, cortisol and PYY3-36 were measured at baseline and end of the study.

In baseline of study, there was no significant difference across the groups in factors mean (P>0.05).In control group, after 8 weeks, there was no significant difference in variables.(P>0.05) However, In exercise group significant decrease was observed in BMI, WHR, PYY3-36, TG, CHOLESTROL(TC) and LDL, compared to control group (P<0.05).

Aerobic exercise within the 80% of heart rate reserve is beneficial in lipid profile, appetite management and modified anthropometric factors. These studies demonstrate that a cortisol change is not along with PYY3-36 changes. We suggest the longer exercise training for this purpose.

Vitamin D is one of the known lipoprotein hormones with metabolic properties. We aimed to determine the serum 25-hydroxy vitamin D concentration in overweight/obese subjects with diabetes mellitus type Ⅱ (DM Ⅱ) in association with systolic and diastolic blood pressure and quality of life compared with healthy participants.

The current case-control study was carried out among 80 overweight/obese subjects with DM Ⅱ, and 77 healthy subjects matched by sex, age and body mass index (BMI). Serum 25-hydroxyvitamin D concentration was measured by ELISA method. In order to examine the quality of life, the Persian version of SF36 questionnaire was used.                   

There was significant difference between diabetic and healthy subjects considering serum 25-hydroxyvitamin D concentration (p-value = 0.012). Serum 25-hydroxyvitamin D concentration was inversely correlated with diastolic blood pressure (p-value = 0.02) and positively associated with physical function (p-value <0.001), social function (p-value <0.001) and general health (p-value <0.001) components of quality of life in diabetic subjects and physical health sub-scale (p-value = 0.004) in all participants.

Serum 25-hydroxyvitamin D concentration was significantly lower in diabetic subjects in comparison with healthy controls. There was a significant reverse relationship between serum concentrations of 25-hydroxyvitamin D with diastolic blood pressure and on the other hand, a significant positive relationship with physical function, social function and general health components and physical health subscale of quality of life in participants with DM Ⅱ.

 Women are vulnerable and face variety of problems during pregnancy that can affect mental health and life quality. Pregnancy complications make pregnant women more prone to loss of quality of life and mental health problems. The purpose of this study was to investigate the effect of probiotic supplement on quality of life and depression in women with gestational diabetes mellitus (GDM).

In this double blind randomized clinical trial, performed on pregnant women with GDM referring to the specialized centers of gynecology and endocrinology in Tabriz, 64 pregnant women with GDM in 24-28 weeks of pregnancy were randomly assigned to receive either probiotic supplementation or placebo for 8 weeks. Probiotic supplement was a combination of four strains of Lactobacillus acidophilus, Bifidobacterium, Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. The short form of Iranian species of World Health Organization Quality of Life Questionnaire was used to assess the quality of life and the Edinburgh Depression Inventory to assess depression before and after intervention.

Fifty six surveyed individuals completed the study. The effect of probiotic supplementation on changes in the physical dimension of quality of life was significant, with statistically remarkable increase of 2.59 ± 2.19 units in the probiotic group compared with 2.25 ± 0.88 decrease in the placebo group (p = 0.045). Also, the increase in mean of total quality of life in the probiotic group was 5.17 ± 1.46 units which was significant compared with 0.46 ± 1.61 units increase in the placebo group (p = 0.029). The effect of probiotic supplementation in comparison with placebo was significant in improving depression (p = 0.042).

It seems that probiotic supplementation promotes quality of life and depression levels in pregnant women with GDM.

Vitamin D deficiency is one of the most important health problems of any society. It is more common in elderly even in those dwelling in rest homes. By now, several studies have been conducted on vitamin D deficiency using current statistical models. In this study, corresponding proportional odds and stereotype regression methods were used to identify threatening factors related to vitamin D deficiency in elderly living in rest homes and comparing them with those who live out of the mentioned places.

In this case-control study, there were 140 older persons living in rest homes and 140 ones not dwelling in these centers. In the present study, 25(OH)D serum level variable and age, sex, body mass index, duration of exposure to sunlight variables were regarded as response and predictive variables to vitamin D deficiency, respectively. The analyses were carried out using corresponding proportional odds and stereotype regression methods and estimating parameters of these two models. Deviation statistics (AIC) was used to evaluate and compare the mentioned methods. Stata.9.1 software was elected to conduct the analyses.

Average serum level of 25(OH)D was 16.10±16.65 ng/ml and 39.62±24.78 ng/ml in individuals living in rest homes and those not living there, respectively (P=0.001). Prevalence of vitamin D deficiency (less than 20 ng/ml) was observed in 75% of members of the group consisting of those living in rest homes and 23.78% of members of another group. Using corresponding proportional odds and stereotype regression methods, age, sex, body mass index, duration of exposure to sunlight variables and whether they are member of rest home were fitted. In both models, variables of group and duration of exposure to sunlight were regarded as meaningful (P<0.001). Stereotype regression model included group variable (odd ratio for a group suffering from severe vitamin D deficiency was 42.85, 95%CI:9.93-185.67) and duration of exposure to sunlight variable (odd ratio for a group suffering from severe vitamin D deficiency was 0.717, 95%CI: 0.642-0.792).

This study demonstrated high prevalence of vitamin D deficiency in older people living in rest homes comparing with those who do not live in such centers. It seems that stereotype regression as a modern method among multicategory logistic models is well capable in sieving kinds of diseases especially vitamin D deficiency.
