Dietary glycaemic load and odds of depression in a group of institutionalized elderly people without antidepressant treatment

Background

Depression is a very common disorder in elderly, especially in those institutionalized. Nutrition could play an important role in the onset and/or progression of depression, since the intake of carbohydrates with a high glycaemic index (GI) or diets with a high glycaemic load (GL) may increase the insulin-induced brain serotonin secretion.

Objective

The aim of our study was to analyse the association between dietary GI and GL and the odds of suffering depression in institutionalized elderly people without antidepressant treatment.

Methods

This cross-sectional study included 140 institutionalized elderly people from the Madrid region (Spain) (65–90 years of age) whose diets were recorded using a precise weighing method over seven consecutive days. Energy and nutrient intakes were recorded and the GI and GL calculated. The participants’ affective capacity was assessed using the Geriatric Depression Scale (GDS). Subjects were grouped into non-depressed (GDS ≤ 5) and depressed (GDS > 5). Since GDS scores and gender were statistically associated (p < 0.01), the data were grouped considering this association.

Results

Dietary GI (51.09 ± 3.80) and GL (97.54 ± 13.46) were considered as medium. The dietary GL was significantly higher in the non-depressed (100.00 ± 12.13) compared with the depressed group (93.97 ± 14.04, p < 0.01). However, a similar GI was observed between non-depressed (51.50 ± 3.29) and depressed groups (50.52 ± 4.46). Additionally, participants with a dietary GL placed in the second and third tertiles had a 67.4 % and 65.3 %, respectively, less odds of suffering depression than those in the first tertile. GDS scores and dietary GL were inversely related; therefore, an increase in one unit in the dietary GL scale decreased the GDS score by 0.058 units.

Conclusions

Glyaemic load is associated with a lower odd of depression.     

Association of sleep problems and sleep duration with self-rated health and grip strength among older adults in India and China: results from the study on global aging and adult health (SAGE)

Background

Sleep is an important predictor of health and quality of life. This study examined the association between sleep problems and sleep duration with self-rated poor health and grip strength among respondents aged 50 years and above in India and China.Methods: The data for this study were derived from the first wave of WHO’s Study on Global Aging and Adult Health (SAGE), a nationally representative panel survey conducted in six LMICs. Grip strength and poor self-rated health were the main outcome variables, while sleep problems and sleep duration were the main predictors. Multivariate logistic regression models and ordinary least squares regression models were used to understand the association between sleep problems and sleep duration with poor self-rated health and grip strength.

Results

Sleep problems and sleep duration were strongly and significantly associated with poor self-rated health and grip strength in India and China. Compared to older adults with no sleep problems, the odds ratio for poor self-rated health among older adults with sleep problems was 4.86 (95% CI?=?4.12, 5.73, p?<?0.01) and 5.06 (95% CI?=?3.93, 6.51, p?<?0.01) higher for India and China, respectively. The likelihood of reporting poor health was higher among older adults who got ≤ 6 or 10+ h of sleep in both India and China. A negative and significant association was found between longer sleep duration and grip strength only in China (β?=??1.19, 95% CI?=??1.78, ?0.60, p?<?0.01).

Conclusion

We observed a significant association between sleep problems and sleep duration with poor self-rated health and grip strength. Results suggested that sleep problems are important factors in determining the health of older adults in low- and middle-income countries.

     

Effects of Modified Adeli Suit Therapy on Improvement of Gross Motor Function in Children With Cerebral Palsy

Objective

This study aimed to investigate the effects of the Modified Adeli suit therapy (MAST) on improvement of gross motor function in children with cerebral palsy (CP).

Methods

Thirty-six children with CP assigned by match pairs to three equal groups such as the MAST, the AST, and the Neurodevelopmental Treatment. They were treated for 4 weeks, 2 hr/d, 5 d/wk. All children were tested by the Gross Motor Function Measure (GMFM) at baseline, immediately before and 16 weeks after treatments.

Results

All groups had improvement in the GMFM after treatment (p < .01) and there were significant differences among groups (p < .01). In the follow-up study, no significant improvement in the GMFM was seen within groups (p > .05), but again there were significant differences among groups (p < .01).

Conclusion

The MAST was more effective than using either the AST or the Neurodevelopmental treatment on improvement of gross motor function in children with CP after treatment and at follow-up.     

Sleep apnoea in Australian men: disease burden,co-morbidities,and correlates from the Australian longitudinal study on male health

Background

Obstructive sleep apnoea is a common disorder with under-rated clinical impact, which is increasingly being recognised as having a major bearing on global disease burden. Men are especially vulnerable and become a priority group for preventative interventions. However, there is limited information on prevalence of the condition in Australia, its co-morbidities, and potential risk factors.

Methods

We used data from 13,423 adult men included in the baseline wave of Ten to Men, an Australian national study of the health of males, assembled using stratified cluster sampling with oversampling from rural and regional areas. Those aged 18–55 years self-completed a paper-based questionnaire that included a question regarding health professional-diagnosed sleep apnoea, physical and mental health status, and health-related behaviours. Sampling weights were used to account for the sampling design when reporting the prevalence estimates. Odds ratios were used to describe the association between health professional-diagnosed sleep apnoea and potential correlates while adjusting for age, country of birth, and body-mass index (BMI).

Results

Prevalence of self-reported health professional-diagnosed sleep apnoea increased from 2.2 % in age 18–25 years to 7.8 % in the age 45–55 years. Compared with those without sleep apnoea, those with sleep apnoea had significantly poorer physical, mental, and self-rated health as well as lower subjective wellbeing and poorer concentration/remembering (p?<?0.001 for all). Sleep apnoea was significantly associated with older age (p?<?0.001), unemployment (p?<?0.001), asthma (p?=?0.011), chronic obstructive pulmonary disease/chronic bronchitis (p?=?0.002), diabetes (p?<?0.001), hypercholesterolemia (p?<?0.001), hypertension (p?<?0.001), heart attack (p?<?0.001), heart failure (p?<?0.001), angina (p?<?0.001), depression (p?<?0.001), post-traumatic stress disorder (p?<?0.001), other anxiety disorders (p?<?0.001), schizophrenia (p?=?0.002), overweight/obesity (p?<?0.001), insufficient physical activity (p?=?0.006), smoking (p?=?0.005), and high alcohol consumption (p?<?0.001).

Conclusion

Health professional-diagnosed sleep apnoea is relatively common, particularly in older males. Associations between sleep apnoea and cardiovascular, metabolic, respiratory, and psychiatric disorders have important clinical and public health implications. As men are especially vulnerable to sleep apnoea as well as some of its chronic co-morbidities, they are potentially a priority group for health interventions. Modifiable lifestyle related factors such as smoking, alcohol consumption, level of physical activity and BMI are possible key foci for interventions.

     

A Low Glycemic Index and Glycemic Load Diet Decreases Insulin-like Growth Factor-1 among Adults with Moderate and Severe Acne: A Short-Duration, 2-Week Randomized Controlled Trial

Background

A high glycemic index (GI) and glycemic load (GL) diet may stimulate acne proliferative pathways by influencing biochemical factors associated with acne. However, few randomized controlled trials have examined this relationship, and this process is not completely understood.

Prevalence of adiposity and its association with sleep duration,quality, and timing among 9–12-year-old children in Guangzhou,China

Background

Short sleep duration has been reported to be associated with obesity in children, but findings are not consistent. Since few studies have examined the relationship between more complex sleep characteristics and obesity, we examined the association between adiposity and self-reported sleep duration, bedtime, and sleep quality in 9–12-year-old Chinese children using multilevel mixed models.

Effect of essential amino acid supplementation on quality of life, amino acid profile and strength in institutionalized elderly patients

Background & aims

This study assessed the efficacy of supplemented essential amino acids on depressive symptoms, nutrition, muscle function, daily physical activity, and health-related quality of life (HRQoL) of institutionalized elderly patients.

Methods

Forty-one patients (58.5% women; mean age 79.8 yrs) with sequelae of coronary artery disease (73%), femoral fracture (34%), were randomly assigned to receive oral essential amino acids 4 gr 2 times a day for 8 weeks or isocaloric placebo. Before randomization and 8 weeks after the protocol started, the following variables were measured: depressive symptoms (Geriatric Depression Scale, GDS), nutritional panel (Mini Nutritional Assessment, MNA; serum albumin and prealbumin levels), muscle strength (Hand Grip, HG), Activity Daily Life (ADL), Quality of Life (SF-36, HRQoL) and amino acid profile.

Results

Compared with the placebo group, EAA patients improved nutrition (MNA score 22.6 ± 1.5 post vs 21.8 ± 1.6 pre; p < 0. 04, albumin g/dl 4.04 ± 0.35 post vs 3.88 ± 0.3 pre; p < 0.01), GDS(score 10.3 ± 1.75 post vs 13.85 ± 3.37 pre; p < 0.001), HG (Kg 19.75 ± 1.7 post vs 18.68 ± 1.36 pre; p = 0.001), ADL (p < 0.04) and both physical and mental components of SF-36 (p < 0.002).

Conclusions

Oral supplementation with essential amino acids improved several determinants of quality of life in institutionalized elderly patients, including depressive symptoms, nutrition, muscle function and daily life activity.     

Methodology for adding glycemic index values to 24-hour recalls

Objective

To describe a standardized method to assign glycemic index (GI) values to food items, obtained from 3 × 24-h recalls among Aboriginal and Torres Strait Islander and non-Indigenous Australian children, which can be adapted for use with simple food composition databases.

Methods

Four published GI databases were used as the source of GI values. Changes were made to a previously published methodology for GI value assignment to accommodate the needs of the Many Rivers Diabetes Prevention Project.

Results

There were 1132 food items in the recall database. Two hundred nineteen (19.3%) food items were directly linked to the FoodWorks GI database and 545 (48.1%) items were assigned the GI value of a “closely related” food item in the four GI databases used. Among the top carbohydrate contributors, 113 (35.3%) items have a direct linkage with the FoodWorks GI database. The mean ± SEM dietary GI and glycemic load (GL) of the study population resulting from this methodology are 57.5 ± 0.3 and 143.4 ± 2.6, respectively.

Conclusion

This simple method provides opportunities for countries without food composition database that are comprehensive for GI/GL but which contain accurate information on carbohydrates in foods to assign high-quality GI values to food items in epidemiological studies based on 24-h recalls.     

Relationships among Dietary Intakes and Persistent Gastrointestinal Symptoms in Patients Receiving Enzyme Treatment for Genetic Sucrase-Isomaltase Deficiency

Background

Sucrose-isomaltase deficiency (SID) remains underdiagnosed. Absent or reduced enzyme activity promotes diarrhea, abdominal bloating, and flatulence from undigested and malabsorbed disaccharides. Frequency and severity of gastrointestinal symptoms may be associated with the type of carbohydrates consumed.

Leisure-time physical activity does not fully explain the higher body mass index in irregular-shift workers

Purpose

To elucidate the influence of leisure-time physical activity on body mass index (BMI), appetite-related hormones, and sleep when working irregular shifts.

Methods

A cross-sectional study was undertaken of 57 male truck drivers, 31 irregular-shift workers and 26 day-shift workers. Participants completed the International Physical Activity Questionnaire and were assessed for BMI. Subjects also provided a fasting blood sample for analysis of appetite-related hormones and wore an actigraphy device for seven consecutive days.

Results

Although leisure-time physical activity (LTPA) was generally low (<150 min/week) in both groups, the irregular-shift workers were more physically active than day-shift workers (99 ± 166 vs. 23 ± 76 min/week, p < 0.01). In spite of this, mean BMI of irregular-shift workers was 2 kg/m² greater than day-shift workers (28.4 ± 3.8 vs. 26.4 ± 3.6 kg/m², p = 0.04). Mean leptin concentration was 61 % higher in irregular-shift workers (5,205 ± 4,181 vs. 3,179 ± 2,413 pg/ml, p = 0.04). Among obese individuals, irregular-shift workers had higher leptin concentration (p < 0.01) and shorter sleep duration (p = 0.01) than obese day-shift workers.

Conclusion

Elevated BMI was associated with high leptin and low ghrelin levels in this population of irregular-shift workers. No influence of LTPA on appetite-related hormones or sleep duration was found. We conclude that moderate LTPA is insufficient to attenuate the higher BMI associated with this type of irregular-shift work in truck drivers.
