Body mass index, waist to hip ratio and waist/height in adult Polish women in relation to their education, place of residence, smoking and alcohol consumption

Meta-analytic evidence for a sex-diverging association between alcohol use and body mass index

Alcohol use is an important health issue and has been suggested to contribute to the burden produced by obesity. Both alcohol use and obesity are subject to sex differences. The available studies on the relationship between alcohol use and body mass index (BMI) report inconsistent results with positive, negative, and null findings which requests a meta-analytic approach. Therefore, we conducted a meta-analysis of case-control, cohort, and cross-sectional studies. The systematic literature search and data extraction was performed by 3 independent raters. We conducted sex-separated meta-analyses and -regressions to investigate how alcohol consumption associates with BMI. Our systematic literature search resulted in 36 studies with 48 data sets (N_men = 172,254; k_men = 30; N_women = 24,164; k_women = 18; N_{unknown sex} = 672,344; k_{unknown sex} = 24). Alcohol use was associated with higher BMI in men (g = 0.08 [0.07; 0.09]) and lower BMI in women (g = - 0.26 [- 0.29; - 0.22]). Moreover, we found the amount of daily alcohol intake in men (β = 0.001 [0.0008; 0.0014]) and ethnicity in women (g[Caucasians] = - 0.45 versus g[Asians] = - 0.05; z = 11.5, p < 0.0001) to moderate these effects. We here identified sex-diverging relationships between alcohol use and BMI, found daily alcohol intake and ethnicity to sex-specifically moderate these effects, and argue that sex-specific choice of beverage type and higher amount of daily alcohol use in men than in women account for these observations. Future research is needed to provide empirical evidence for the underlying mechanisms.

Lean diabetes in middle-aged adults: A joint analysis of the German DIVE and DPV registries

AIMS

To assess differences in demographics, treatment and outcome of lean (LD) compared to overweight and obese people with diabetes clinically classified as type 2 diabetes mellitus (T2DM).

MATERIALS AND METHODS

We combined data from the German DIVE (Diabetes Versorgungs-Evaluation) and DPV (Diabetes-Patienten-Verlaufsdokumentation) databases to produce a large cohort of people with T2DM. The characteristics of people with Body Mass Index (BMI) <25 kg/m2, ≥25-30 kg/m2 and ≥30 kg/m2 aged 30 to 50 years were compared, including demographics, cardiovascular (CV) risk factors, comorbidities and outcomes.

RESULTS

A total of 37,870 people were included in the analysis, 3,191 of these (8.4%) had a BMI < 25 kg/m2. LD reported more nicotine (41.6% of 2,070 vs. 38.1% of 6,070 and 33.4% of 16,823; P<0.001)and alcohol consumption (12.0% of 1,282, 10.3% of 3,594 and 6.6% of 9,418; P<0.001)compared to overweight and obese people. More LD were treated with insulin in comparison to the other subgroups (short acting insulin 33.1% of 3,191 vs. 28.4% of 9,234 and 28.0% of 25,445; P <0.001; long acting insulin 31.3% of 3,191 vs. 28.9% of 9,234 and 29.3% of 25,445; P = 0.043). Regression models adjusted for age, gender and diabetes duration showed a 2.50 times higher odds ratio (OR) for hypoglycemia and a 2.52 higher OR for mortality in LD compared to the BMI subgroup ≥30 kg/m2.

CONCLUSIONS

LD is associated with an increased risk of hypoglycaemia and death. Patients are characterized by male gender, lifestyle habits as smoking and alcohol consumption while cardiovascular comorbidities are less important. In comparison to patients of the other weight groups they are treated with insulin more often and considerably less with metformin.

Alcohol Consumption and Obesity: An Update

Recreational alcohol intake is a widespread activity globally and alcohol energy (7 kcal/g) can be a contributing factor to weight gain if not compensated for. Given that both excessive alcohol intake and obesity are of public health interest, the present paper provides an update on the association between alcohol consumption and body weight. In general, recent prospective studies show that light-to-moderate alcohol intake is not associated with adiposity gain while heavy drinking is more consistently related to weight gain. Experimental evidence is also mixed and suggests that moderate intake of alcohol does not lead to weight gain over short follow-up periods. However, many factors can explain the conflicting findings and a better characterization of individuals more likely to gain weight as a result of alcohol consumption is needed. In particular, individuals who frequently drink moderate amounts of alcohol may enjoy a healthier lifestyle in general that may protect them from weight gain. In conclusion, despite the important limitations of current studies, it is reasonable to say that alcohol intake may be a risk factor for obesity in some individuals, likely based on a multitude of factors, some of which are discussed herein.

Associations of physical activity and inactivity with body tissue composition among healthy Polish women and women after mastectomy

The aim of the study is to determine the relationship between physical activity and body composition among healthy women and women who have had mastectomy. This is in order to establish whether physical activity of women after breast cancer treatment improves composition and distribution of body mass components to a degree which will allow to achieve the body composition of healthy women. Research material consists of anthropometric measurements (body height, weight) of women and bioelectric impedance analysis (BIA) of body composition (using Akern - BIA 101 composition analyzer). Intensity of activity was assessed using the Physical Activity International Questionnaire. The sample consisted of 76 healthy women (active 44.74%, inactive 55.26%) and 70 females after mastectomy (54.29% and 45.71%, respectively). Mean chronological age of women after mastectomy was 53.40 years, SD=7.55, and of the healthy ones 52.38 years SD=11.01). A significant difference in body composition was noted among active and inactive women after mastectomy; namely the active females had lower weight (by approximately 12 kg), body mass index (BMI), level of fat mass (by approximately 8%) and (by approximately 5%) total body water. The active healthy women had 6% less fat mass, almost 4% more body water and 6% more fat free mass. Programmed physical activity undertaken by women after mastectomy is recommended and produces good results in the form of reduction of excessive body fat tissue. Through physical activity these women are able to achieve the same level of fat mass as healthy women.

Prediction of body mass index status from voice signals based on machine learning for automated medical applications

OBJECTIVES

The body mass index (BMI) provides essential medical information related to body weight for the treatment and prognosis prediction of diseases such as cardiovascular disease, diabetes, and stroke. We propose a method for the prediction of normal, overweight, and obese classes based only on the combination of voice features that are associated with BMI status, independently of weight and height measurements.

MATERIALS AND METHODS

A total of 1568 subjects were divided into 4 groups according to age and gender differences. We performed statistical analyses by analysis of variance (ANOVA) and Scheffe test to find significant features in each group. We predicted BMI status (normal, overweight, and obese) by a logistic regression algorithm and two ensemble classification algorithms (bagging and random forests) based on statistically significant features.

RESULTS

In the Female-2030 group (females aged 20-40 years), classification experiments using an imbalanced (original) data set gave area under the receiver operating characteristic curve (AUC) values of 0.569-0.731 by logistic regression, whereas experiments using a balanced data set gave AUC values of 0.893-0.994 by random forests. AUC values in Female-4050 (females aged 41-60 years), Male-2030 (males aged 20-40 years), and Male-4050 (males aged 41-60 years) groups by logistic regression in imbalanced data were 0.585-0.654, 0.581-0.614, and 0.557-0.653, respectively. AUC values in Female-4050, Male-2030, and Male-4050 groups in balanced data were 0.629-0.893 by bagging, 0.707-0.916 by random forests, and 0.695-0.854 by bagging, respectively. In each group, we found discriminatory features showing statistical differences among normal, overweight, and obese classes. The results showed that the classification models built by logistic regression in imbalanced data were better than those built by the other two algorithms, and significant features differed according to age and gender groups.

CONCLUSION

Our results could support the development of BMI diagnosis tools for real-time monitoring; such tools are considered helpful in improving automated BMI status diagnosis in remote healthcare or telemedicine and are expected to have applications in forensic and medical science.

Smoking and abdominal fat in blood donors

OBJECTIVE

To assess the association between smoking and abdominal fat among male blood donors.

METHODS

This was a cross-sectional study involving 1,235 adult male blood donors (age, 20-59 years) in the city of Cuiabá, Brazil. Socioeconomic, demographic, and anthropometric data, as well as information on the lifestyle of the participants, were collected. In this study, waist circumference and waist-to-hip ratio were used as markers of abdominal fat. The association between these two markers and smoking was analyzed by multiple linear regression in separate models, adjusted for potential confounders.

RESULTS

Of the 1,235 respondents, 273 (22.1%) reported being smokers, and, of those, 99 (36.3%) reported smoking more than 15 cigarettes per day. The average body mass index was lower among smokers than among nonsmokers (p < 0.001). In the multiple linear regression analyses, smoking was associated with waist circumference and waist-to-hip ratio for smokers of 6-10 cigarettes/day and of > 11 cigarettes/day.

CONCLUSIONS

In our sample, smoking was positively associated with indicators of abdominal fat, regardless of potential confounding factors, including the consumption of alcoholic beverages.

Alcohol consumption and body weight: a systematic review

Based on the fact that energy content in 1 gram of alcohol is 29 kJ or 7.1 kcal, alcohol consumption can lead to weight gain. The present review was conducted to analyze the effects of alcohol consumption on body weight. A search of the Medline database for the period 1984 to March 2010 was conducted to identify cross-sectional, prospective cohort studies and intervention trials investigating the relationship between alcohol consumption and the risk of weight gain. Thirty-one publications were selected on the basis of relevance and quality of design and methods. The findings from large cross-sectional studies as well as from well-powered, prospective, cohort studies with long periods of follow-up were contradictory. Findings from short-term experimental trials also did not show a clear trend. The overall results do not conclusively confirm a positive association between alcohol consumption and weight gain; however, positive findings between alcohol intake and weight gain have been reported, mainly from studies with data on higher levels of drinking. It is, therefore, possible that heavy drinkers may experience such an effect more commonly than light drinkers. Moreover, light-to-moderate alcohol intake, especially wine intake, may be more likely to protect against weight gain, whereas consumption of spirits has been positively associated with weight gain. Further research should be directed towards assessing the specific roles of different types of alcoholic beverages. Studies should also take the effect of consumption patterns into account. In addition, a potential effect modifier that has not been evaluated before but might be important to consider is the subjects' previous tendency to gain weight.

Type of alcoholic beverage and incidence of overweight/obesity in a Mediterranean cohort: the SUN project

OBJECTIVE

The effects of alcohol on body weight might be modulated by the total amount of alcohol intake and type of alcoholic beverage. However, available results are contradictory. There is a scarcity of studies on this topic in Mediterranean areas where wine consumption is high. We prospectively evaluated the association between the type of alcoholic beverage intake and weight change in a Mediterranean cohort.

METHODS

We followed for an average of 6.1 y 9318 adults without previous chronic disease at baseline. Validated data on diet including alcohol consumption were collected at baseline. Weight was recorded at baseline and updated every 2 y during follow-up. The outcomes were average weight gained every year and incidence of overweight/obesity after a 6-y follow-up.

RESULTS

During follow-up, 1006 incident cases of overweight/obesity were identified in participants with normal weight at baseline. Beer and spirits consumption (≥7 drinks/wk) was associated with a +119 g/y (95% confidence interval +27 to +212) higher average yearly weight gain after adjusting for relevant confounders. It was also associated with a higher risk of developing overweight/obesity compared with non-drinkers. No association between wine consumption and yearly weight change or the risk of developing overweight/obesity was apparent.

CONCLUSION

The type of alcoholic beverage can modulate the effect of alcohol intake on the risk of developing overweight/obesity.

Body mass index, waist-to-hip ratio and waist/height in adult population from Backa and Banat - the Republic of Serbia

BACKGROUND

Nutritional status is vital in the assessment of physical fitness and health status of populations.

AIM

This study aimed to describe relationships between BMI, waist-to-hip ratio (WHR) and waist/height (W/Ht) and factors such as education, residence, origin and ethnic belonging among adults in Backa and Banat.

SUBJECTS AND METHODS

The study was conducted in 47 villages in the north of Serbia. The tested group consisted of 4247 individuals, aged 20+.

RESULTS

The problem of overweight and obesity was more common among men (66%) than women (49.71%). In the group with normal BMI, the majority of men and women were characterized by normal WHR and W/Ht values, but among them there were also groups with incorrect WHR (males >or= 0.95, females >or= 0.8) and W/Ht (>or= 0.5). Socio-demographic factors had a little impact on BMI, WHR and W/Ht in men in certain age groups while their impact was higher in women. These factors, especially education and origin, had a significant impact on nutritional status in young and middle-aged women, whereas they were not significant in older female participants (> 60).

CONCLUSION

Despite the fact that this part of the country has undergone intensive social changes since the last decade of 20th century, the nutritional status of the population has not significantly changed.

BMI, life-style and psychological conditions in a sample of elderly Italian men and women

OBJECTIVES

To identify the relationship among cognitive status, psychological conditions, anthropometric measurements and life-style in a sample of elderly Italian men and women.

METHODS

Three hundred and six volunteers for ZINCAGE Project recruited. The sample was made up of healthy older adults living in the Marche Region aged 65 and over. All elderly were given a complete medical, anthropometric assessment, and psycho-social evaluation.

RESULTS

Overall, the participants perceived themselves to be in very good or good (22%) or fair (69%) health; only 9% reported a poor health status. The 46% of the sample fell within the normal body mass index (BMI) range, though 38% were overweight, 12% were obese, and only 4% were underweight. In both sexes, BMI significantly decreased with age (p<0.001). BMI was positively associated with performing sedentary activities (r=0.188; p<0.001). Levels of both sedentary (r=0.221; p<0.001) and non-sedentary (r=0.258; p<0.001) leisure activities were positively associated with education level (p<0.05). It was found that lower scores of physical activity were associated to higher scores of Geriatric Depression Scale (r=-0.425; p<0.01), lower scores of Mini Mental State Examination (r=0.266; p<0.001) and higher score of Perceived Stress Scale (r=-0.131; p<0.05).

CONCLUSION

Men and women lead different lifestyles and have a different psychological status, with advancing age consequently stressing the need for healthy lifestyle programmes particularly in the case of overweight and obese elderly people.

Alcohol and injury in Poland: review and training recommendations

Background

Alcohol plays a significant role in accidents, injuries, and their outcomes. According to the World Health Organization (WHO), there are 76.3 million people with alcohol use disorders worldwide; in 2000, 1.8 million deaths and loss of 58.3 million disability-adjusted life years were attributed to alcohol.

Methods

Although the association between alcohol consumption and trauma-related morbidity and mortality is well-documented, particularly in the US, there is much less information on trauma and alcohol in Poland, a country undergoing unprecedented economic and cultural changes stemming from entry into the European Union (EU) in the midst of a global recession.

Results

Injury is the third leading cause of death in Poland. Rates for all injuries in Poland are higher than in the rest of the EU. Alcohol is one of the greatest risk factors for disease and injury among men and one of the top ten health and injury risk factors for women. In this paper we review the last 10 years of research on injury and alcohol in Poland.

Conclusion

Recommendations are provided for next steps with regard to training health care professionals in emergency medical settings to address this serious and growing problem.

Body mass index in Serbian Roma

Stature and body mass were measured in 346 individuals belonging to three Roma groups from metropolitan Belgrade western Serbia. As with the majority of Serbian Roma, the participants in this study have been historically disadvantaged and their situation was further aggravated during the recent political crises. Surprisingly, the body mass index (BMI) of Serbian Roma is relatively high compared with western Europeans and is inconsistent with the view that Serbian Roma are predisposed to high rates of chronic energy deficiency ( approximately 4%). While the majority of individual Roma display BMI values within the normal range (WHO, 1995), certain groups have a moderate to high proportion of individuals ( approximately 35%) who could be classified as overweight and some who approach at-risk levels for clinical obesity.
