A community-based case-control study was performed to determine risk factors for mild ophthalmologic manifestations of vitamin A deficiency in urban Bangladeshi children. Cases were identified in children less than 14 years of age with night blindness with or without other signs of mild xerophthalmia detected in a house-to-house survey. Controls were randomly selected neighbors who lacked subjective and objective ophthalmologic evidence of vitamin A deficiency. Demographic characteristics that were independently associated with vitamin A deficiency in a logistic model included male gender, greater age (mean, 6.1 years in children with cases and 2.8 years in controls), and a greater number of children living with the family. After controlling for these demographic characteristics, poor intake of locally available vitamin A-rich foods, cessation of breast-feeding, and a recent history of protracted diarrhea remained associated with vitamin A deficiency. Maternal ignorance of prevention and control of vitamin A deficiency was also associated with increased risk. The results support programs that educate mothers to breast-feed and to provide appropriate food supplements and suggest that clinicians caring for children with chronic diarrhea should initiate vitamin A supplementation.

In Poland, like in many other countries, guidelines and certain restrictions were introduced in order to reduce the impact of the pandemic and curb the spread of the virus. These related to such behaviours as washing and disinfecting hands, wearing face masks in designated places, keeping social distance and frequently ventilating rooms. However, not all people follow the guidelines, which can lead to both health and social ramifications. The key objective of this study was an in-depth analysis of how safety rules (SR) were complied with in Poland during the initial pandemic period before the vaccines were rolled out, as well as determining factors that could affect the compliance with SR. METHODS. The study was conducted in the form of a series of cross-sectional surveys using the CATI method on a representative Polish sample in 8 rounds of interviews. Random sampling was applied. The first round was carried out from 2 to 6 July 2020, the last from 17 to 21 August 202...

The analysis was carried out for the total population, people aged 25–64 years and older population of people aged 65 years and more. The results of the analysis indicate a gradual improvement of the health status of the Polish population as evidenced by the declining fairly steadily mortality rates from main causes of death for people in the younger as well as older age groups. At the same time it should be stressed that, compared with the situation in the EU15 situation we observe in Poland cannot be regarded as satisfactory particularly in the case of men of working age. Certainly cardiovascular diseases have to be cons...

We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory ...

Our aim was to compare trends in total, HDL and non-HDL cholesterol and the total-to-HDL cholesterol ratio in Asian and Western countries. Methods We pooled 458 population-based studies with 82.1 million participants in 23 Asian and Western countries. We estimated changes in mean total, HDL and non-HDL cholesterol and mean total-to-HDL cholesterol ratio by country, sex and age group. Results Since ∼1980, mean TC increased in Asian countries. In Japan and South Korea, the TC rise was due to rising HDL cholesterol, which increased by up to 0.17 mmol/L per decade in Japanese women; in China, it was due to rising non-HDL cholesterol. TC declined in Western countries, except in Polish men. The decline was largest in Finland and Norway, at ∼0.4 mmol/L per decade. The decline in TC in most W...

We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.5-22.7) and 16.5 cm (13.3-19.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8-144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increas...

We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs-in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue. We used data from 751 studies including 4,372,000 adults from 146 ...

We assessed the effect of different diagnostic definitions on both the population prevalence of diabetes and the classification of previously undiagnosed individuals as having diabetes versus not having diabetes in a pooled analysis of data from population-based health examination surveys in different regions. We used data from 96 population-based health examination surveys that had measured at least two of the biomarkers used for defining diabetes. Diabetes was defined using HbA1c (HbA1c ≥6·5% or history of diabetes diagnosis or using insulin or oral hypoglycaemic drugs) compared with either FPG only or FPG-or-2hOGTT definitions (FPG ≥7·0 mmol/L or 2hOGTT ≥11·1 mmol/L or history of diabetes or using insulin or oral hypoglycaemic drugs). We calculated diabetes prevalence, taking into account complex survey d...

Authors are going to estimate the prevalence of a bad frame of mind and neurosis among Polish adult people and try to appoint the relationships between psychiatric disorders and gender and place of residence. We estimated results in 49 provinces. There were significant differences between east and west Poland. People who live in eastern provinces have a worse psychological condition than western. Women have higher rate of these this psychiatric problems. We also found a major correlation between dissemination of a bad frame of mind and neurosis among men and women.

The 5-year follow-up study covered a probability sample of 4355 adult inhabitants. Data on respiratory symptoms and lung function in addition to variables related to environmental and socioeconomic factors were included. To assess the separate and joint effects of the chosen environmental factors on chronic chest problems, the multiple logistic regression analysis has been carried out. As expected, smoking habit was the strongest single of the factors related to the persistence of the respiratory symptoms. The effect of smoking was more marked in men than in women and this can be attributed to longer duration of smoking and more cigarettes smoked daily by men. Out of all considered adverse occupational factors only chemicals increased the risk ...

Adults also suffer from symptoms of attention-deficit/hyperactivity disorder. Prevalence estimates of ADHD in adult community samples (5%) are based on American and West-European studies. Most of research though is concentrated on early ADHD symptoms. There are no sufficient data on clinical manifestation and scale of this problem in Poland.Objectives To assess prevalence (life and 12-month), access to psychiatric care and other clinical and sociodemographic aspects of ADHD in adult population in Poland (both contemporary and retrospective). The first Polish nationwide survey, Epidemiology of Mental Disorders and Access to Care (EZOP, Poland)” was included in the WHO's WMH.AimsThe aim of this paper is to present collected data on ADHD in community sample.Methods Composite International Diagnostic Interview (cidi capi v.3.1) was administered in random sample of Poles aged 18–65 (n = 10000). Data was collected from November 2010 to March 2011 by trained Millward Brown SMG/KRC interviewers.ResultsResponse rate is 50.4%. Prevalence estimated on the basis of retrospective reports in Screening Section is 2.2% for attention-deficit symptoms (2.5% for men and 1.9% for women) and 2.8% for hyperactivity symptoms (respectively 3.2% and 2.8%). Further analysis are in progress and detailed results will be known till December 2011.Conclusions Presented study will allow to introduce data on relation between intensity of early ADHD symptoms and it's later clinical manifestation. The identification of demographic factors influencing the course of the disorder and patterns of treatment will be possible.
