Cardiovascular disease (CVD) is often thought to be a problem of wealthy, industrialized nations. The term “cardiovascular disease” is used throughout the report to refer to cardiac disease, vascular diseases of the brain and kidney, and peripheral vascular disease. The report’s main focus is ...on the major contributors to global CVD mortality, coronary heart disease and stroke, and on the major modifiable risk factors for cardiovascular diseases. In fact, as the leading cause of death worldwide, CVD now has a major impact not only on developed nations but also on low and middle income countries, where it accounts for nearly 30 percent of all deaths. The terms “developed” and “high income countries” are used interchangeably throughout the report to refer to countries classified by the World Bank as high income economies. The terms “developing” and “low and middle income countries” are used interchangeably throughout the report to refer to countries classified by the World Bank as low, lower middle, and upper middle income economies. The increased prevalence of risk factors for CVD and related chronic diseases in developing countries, including tobacco use, unhealthy dietary changes, reduced physical activity, increasing blood lipids, and hypertension, reflects significant global changes in behavior and lifestyle. The term “chronic diseases” is used throughout the report to refer to CVD and the following related chronic diseases that share many common risk factors: diabetes, cancer, and chronic respiratory disease. These changes now threaten once-low-risk regions, a shift that is accelerated by industrialization, urbanization, and globalization. The potentially devastating effects of these trends are magnified by a deleterious economic impact on nations and households, where poverty can be both a contributing cause and a consequence of chronic diseases. The accelerating rates of unrecognized and inadequately addressed CVD and related chronic diseases in both men and women in low and middle income countries are cause for immediate action.

The article investigates the global burden and risk factors of chronic obstructive pulmonary disease (COPD). It emphasizes that COPD is a leading cause of morbidity and mortality worldwide, with significant health and economic impacts. The study identifies smoking as the primary risk factor, but als...o highlights other contributors such as occupational exposure, air pollution, and respiratory infections. The authors discuss variations in COPD prevalence and mortality rates across different regions, influenced by socioeconomic and environmental factors. The article calls for comprehensive public health strategies to reduce exposure to risk factors and improve early diagnosis and management to curb the global impact of COPD.

The epidemiology of wheeze in children, when assessed by questionnaires, is dependent on parents' understanding of the term “wheeze”.
In a questionnaire survey of a random population sample of 4,236 children aged 6–10 yrs, parents' definition of wheeze was assessed. Predictors of a correct ...definition were determined and the potential impact of incorrect answers on prevalence estimates from the survey was assessed.
Current wheeze was reported by 13.2% of children. Overall, 83.5% of parents correctly identified “whistling or squeaking” as the definition of wheeze; the proportion was higher for parents reporting wheezy children (90.4%). Frequent attacks of reported wheeze (adjusted odds ratio (OR) 3.0), maternal history of asthma (OR 1.5) and maternal education (OR 1.5) were significantly associated with a correct answer, while the converse was found for South Asian ethnicity (OR 0.6), first language not English (OR 0.6) and living in a deprived neighbourhood (OR 0.6).
In summary, the present study showed that misunderstanding could lead to an important bias in assessing the prevalence of wheeze, resulting in an underestimation in children from South Asian and deprived family backgrounds. Prevalence estimates for the most severe categories of wheeze might be less affected by this bias and questionnaire surveys on wheeze should incorporate measures of parents' understanding of the term wheeze.

The aim of the present study was to predict which patients with severe or difficult-to-treat asthma are at highest risk for healthcare utilisation can be predicted so as to optimise clinical management. Data were derived from 2,821 adults with asthma enrolled in The Epidemiology and Natural History ...of Asthma: Outcomes and Treatment Regimens (TENOR) study. Multiple potential predictors were assessed at baseline using a systematic algorithm employing stepwise logistic regression. Outcomes were asthma-related hospitalisations or emergency department (ED) visits within 6 months following baseline.

Considerable energy has been expended over the last two decades in developing methods for identifying the presence of asthma among participants in population studies. The objective of this endeavour has commonly been to enable epidemiological research on risk factors for asthma, with the ultimate ai...m of preventing the disease. However, there are other reasons for measuring the prevalence of asthma in populations, including the desire to assess the burden of disease attributable to asthma, to track changes over time, and to compare the prevalence among population groups defined by geographical, demographic or social factors. Two major international collaborative studies arising from this work have made major contributions to our knowledge about asthma
