Prevalence and Trends of Overweight and Obesity in European Children From 1999 to 2016: A Systematic Review and Meta-analysis.

ABSTRACT: Importance:Studies of trends in excess weight among European children throughout the last few decades have rendered mixed results. Additionally, some studies were outdated, were based on self-reported weight and height, or included only a few European countries. Objective:To assess prevalence trends in measured overweight and obesity among children across Europe from 1999 to 2016 using a systematic methodology. Data Sources:MEDLINE, Embase, CINAHL, and Web of Science were searched from their inception until May 2018. Moreover, searches were conducted on health institutions' websites to identify studies not published in scientific journals. Study Selection:The inclusion criteria were: (1) studies reporting the population-based prevalence of excess weight (overweight plus obesity) or obesity according to body mass index cutoffs proposed by the International Obesity Task Force; (2) cross-sectional or follow-up studies; and (3) studies including populations aged 2 to 13 years. Data Extraction and Synthesis:Literature review and data extraction followed established guidelines. The Mantel-Haenszel method was used to compute the pooled prevalence estimates and their 95% CI whenever there was no evidence of heterogeneity (I2?

Project description:CONTEXT:The prevalence of childhood obesity increased in the 1980s and 1990s but there were no significant changes in prevalence between 1999-2000 and 2007-2008 in the United States. OBJECTIVES:To present the most recent estimates of obesity prevalence in US children and adolescents for 2009-2010 and to investigate trends in obesity prevalence and body mass index (BMI) among children and adolescents between 1999-2000 and 2009-2010. DESIGN, SETTING, AND PARTICIPANTS:Cross-sectional analyses of a representative sample (N = 4111) of the US child and adolescent population (birth through 19 years of age) with measured heights and weights from the National Health and Nutrition Examination Survey 2009-2010. MAIN OUTCOME MEASURES:Prevalence of high weight-for-recumbent length (?95th percentile on the growth charts) among infants and toddlers from birth to 2 years of age and obesity (BMI ?95th percentile of the BMI-for-age growth charts) among children and adolescents aged 2 through 19 years. Analyses of trends in obesity by sex and race/ethnicity, and analyses of trends in BMI within sex-specific age groups for 6 survey periods (1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, and 2009-2010) over 12 years. RESULTS:In 2009-2010, 9.7% (95% CI, 7.6%-12.3%) of infants and toddlers had a high weight-for-recumbent length and 16.9% (95% CI, 15.4%-18.4%) of children and adolescents from 2 through 19 years of age were obese. There was no difference in obesity prevalence among males (P = .62) or females (P = .65) between 2007-2008 and 2009-2010. However, trend analyses over a 12-year period indicated a significant increase in obesity prevalence between 1999-2000 and 2009-2010 in males aged 2 through 19 years (odds ratio, 1.05; 95% CI, 1.01-1.10) but not in females (odds ratio, 1.02; 95% CI, 0.98-1.07) per 2-year survey cycle. There was a significant increase in BMI among adolescent males aged 12 through 19 years (P = .04) but not among any other age group or among females. CONCLUSION:In 2009-2010, the prevalence of obesity in children and adolescents was 16.9%; this was not changed compared with 2007-2008.

Project description:Background: The growing burden of non-communicable diseases (NDC), particularly in low-and middle-income countries, poses a significant threat to global health. Obesity and overweight constitute major risk factors of NCDs such as heart diseases, diabetes, and kidney disease, and as a result, contribute significantly to the development of chronic morbidities, reduced quality of life, and increased risk of premature death. This study described evidence on the prevalence, incidence, and trends of childhood overweight and obesity in sub-Sahara Africa (SSA).Methods: We conducted a systematic scoping review employing the Arksey and O'Malley framework, Levac et al. recommendations, and the Joanna Briggs Institute guidelines. To obtain relevant published articles for this review, we performed a comprehensive keywords search in PubMed, Google Scholar, Web of Science, and CINAHL via EBSCOhost platform for studies published between 2009 and June 2019. Guided by the eligibility criteria, title and abstracts, as well as the full-text articles were independently screened in parallel by two investigators. All relevant data were independently extracted by two investigators using a piloted form designed in Microsoft and thematic analysis conducted.Results: Of the 81 included studies obtained from 250,148 potentially eligible articles, the majority (25) conducted in South Africa followed by 18 in Nigeria. Six studies were conducted in Ethiopia (6), Tanzania (5), Kenya (4), Cameroon (4), Ghana (3), Uganda (2), Mozambique (2), and Sudan (2). One study each was conducted in Botswana, Gambia, Lesotho, Mauritius, Seychelles, Togo, and Zimbabwe. The remaining three articles were multi-country studies. Most (81.5%) of the included studies were cross-sectional surveys and the majority (79) focused on both male and female participants. The majority (80/81) of the included studies reported on the prevalence of childhood overweight/obesity, 8 on the trends of childhood overweight/obesity, and one presented evidence on the incidence of childhood overweight and obesity in SSA.Conclusion: This review demonstrates limited studies on childhood overweight/obesity in most SSA countries although the included studies suggest an increasing burden. Considering the consequences of childhood obesity, there is a need for more primary researches to inform policies decision and implementation to halt the rise of childhood obesity/overweight in SSA.

Project description:BackgroundUpdating national trends in diabetes management is important for identifying areas of progress and remaining gaps in diabetes care.ObjectiveEvaluate trends in diabetes management.DesignThree nationally representative, serial cross-sectional surveys (National Health and Nutrition Examination Survey [n = 5800], National Health Interview Survey [n = 48,519], and Behavioral Risk Factor Surveillance System [n = 741,497]) were used to estimate trends in diabetes management from 1999 to 2016.ParticipantsNon-pregnant US adults (aged ≥ 18 years) diagnosed with diabetes.Main measuresAmerican Diabetes Association's general recommendations for glycemic and cardiovascular risk factor control, medication usage, physical activity, preventive practices, and dietary intake.Key resultsFrom 1999 to 2016, the proportion of US adults with diabetes who attained glycemic control (HbA1c < 7.0%) followed a quadratic trend (49.6% in 1999-2004 to 58.6% in 2005-2010 to 55.8% in 2011-2016, P < 0.05 for trend). Control of blood pressure (< 140/90 mmHg) and lipids (LDL cholesterol < 100 mg/dl) increased by 6.6 and 18.7 percentage points, respectively (P < 0.05 for trends). The proportion that attained glycemic, blood pressure, and lipid control followed a quadratic trend (13.3% in 1999-2004 to 24.8% in 2005-2010 to 20.2% in 2011-2016, P < 0.05 for trend). Use of antidiabetic, antihypertensive, and statin medication among those who were eligible rose by 8.6, 5.0, and 24.0 percentage points, respectively (P < 0.05 for trends). Aerobic inactivity declined 7.1 percentage points, while adherence to aerobic activity (≥ 150 min/week) and resistance training (≥ 2 times/week) recommendations grew 3.4 and 3.2 percentage points, respectively (P < 0.05 for trends). Engagement in preventive practices (e.g., receipt of vaccinations) consistently increased for 6 out of 8 outcomes. However, the adherence to saturated fat (< 10% of total daily calories) and sodium (< 2300 mg/day) recommendations fell by 6.5 and 5.2 percentage points (P < 0.05 for trends).ConclusionsDespite notable improvements, declines in glycemic control and adherence to dietary recommendations may be growing challenges in diabetes care.
