To investigate the time trends of the prevalence and predictors of acute gastroenteritis (AGE) in the United States from 2005 to 2014 using nationally representative data.
AGE results in numerous visits to emergency departments and outpatient clinics annually in the United States with the estimated attributable cost to the US economy up to $145 billion dollars. However, time trends and predictors of AGE are not fully understood.
Data were obtained from the National Health and Nutrition Survey (NHANES) 2005 to 2014, a nationally representative health survey. AGE was defined by a medical question (Do you have a stomach or intestinal illness with vomiting or diarrhea that started during last 30 d?). Prevalence of AGE was estimated in the total population as well as by selected demographic variables. Predictors of AGE and time trends of prevalence over survey periods were also investigated.
Overall monthly prevalence of AGE was 8.31% (95% confidence interval, 7.81-8.81), corresponding to 22.8 million people. AGE was associated with a younger age group, the highest in ages 0 to 9 years old, females, winter to early spring season, US born, divorced/separated/widowed individuals, current smokers, heavy alcohol users, and low household income. In the trends analyses, the prevalence of AGE significantly decreased over the study periods: 10.23% in 2005 to 2006, 9.89% in 2007 to 2008, 7.58% in 2009 to 2010, 6.44% in 2011 to 2012, and 7.47% in 2013 to 2014 (trend P<0.001).
In the United States from 2005 to 2014, the monthly prevalence of AGE was 8.31% and has been significantly decreasing over time.
利用具有全国代表性的数据，调查2005年至2014年美国急性胃肠炎（AGE）的患病率时间趋势及其预测因素。
在美国，急性胃肠炎每年导致大量患者前往急诊科和门诊就诊，据估计给美国经济造成的成本高达1450亿美元。然而，急性胃肠炎的时间趋势和预测因素尚未完全明确。
数据来源于2005年至2014年的美国国家健康与营养调查（NHANES），这是一项具有全国代表性的健康调查。急性胃肠炎通过一个医学问题来定义（您在过去30天内是否患有伴有呕吐或腹泻的胃肠疾病？）。对总人口以及选定的人口统计学变量进行急性胃肠炎患病率估计。还调查了急性胃肠炎的预测因素以及调查期间患病率的时间趋势。
急性胃肠炎的总体月患病率为8.31%（95%置信区间，7.81 - 8.81），相当于2280万人。急性胃肠炎与较年轻年龄组、0至9岁年龄段最高、女性、冬末至早春季节、在美国出生、离婚/分居/丧偶者、当前吸烟者、大量饮酒者以及家庭收入低有关。在趋势分析中，急性胃肠炎的患病率在研究期间显著下降：2005年至2006年为10.23%，2007年至20年08为9.89%，2009年至2010年为7.58%，2011年至2012年为6.44%，2013年至2014年为7.47%（趋势P<0.001）。
在2005年至2014年的美国，急性胃肠炎的月患病率为8.31%，且随时间显著下降。
