概括
2008年以后出生的巴西儿童更高,这表明儿童健康状况有所改善. 然而,儿童超重和肥胖的患病率仍然很高,需要继续关注公共卫生.
科学领域:
- 儿科 儿科 儿科
- 公共卫生 公共卫生
- 增长监测 增长监测 增长监测
背景情况:
- 关于低收入和中等收入国家近期儿童成长趋势的证据有限.
- 调查2000年后出生的巴西儿童身高和体重指数 (BMI) 轨迹的变化.
研究的目的:
- 分析巴西儿童身高和BMI的特定年龄增长轨迹.
- 为了比较2000年以后在两个不同的时期出生的儿童之间的生长模式.
主要方法:
- 利用基于人口的队列,超过570万名巴西儿童 (3至10岁以下) 使用链接的行政数据库.
- 包括2001-2014年的纵向数据,包括超过2000万次观测.
- 应用随机效应的分数多项式模型来估计平均身高和BMI轨迹.
主要成果:
- 2008-2014年间出生的孩子比2001-2007年出生的孩子高 (0.15个z-score男孩,0.12个女孩),平均身高增加1厘米.
- 平均BMI轨迹的变化很小,z分数略有增加 (0.06男孩,0.04女孩).

Longitudinal Studies
157
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Population Growth
25.1K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Longitudinal Research
12.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Nature and Nurture
20.5K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Bias in Epidemiological Studies
254
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Cross-Sectional Research
11.3K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
