Cigarette Smoking During Pregnancy: United States, 2016
NCHS Data Brief
|March 13, 2018
Summary
Maternal smoking during pregnancy is linked to adverse infant outcomes. This study analyzes 2016 U.S. birth data to report smoking prevalence by state and demographics.
Area of Science:
- Public Health
- Epidemiology
- Reproductive Health
Background:
- Maternal tobacco use during pregnancy is a significant risk factor for adverse infant and child outcomes.
- These outcomes include low birthweight, preterm birth, and congenital anomalies.
- Understanding the prevalence of smoking during pregnancy is crucial for public health interventions.
Purpose of the Study:
- To report the prevalence of cigarette smoking at any time during pregnancy among women who gave birth in the United States in 2016.
- To examine variations in smoking prevalence by state of residence.
- To analyze smoking prevalence based on maternal race and Hispanic origin, age, and educational attainment.
Main Methods:
- Utilizes the 2016 natality data file from the U.S. Standard Certificate of Live Birth.
- This data file includes newly revised items on maternal cigarette smoking before and during pregnancy.
- Data covers all states and the District of Columbia.
Main Results:
- Presents the prevalence of cigarette smoking at any time during pregnancy for births in 2016.
- Provides state-specific prevalence data for maternal smoking.
- Details prevalence by maternal race and Hispanic origin, age, and educational attainment.
Conclusions:
- The 2016 natality data provides comprehensive national and state-level insights into maternal smoking during pregnancy.
- This data is essential for targeted public health strategies to reduce smoking during pregnancy.
- Further research can explore the impact of demographic factors on smoking prevalence and subsequent interventions.

Measurement: Standard Units
82.3K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Mechanical engineering is one of the oldest branches of engineering. It deals with designing, analyzing, and manufacturing machines and mechanical systems. To ensure precise and accurate calculations, units of measurement are used. They provide a standard system for expressing and comparing physical quantities.

The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...

Motor Units

A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.
