Summary
This summary is machine-generated.Researchers identified three smoker groups in Singapore: those who smoke at work, outside the home, or everywhere. Findings support targeted interventions to reduce secondhand smoke (SHS) exposure and aid smoking cessation.
Area Of Science
- Public Health
- Behavioral Science
- Epidemiology
Background
- Secondhand smoke (SHS) exposure is a significant health risk.
- Understanding where smokers choose to smoke is crucial for effective public health interventions.
- Limited research exists on smoking locations in urban, multi-ethnic Asian populations.
Purpose Of The Study
- To identify distinct classes of smokers in Singapore based on their smoking locations.
- To characterize these smoker classes using demographic and behavioral factors.
- To inform targeted strategies for smoking cessation and SHS exposure reduction.
Main Methods
- Latent class analysis (LCA) of data from 1,546 participants in the 2021 Singapore Smokers' Survey.
- Classified smokers based on reported locations for smoking at home and outside the home.
- Multinomial logistic regression used to analyze predictors of class membership.
Main Results
- Three distinct smoker classes were identified: 'smoke at work' (75.7%), 'smoke outside home' (14.0%), and 'smoke everywhere' (10.2%).
- Significant predictors of class membership included ethnicity, housing type, marital status, hardcore smoking status, and family norms.
- Smokers in the 'smoke everywhere' class were more likely to be Malay, hardcore smokers, and to smoke their first cigarette within 30 minutes of waking.
Conclusions
- The heterogeneity in smoking locations supports tailored interventions for smoking cessation and SHS protection.
- Culturally sensitive interventions addressing social norms, familial influence, and environmental factors are recommended.
- Targeted strategies could focus on workplace smoking, promoting smoke-free homes, and intensive interventions for high-risk groups.

Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:
Descriptive Statistics: These provide basic...
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...
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...
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume.
Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...
