Abstract

Introduction:

Recent literature has demonstrated individuals may be using electronic cigarettes (e-cigarettes) as a method of weight loss and/or management. Furthermore, e-cigarette companies are developing and patenting technologies related to e-cigarettes and weight loss. This study aims to determine the association between intentions to lose weight and e-cigarette use behaviors among a nationally representative sample of high school students.

Methods:

Data were obtained from the 2015 Youth Risk Behavior Surveillance survey. Participants were 12 847 students in grades 9-12 in the United States. Multivariate multinomial logistic regression models assessed the association between past 30-day e-cigarette use and weight loss intentions among 9-12 grade students. Subsample analyses were conducted, stratified by sex. Covariates included perceived weight, sex, race/ethnicity, grade, and past 30-day tobacco use.

Results:

Overall, 23.7% of the sample used e-cigarettes in the past 30 days. E-cigarette use was associated with 1.38 (95% CI = 1.07% to 1.78%) greater risk of intentions to lose weight among the full sample, controlling for covariates. Among girls, e-cigarette use was associated with 1.44 (95% CI = 1.05% to 1.97%) greater risk of intentions to lose weight, controlling for covariates. Among boys, e-cigarette use was associated with 1.40 (95% CI = 1.04% to 1.88%) greater odds of intentions to gain weight, controlling for covariates.

Conclusion:

Findings show a significant association between e-cigarette use and intentions to lose weight among high school students, among the full sample. Interestingly, e-cigarette use was statistically associated with intentions to gain weight among boys. Longitudinal study is needed to further examine this relationship.

Implications And Contribution:

This is the one of the first studies reporting on e-cigarette use and weight loss intentions among adolescents, both highly prevalent among this population. These findings are an important development in the study of e-cigarette use given the established link between conventional cigarette smoking and weight loss and/or management.

Student t Distribution

Student t Distribution

The population standard deviation is rarely known in many day-to-day examples of statistics. When the sample sizes are large, it is easy to estimate the population standard deviation using a confidence interval, which provides results close enough to the original value. However, statisticians ran into problems when the sample size was small. A small sample size caused inaccuracies in the confidence interval.
The Student t distribution was developed by William S. Goset (1876–1937) of the...

Microsoft Excel: Student's t-Test

Student's t-test in Microsoft Excel is a statistical method used to compare the means of two groups to determine if they are significantly different from each other. It's commonly used to evaluate hypotheses, such as testing whether a treatment has an effect compared to a control group. Excel provides built-in functions to perform t-tests, making it accessible for users needing to conduct basic statistical analysis.
To conduct a t-test in Excel, use the T.TEST function or the "Data...

Weighted Mean

Weighted Mean

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Comparing Experimental Results: Student's t-Test

The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

Atomic Weight

Atomic Weight

Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...

Mass and Weight

Mass and Weight

Mass and weight are often used interchangeably in everyday conversation. For example, medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...
