Title: suggestion……Prevalence and Factors Associated with Loneliness Among Indonesian
Female Adolescents: A Cross-Sectional Study
Abstract:
Please revise the first sentence,..adolescence is a known phase of the vulnerability period.
The developmental process increases adolescents’ vulnerability and frequent experience of
loneliness.
Please use the word “prevalence” instead of rate or burden because the word prevalence refers
to population.
Before multiple logistic regression, please add descriptive analysis
Introduction:
please revise the first and second paragraphs. The authors may start with definition, prevalence
globally and in Asian countries,
The second paragraph is for factors associated with loneliness.
Why do the authors focus only on females? But in the introduction, there was a sentence that
compared males.
Methods:
Is the GSHS 2015 the most recent national survey in Indonesia?
Some of the independent variables such as Currently Smoking cigarette, Current alcohol use,
Ever drink from Alcohol, Trouble from using Alcohol, Ever use amphetamine may have
imbalance of sample size. The prevalence is very small and this problem needs to be addressed
in the methodology and limitation of the study. The authors need to address how the independent
variables are selected for the model and must check whether the group comparison is adequate
in terms of the sample size of two proportions. Please also check that a very wide confidence
interval in Table 2 for each independent variable.
The details of study populations, sample size, sampling method can be found at the WHO
website…..this sentence refers to the sample size for the prevalence study. But, the author of
this article is determining the factors associated with loneliness where the appropriate sample
size was not explained on the website. The authors must consider two proportions of sample size
for each independent variable. The inadequate sample may cause a suppression effect or errors
in multivariable logistic regression. On the other hand, the authors must explain confounding
factors, interaction, multicollinearity and model fitness in the methods section.
Please explain whether the complex design was used during data analysis and whether weightage
was calculated.?
Please explain whether binary logistic regression or complex sample logistic regression was
used in this study?
Result:
Please standardize decimal points in the text and also in the table. Please report the model fitness
below Table 2. Please adhere to the guideline for preparing a table in the manuscript.
Discussion:
6.5% is considered low? Are you sure?.. any prevalence above 5% is regarded as a significant
public health problem..
Please connect the first para and second paragraph in the discussion.
More research on the cause and effect of hunger and loneliness in adolescent populations is
important. … I agree with this sentence because it may have an indirect effect that starts with
poor socioeconomic status.
Conclusion:
Please do not highlight the word low in conclusion. 6.5 % is not low in terms of public health
significance, but I agree with this sentence …… Generally, we show in this study that loneliness
exists among Indonesian female adolescents and that Government should sensitize the public
about associated factors to manage it and prevent its spread.
