Meta-Analysis on Work Strain and Obesity Risks

The paper focuses on the meta-analysis on the relationship of the straining in jobs and the obesity. The job strain influences the intense of the risk of obesity. The results provided the odds ratio as 1.00 with little heterogeneity and other case did not show the relationship between the job strain and weights.

Introduction
The paper focuses on the meta-analysis on the relationship of the straining in jobs and the obesity.
The obesity or over weight is measured with the help of the job strain. There are various factors,
which influence the job strain that relates to the risk of the obesity. The paper considered the review
of the article titled “Job strain and risk of obesity: systematic review and meta-analysis of cohort
studies.” According to this paper, the job strain influences the intense of the risk of obesity. As per
the paper, the risk factors such as coronary heart disease, type 2 diabetes, and stroke are occurring
due to the risk of obesity.
The topic is appropriate and relates the job strain to the risk in over weights or obesity. The job
strain and risk of obesity are related to each other. By adopting the topic, the straining in jobs and
the over weights or obesity are analyzed in the research using certain standards.
Steps
The data sources and searches are very important for the analysis. The steps involved in the meta-
analysis are given as follows:
 Data sources and searches
 Inclusion criteria
 Synthesis of data
 Statistical analysis
Data sources and searches
The paper adopted the standards of PRISMA guidelines. The literature search consists of “all fields”
sourced from the online sources such as Embase and PubMed. The search terms involved in the
research are stress, job strain, demands, control, workload, psychosocial, body mass index (Hebden
L, et.al, 2012).
Criteria Included
 Exposures at individual levels
 Data at the outcome or results
 Impacts of strain
 Outcome: Weight gain or Obesity
These criteria are considered in the research and the research provides more focus on the
theoretical models. The statistical inferences are interpreted through the odds ratios, estimates in
risks and hazard ratios at the confidence levels of 95% (Johansson K, et.al, 2014).
Synthesis of data
The meta-analysis was conducted for the study that helps to provide results with odd ratios. The
model synthesized with the age, sex, socioeconomic status as covariates. The model considers these
associations of job strains, obesity, and adjustments with the variables such as sex, age, and
socioeconomic status. The study leads to the associations in the increase and decrease in job strain
with the changes in obesity or over weights (M Kivimäki, et.al, 2015).

Meta-analysis was conducted to analyse the studies for the estimates. The relationship between the
job strain and obesity are analysed individually. The study was conducted with the consideration of
the published
The study considered the 3579 results with the appropriate studies of five papers with the included
criteria. Eight independent studies are sourced from the five papers that are added in the meta-
analysis.
Results
The results clearly denote the lack of interrelationship between the job straining and overweight or
obesity. The increased strains in job related to increase in the risk of obesity and the decrease in job
strain is not linked to decrease in the risk of obesity. The longitudinal findings in the results provided
inconsistency with the relationship of the strains in the job and obesity risks (Nyberg ST, et.al , 2012).
Studies:
Eight studies are utilized in the five papers for the meta-analysis in the research about the
relationship of the factors associated to the job strain and obesity risks.
N:
N is the total samples who are involved in the research study for the analysis of the relationship of
job strain with that of the obesity. As per the research, total N is 42,222.
Test Statistic Calculation:
As per the paper, the statistic calculation is based on the fixed effect analysis using l2 statistics.

Significance of results:
The results provided the odds ratio as 1.00 with little heterogeneity and other case did not show the
relationship between the job strain and weights. The increase in job strain has associated to the
increase in weights and obesity.
Moderators:
No moderators involved in the research as the factors associated show the inconsistency in the
relationship. The moderators in the research not involved.
Artefact corrections:
The study shows artefacts and inconsistency in the research. The artefacts included in the research
can be corrected in terms by the determination of the specific potential differences in response
characteristics during straining and observation of the unhealthy eating with stress that may result
to the increased obesity. However, there requires new factors for the research.
Implications of the results:
The results from the overall analysis lead to the fact that there is no relationship between the
straining in jobs and the obesity as the inconsistencies are present in the study.
Interpretation of results in an organizational setting
The results in the organizational setting are provided the results that have no association between
the strain in works and over weights. The interpretation is clear which specifies there is no linkage
between the work strain and over weights or obesity. However, results provide that the increase in
job strain and increase in obesity are included. Within the organizational setting, the job strain and
obesity can be measured. Apart from these, the other factors are also included with the analysis. The
study is suitable to measure in organizational settings.
