3 Key Observations
Observation 1
According to the results, Arab individuals' HRQoL suffers when they are overweight. The
ORWELL 97 questionnaire was used to measure HRQoL in this research of 129 obese people
who were actively seeking therapy. These people were referred to Beirut Arab University (BAU)
at Lebanon's Nutritional and Weight Management Outpatient Clinic. One hundred and thirty
volunteers of the same age and gender who were not overweight served as a control group.
Results demonstrated that those with obesity, regardless of gender, had poorer HRQoL levels
compared to lean individuals and healthy controls. Conclusion Obesity has a major detrimental
effect on HRQoL, as shown by our results.
Observation 2
Only among female individuals who were obese was there a correlation discovered
between an increase in ORWELL 97 scores and a higher body mass index (BMI). This
association was only detected in the female participants. An increase of one unit in BMI was
shown to increase the probabilities of receiving an ORWELL 97 score suggestive of clinically
substantial deterioration of HRQoL by about 23 percent, according to the findings of the study
using linear regression. The results indicate that weight management programs with the goal of
lowering BMI may assist to enhance HRQoL in obese female adults.
Observation 3
The study draws attention to the dearth of research on HRQoL and obesity in nations
where Arabic is the primary language. This is particularly true in the nations that make up the
2
Gulf Cooperation Council, where the obesity rate has been steadily climbing over the last
decade. The few known studies that have evaluated HRQoL in obesity in Arab adults have relied
on weight-related HRQoL questionnaires that are not particular to the population being studied.
It is well recognized that these surveys are incapable of providing an appropriate assessment of
the effect that obesity has on one's quality of life. This study adds to the expanding body of
information on the effect that obesity has on HRQoL in Arab adults and sheds light on the need
for more research in this particular field.
2 Statistics
The β statistic and the odds ratio are both derived from the research and may be debated.
(OR). In linear regression analysis, the measure of the connection between two variables is
denoted by the symbol β. A linear regression analysis was carried out with the purpose of
determining the relationship between ORWELL 97 scores and body mass index (BMI) for
individuals who were obese in this research. According to the β value of 2.89, it seems that an
increase of one unit in ORWELL 97 scores is connected with a one-unit rise in BMI among
female participants who were classified as having obesity. The confidence interval (CI) for the β
value is 1.43 to 4.53, which indicates that there is a substantial positive correlation between BMI
and ORWELL 97 scores among female participants who are obese. The participants were from a
research study. On the other hand, the β value for the male participants did not show any
significant differences. This would imply that there is no significant connection between
ORWELL 97 scores and BMI among obese male participants in the study. This conclusion
demonstrates how crucial it is to take into account disparities between the sexes when
investigating the effects of obesity on HRQoL.

In the field of logistic regression analysis, a measure of the relationship between two
variables is referred to as the odds ratio (OR). A logistic regression analysis was carried out for
the purpose of determining the probability of receiving an ORWELL 97 score in this research.
With a one-unit rise in BMI, this score was predictive of a clinically significant decline in
HRQoL ( 71.75), indicating a clinically significant impairment. According to the odds ratio of
1.23, the probability of having an ORWELL 97 score lower than 71.75 rises by about 23% for
every unit that the subject's body mass index (BMI) rises. The OR value has a 95% confidence
interval ranging from 1.09 to 1.40. This score suggests that there is a statistically significant
correlation between body mass index (BMI) and the likelihood of having an ORWELL 97 score,
which is suggestive of a clinically significant reduction in HRQoL. The detrimental effects that
obesity has on HRQoL are highlighted by this research. It also underscores the necessity for
doctors to urge patients who are obese to begin weight-loss programs and to continue with them
even after they get discouraged.
1 Remaining Question
One remaining question that can be asked after exploring regression in practice using the
given article is whether there are other variables or factors that could affect the HRQoL of
individuals with obesity, aside from BMI. While the article provides evidence that a higher BMI
is associated with lower HRQoL among female participants with obesity, it is possible that other
factors, such as age, socioeconomic status, or presence of comorbidities, could also impact
HRQoL. Further studies could investigate these potential confounding variables to gain a more
comprehensive understanding of the relationship between obesity and HRQoL.
