Cross-sectional observational study with associations only; no intervention tested, no comparator group, and findings are descriptive of perception gaps rather than causal mechanisms or treatment effects.
International Journal of Academic Excellence and Research
A descriptive cross-sectional survey of knowledge and behavioral patterns in a single demographic group; provides formative data on awareness gaps but lacks a comparator, control group, or hard clinical outcomes, and is limited to one region and one age/sex group.
Eating and Weight Disorders - Studies on Anorexia Bulimia and Obesity
A single-centre validation study of a translated psychometric instrument in a small clinical sample with acceptable internal consistency and correlational validity, but requiring larger and more diverse samples for confirmation.
A well-designed cross-sectional and longitudinal study of biomarkers in a substantial adolescent psychiatric cohort with clear measurement and modest discriminatory power, but limited by single-centre design, surrogate endpoints, and lack of clinical outcome validation.
Cross-sectional study with clear mediation findings in a defined post-surgical population; sound statistical approach but observational design and lack of clinical outcome validation limit strength.
A single-centre prospective cohort study with 50 participants showing statistically significant improvements in erectile function, genital self-image, and psychological distress after bariatric surgery, but without a control group and with acknowledged inability to establish causation.
This is a narrative review proposing a theoretical mechanism (body schema updating) for post-bariatric surgery body image disturbance, explicitly acknowledging the absence of direct empirical evidence in the target population.
Epra International Journal of Research & Development
A narrative review synthesizing evidence on eating behaviour and mental health connections, presenting multidisciplinary perspectives and recommendations for integrated interventions rather than reporting original empirical findings.
