Abstract

Aim

Obesity is a significant global health challenge and a modifiable and preventable risk factor for several medical conditions. This study aimed to assess zinc levels in patients with morbid obesity undergoing bariatric surgery (BS) and to determine the correlation between zinc deficiency and morbid obesity.

Methods

A prospective cross-sectional study was conducted at Dr. Sulaiman Al Habib Hospital-Olaya Branch, a tertiary referral center for BS, over a 12-month period from June 2024 to June 2025. The study population comprised 217 patients (aged ≥ 15 years) diagnosed with obesity who were scheduled to undergo BS. Zinc deficiency was defined as a serum zinc level of < 68 µg/dL.

Results

It was observed that among 217 participants, 32.3% (n = 70) were zinc deficient, of which 27.2 and 35.3% were noticed to have zinc deficiency in males and females, respectively. The mean zinc levels were 79.12 ± 15.91 and 73.32 ± 12.21 µg/dL in males and females, respectively (p = 0.003). Serum zinc showed positive correlations with height (r = 0.159, p = 0.02) and hemoglobin (r = 0.231, p < 0.001), but not with age, weight, or BMI. Among patients with zinc deficiency (n = 13), hypertension was the most common (61.5%), followed by diabetes (23.1%) and combined diabetes with hypertension (15.4%).

Conclusion

Patients with morbid obesity are at high risk for zinc deficiency. Routine preoperative zinc screening should be incorporated into standard care to enable timely interventions and improve long-term nutritional health.

计划进行减肥手术的病态肥胖患者术前血清锌水平：一项横断面研究。

目的：肥胖是一项重大的全球健康挑战，也是几种医疗条件下可改变和可预防的风险因素。本研究旨在评估接受减肥手术（BS）的病态肥胖患者的锌水平，并确定锌缺乏与病态肥胖之间的相关性。方法：一项前瞻性横断面研究在Dr. Sulaiman Al Habib医院- olaya分院（BS三级转诊中心）进行，研究时间为2024年6月至2025年6月，为期12个月。研究人群包括217名确诊为肥胖的患者（年龄≥15岁），他们计划接受BS治疗。结果：在217名参与者中，32.3% （n = 70）的人缺锌，其中27.2%的男性缺锌，35.3%的女性缺锌。男性和女性的平均锌水平分别为79.12 ± 15.91和73.32 ± 12.21 µg/dL （p = 0.003）。血清锌与身高（r = 0.159,p = 0.02）、血红蛋白（r = 0.231,p ）呈正相关（r = 0.159,p ）。常规术前锌筛查应纳入标准护理，以便及时干预和改善长期营养健康。

期刊介绍： The aim of Obesity Research & Clinical Practice (ORCP) is to publish high quality clinical and basic research relating to the epidemiology, mechanism, complications and treatment of obesity and the complication of obesity. Studies relating to the Asia Oceania region are particularly welcome, given the increasing burden of obesity in Asia Pacific, compounded by specific regional population-based and genetic issues, and the devastating personal and economic consequences. The journal aims to expose health care practitioners, clinical researchers, basic scientists, epidemiologists, and public health officials in the region to all areas of obesity research and practice. In addition to original research the ORCP publishes reviews, patient reports, short communications, and letters to the editor (including comments on published papers). The proceedings and abstracts of the Annual Meeting of the Asia Oceania Association for the Study of Obesity is published as a supplement each year.
