Ouick weight loss linked to lowered CKD risk among men with NAFLD: Study
CHINA: According to a study published in the journal Obesity, patients with obesity and high blood pressure may experience a lower risk of developing chronic kidney disease (CKD) with a short-term weight loss of at least 7% of body weight.
According to reports, 20–30% of adults have non-alcoholic fatty liver disease (NAFLD), which is often associated with other metabolic conditions. NAFLD has been associated with chronic kidney disease (CKD), which has a high incidence rate, high rates of morbidity and mortality, and significant medical expenses. Some metabolic risk factors that are also metabolic comorbidities of NAFLD are linked to CKD.
The purpose of the study was to investigate the relationship between obesity and chronic kidney disease (CKD) following the development of nonalcoholic fatty liver disease (NAFLD).
The link between obesity and chronic kidney disease (CKD) after the emergence of non-alcoholic fatty liver disease (NAFLD) was investigated in this prospective cohort research of 10,311 adult Chinese men. In order to examine advanced CKD risk in NAFLD with various baselines or trajectories in obesity measurements, the Fine-Gray model was used.
Key highlights of the study:
- Subjects who had obesity but did not have obesity on a subsequent BMI measurement in a subset of the cohort having access to a second BMI measurement had a considerably lower risk of developing CKD than those who had constant obesity (adjusted HR, 0.62).
- The incidence rates of CKD were the same in the groups with and without obesity (BMI, 25) during the course of a median follow-up of 10.1 years following NAFLD diagnosis (6.39 and 5.81 per 1000 person-years, respectively).
- A decreased risk for CKD was observed in NAFLD patients with a weight reduction of at least 10% (HR = 0.58) and 7.0% to 9.9% (HR = 0.53) compared to those with a weight change of less than 4.9%.
- Patients with high blood pressure were the only ones who had a decreased risk of losing less than 7% of their body weight when compared to people who were of stable weight (adjusted HR = 0.48).
The authors concluded that in males with NAFLD, losing weight may prevent the development of CKD. For the management of NAFLD, it's critical to track weight, waist-hip ratio, and circumference measurements. However, future research in other demographics is required, they added.
