Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To explore the application effect of personalized lateral decubitus pillow for patients with cervical spine surgery. Methods A totals of 106 patients after cervical spine surgery were recruited and randomly divided into control group (48 cases) and experimental group (58 cases). Patients in the control group used the common pillow when patients lay lateral position-the height of pillow equal to shoulder cheekbone breadth, while experimental group used the personalized lateral decubitus pillow which supported suspended occipitalis and the height of pillow adjusted by individual. The comfort score, incision pain score and last time for lateral position of all patients were compared. Results The comfort score of the experimental group was significantly higher than that of the control group during the first day, second day and the third day after surgery [(66. 3 ± 4. 8) vs (63. 4 ± 3. 5), (68. 4 ± 5. 3) vs (65. 1 ± 4. 6), (71. 3 ± 4. 8) vs (68. 3 ± 4. 4);t=3. 461,3. 473,3. 270, respectively; P <0. 05]. The incision pain score of the experimental group was significantly lower than that of the control group during the first day, second day and the third day after surgery [(5.09±1.33) vs(5.88±1.29),(4.78±1.30) vs(5.52±1.09),(4.33±1.13) vs(5.06±1.06);t=3. 127,3. 157,3. 427, respectively;P<0. 05]. The last time of the experimental group for lateral position were longer than that of control group [(88. 6 ± 15. 2) min vs (79. 3 ± 14. 1) min; t = -3. 239,P =0. 002]. Conclusions It can increase the comfort score, extend the last time for lateral position and lessen incision pain to use the individuation lateral position pillow for patients after cervical spine surgery.
