The community pharmacist has significant potential to assist in providing health advice aimed at the improvement outcomes pertaining to weight management, however, up to now, evidence regarding its effectiveness has been inconclusive. In Thailand, community pharmacy involvement in weight management is a novel idea and therefore needs an evaluation of its effectiveness.
To examine essential outcomes, comparing the pharmacist's interventions with a routine weight management service provided at a primary care unit (PCU).
Maha Sarakham province, Thailand.
A randomized controlled trial was designed involving sixty-six obese patients randomly assigned to either the control group or the experimental group. Participants in the control group received group counselling from the PCU staff as usual, while those participants in the experimental group received one-on-one advice from a community pharmacist along with the weight loss handbook for self-study. Both groups were followed up and clinical outcomes were monitored four times at weeks 0, 4, 8, and 16. Eating behaviours and knowledge about overweight and obesity were measured twice, at weeks 0 and 16.
Clinical outcomes included weight, waist circumference, body mass index, measured by standard medical devices. Eating behaviours were measured by the theory of planned behaviour (TPB) questionnaire. Knowledge was measured by a questionnaire focusing on the subjects' level of understanding regarding overweight and obesity issues.
Neither group showed improvement in clinical outcomes. The TPB average sum score significantly increased from baseline in the experimental group in terms of intention to perform healthy dieting behaviour, subjective norm, behavioural beliefs, normative beliefs, and control beliefs. (P < 0.05) In the control group, scores increased significantly from the baseline only for behavioural beliefs. (P < 0.05) Moreover, the knowledge score in experimental group increased significantly from 6.42 ± 1.94 to 8.75 ± 0.68 (P < 0.05).
Thai community pharmacists can help to improve both eating behaviour and knowledge about weight and obesity among obese patients. However, since the effect on clinical outcomes is unclear, a long-term study is still needed.
社区药剂师在提供旨在改善体重管理相关结果的健康建议方面具有巨大潜力,但到目前为止,其有效性的证据尚无定论。在泰国,社区药房参与体重管理是一个新的想法,因此需要对其效果进行评估。
检查主要结果,比较药剂师的干预措施与初级保健单位(PCU)提供的常规体重管理服务。

设计了一项随机对照试验,涉及 66 名肥胖患者,随机分为对照组和实验组。对照组患者接受 PCU 工作人员的小组咨询,而实验组患者则接受社区药剂师的一对一咨询,并提供减肥手册进行自学。两组均进行随访,在第 0、4、8 和 16 周监测临床结果。在第 0 和 16 周两次测量超重和肥胖的饮食行为和知识。
临床结果包括体重、腰围、身体质量指数,由标准医疗设备测量。饮食行为通过计划行为理论(TPB)问卷测量。知识通过专注于超重和肥胖问题的主题理解水平的问卷进行测量。
两组临床结果均无改善。实验组 TPB 平均总分在健康节食行为意向、主观规范、行为信念、规范信念和控制信念方面均从基线显著增加。(P<0.05)在对照组,仅行为信念的分数从基线显著增加。(P<0.05)此外,实验组的知识分数从 6.42±1.94 显著增加到 8.75±0.68(P<0.05)。
泰国社区药剂师可以帮助改善肥胖患者的饮食行为和体重与肥胖相关知识。然而,由于临床结果的影响尚不清楚,仍需要进行长期研究。
