Pharmacist Led Nutritional Counselling as a Community Intervention for Obesity, Undernutrition, and Anaemia: Evidence from a 1135 Participant Prospective Interventional Study in India

ObjectivesTo examine the pattern, magnitude, and demographic distribution of measurable improvements across five outcome parameters following three monthly pharmacist led nutritional counselling sessions delivered to community dwelling participants in semi urban India. DesignSecondary analysis of interventional follow up data from a prospective community based study. SettingSchools and colleges in Narasaraopeta, Andhra Pradesh, India, from September 2021 to March 2022. ParticipantsOf 1,200 participants assessed at baseline, 1,135 (94.6%) completed at least one counselling session and formed the analysis cohort. The age range was 10 to 60 years. The majority of participants, 92.4%, were aged between 11 and 20 years. All 1,135 were anaemic at baseline. InterventionsThree structured monthly counselling sessions were delivered by pharmacy students under qualified faculty pharmacist supervision. Each session included individualised dietary guidance, lifestyle modification advice, and culturally adapted written health education materials. Primary and secondary outcome measuresCumulative proportion of participants achieving measurable improvement in body mass index (BMI), waist circumference (WC), hip circumference (HC), waist to hip ratio (WHR), and haemoglobin (Hb) concentration at each session, stratified by age group and sex. ResultsAll five parameters showed progressive cumulative improvement across sessions. By session three, 44 participants (3.6%) showed improved BMI, 39 (3.25%) achieved reduced WC, 34 (2.8%) reduced HC, 33 (2.75%) improved WHR, and 115 (9.5%) demonstrated improved Hb. Adolescents aged 11 to 20 years were consistently the most responsive subgroup. Haemoglobin showed the steepest improvement trajectory, rising from 1.75% at session one to 9.5% at session three, representing a 5.4 fold increase achieved through dietary counselling alone without pharmacological supplementation. ConclusionsThree monthly pharmacist led nutritional counselling sessions produce measurable and progressive improvements in both anthropometric and haematological outcomes in community settings. Adolescents are the most responsive population. These findings support the integration of pharmacists into community non communicable disease prevention programmes in India and provide a replicable low resource model applicable to comparable global settings. Strengths and limitations of this studyThis secondary analysis provides the first independent quantification of pharmacist led counselling effectiveness across five simultaneous nutritional outcome parameters in a large South Asian community cohort of 1,135 participants. The intervention model of three structured monthly sessions is replicable, low cost, and does not require pharmacological supplementation, which strengthens its applicability to resource limited settings across the world. The source data record whether any positive change occurred at each session rather than the magnitude of individual change, which means formal effect size calculation is not possible and direct comparison with randomised trial evidence is limited. The absence of a concurrent control group means that maturation effects, which are particularly relevant in the adolescent dominant cohort, cannot be fully excluded as a contributing factor. All data originate from a single semi urban Indian setting, and whether these findings extend to UK South Asian diaspora populations or other contexts requires dedicated further investigation.
