Nutritional Impact of Workplace Wellness Program: A Bank Branch Case Study

Thesis Abstract

This study investigates the nutritional impact of a structured workplace wellness program implemented at a mid-sized commercial bank branch, addressing the rising incidence of suboptimal dietary behaviors and related health risks among urban banking employees. The problem centers on how corporate wellness initiatives in high-stress, sedentary work environments influence employees’ dietary patterns, nutrient intake, and related metabolic risk markers. The aim is to evaluate the effectiveness of the program in improving dietary quality and to elucidate the mechanisms through which wellness interventions translate into nutritional outcomes. Specific objectives are (1) to assess changes in dietary intake and adherence to dietary guidelines over a 12-month period; (2) to examine shifts in anthropometric measures (body weight, body mass index, waist circumference) and selected cardiometabolic biomarkers (fasting glucose, lipid profile) pre- and post-intervention; (3) to identify behavioral determinants (knowledge, self-efficacy, and motivation) mediating dietary change using the Health Belief Model and Self-Determination Theory; (4) to evaluate employee engagement with program components (nutrition coaching, on-site healthy meals, and educational materials) and their association with nutritional outcomes; and (5) to compare outcomes across departments with varying shift patterns and job stress levels. The study adopts a mixed-methods design, combining a quasi-experimental, non-randomized pretest–posttest framework with qualitative explorations to contextualize quantitative findings. The population comprises all full-time employees at the branch (N ? 320). A stratified random sample of 240 employees will be invited to participate, with 200 completing baseline and 12-month follow-up assessments to allow for attrition. Quantitative data will be collected through validated dietary intake instruments (multiple-pass 24-hour recalls conducted on three non-consecutive days, including weekend intake), a standardized dietary quality index, anthropometrics, and fasting blood samples analyzed for glucose, total cholesterol, HDL, LDL, and triglycerides. Psychosocial constructs will be measured using validated scales for nutrition-related knowledge, self-efficacy, motivation (intrinsic/extrinsic), and perceived barriers. The on-site wellness program components will be documented via attendance records and program fidelity checklists. Quantitative analyses will include descriptive statistics, paired t-tests and repeated-measures ANOVA to detect within-subject changes, and ANCOVA to adjust for confounders (age, sex, baseline BMI). Regression analyses will test associations between engagement in program components and nutritional outcomes. Mediation analyses will explore whether changes in knowledge, self-efficacy, and motivation mediate the relationship between program exposure and dietary quality. A mixed-methods integration will use a convergent design, with qualitative data collected from semi-structured interviews and focus groups (n ? 30) of participants and program staff to capture experiences, perceived facilitators and barriers, and contextual factors. The qualitative data will be analyzed thematically using NVivo, employing an inductive-deductive approach, and integrated with quantitative results to interpret divergent and corroborative findings. Expected findings anticipate improvements in dietary quality scores, reductions in total caloric intake from ultra-processed foods, and modest reductions in weight and waist circumference among high-engagement employees. Biomarkers are expected to show favorable trends (lower fasting glucose and improved lipid profiles) in those with sustained dietary improvements. The study is anticipated to reveal that higher attendance at nutrition coaching, consistent access to healthier meals, and ongoing educational messaging correlate with more pronounced nutritional gains, with motivational constructs mediating these effects. The contribution to knowledge includes empirical evidence on the nutritional impact of workplace wellness programs within the banking sector, a nuanced understanding of engagement processes, and practical insights into designing scalable, fidelity-driven interventions that consider shift-work constraints and stress-related eating patterns. The main conclusion is that well-structured, theory-informed workplace nutrition interventions can measurably improve dietary quality and selected cardiometabolic risk factors in a bank branch setting, particularly when coupled with personalized coaching and accessible healthy options. Recommendations include adopting standardized program fidelity protocols, enabling flexible coaching schedules to accommodate shift workers, integrating micro-learning modules into the workday, and ensuring continuous evaluation using combined quantitative and qualitative metrics to inform iterative improvements.
