Dietitian encounters after treatment for ovarian cancer

After ovarian cancer treatment, women report health issues that may be amenable to change with dietary support. The present study investigated how many women encounter a dietitian post-treatment and the factors associated with dietitian service use.

We used data from a cohort of women with invasive epithelial ovarian cancer to identify socio-economic, clinical and personal factors associated with dietitian encounter after treatment completion. Data were collected at regular intervals using validated questionnaires up to 4 years post-treatment completion. Logistic regression (LR) and generalised linear mixed models (GLMM) were used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI) to assess factors associated with dietitian encounter at any time-point post-treatment (LR), as well as in the 3 months prior to a follow-up questionnaire (GLMM) to assess time-varying factors.

Of 819 women, 97 (12%) reported seeing a dietitian post-treatment. Factors associated with dietitian encounter were being overweight (OR_LR  = 1.7, CI = 1.1-2.8), having poorer self-rated health (OR_LR  = 2.5, CI = 1.2-5.2; OR_GLMM  = 2.3, CI = 1.2-4.4) or poorer diet quality (OR_LR  = 0.5, CI = 0.2-1.0) pre-diagnosis, treatment within the public health system (OR_GLMM  = 1.8, CI = 1.2-2.7), previous support from dietetic (OR_LR  = 3.1, CI = 1.8-5.4; OR_GLMM  = 2.8, CI = 1.8-4.2) or other allied health services (OR_LR  = 2.0, CI = 1.2-3.2; OR_GLMM  = 3.7, CI = 2.4-5.5), and having progressive disease at follow-up (OR_GLMM  = 2.2, CI = 1.4-3.3). Most women (86%) with ≥ 3 moderate-to-severe nutrition impact symptoms did not report a dietitian encounter post-treatment.

Few women encounter a dietitian post-treatment for ovarian cancer, including those with multiple nutrition impact symptoms. Further work is needed to engage those likely to benefit from dietitian support but less likely to seek or receive it.
