Brief summary

This study evaluates adherence to a personalized prevention plan in female night shift workers at increased risk of breast cancer. Night shift work is associated with circadian disruption and increased cancer risk, as well as cardiovascular and reproductive health risks. Participants attend an initial consultation including clinical assessment and development of a personalized prevention plan targeting modifiable risk factors such as alcohol consumption, physical activity, smoking, diet, and weight. Follow-up is conducted remotely over 5 years to assess adherence to recommendations and screening. Participant satisfaction and adherence to additional consultations are also evaluated.

Detailed description

Breast cancer is the most common cancer among women, and prognosis depends on early detection. Night shift work is associated with circadian rhythm disruption and increased cancer risk. This single-center interventional study evaluates adherence to a personalized prevention plan (PPP) developed during an initial consultation. This consultation includes a review of medical history, a lifestyle assessment, and a physical examination. The PPP targets modifiable risk factors, including smoking, alcohol consumption, diet, physical activity, and weight. Participants are followed for 5 years, with assessments at 1, 2, 3, and 5 years. Adherence is defined as the implementation of at least one recommendation or the completion of prescribed screening tests. Secondary objectives include assessing satisfaction with and adherence to cardiology and fertility consultations when recommended.

Design outcomes

Primary

MeasureTime frameDescription
Adherence to Personalized Prevention Plan established during the initial risk assessment consultationAt 1, 2, 3 and 5 years.Proportion of participants adhering to at least one recommendation of the Personalized Prevention Plan or completing prescribed screening. Percentage of participants who lost weight when overweight had been identified during the initial consultation. Percentage of participants with modified sporting activity according to the recommendations at the initial consultation. Percentage of participants who had quit smoking. Percentage of participants who modified their alcohol consumption when it was excessive at the initial consultation. Percentage of participants who changed their diets when a dietary imbalance was observed during the initial consultation. Percentage of women who underwent screening as recommended following the initial consultation.

Secondary

MeasureTime frameDescription
Overal patient satisfactionAt 1, 2, 3 and 5 yearsPatient satisfaction regarding the PPP will be assessed 1 year following the intervention using the validated "Patient Satisfaction Questionnaire Short Form (PSQ-18)", based on a 5-point Likert scale ranging from "strongly disagree" to "strongly agree"
Participant satisfaction with the adapted consultation to night workAt 1, 2, 3 and 5 years.Satisfaction rate of women with the consultation system adapted to night. Patient satisfaction will be assessed using the validated "Patient Satisfaction Questionnaire Short Form (PSQ-18)", based on a 5-point Likert scale ranging from "strongly disagree" to "strongly agree".
Screening adherence to a cardiovascular consultation recommendationAt 1, 2, 3 and 5 years.Proportion of participants who had the consultation with a cardiologist when recommended
Screening adherence to a fertility consultation consultation recommendationAt 1, 2, 3 and 5 years.Proportion of participants who had the consultation with a cardiologist when recommended
