Study summary

This study aims to evaluate body weight status, lifestyle patterns, and cardiometabolic risk in women in remission from breast cancer undergoing adjuvant hormone therapy, and to assess the effects of a structured nutritional intervention based on the Mediterranean diet combined with physical activity promotion.

A total of 150 women treated with adjuvant hormone therapy are recruited from the oncology department of Akid Othmane Hospital in Oran, Algeria. Participants include women receiving tamoxifen or aromatase inhibitors. Baseline assessments include anthropometric measurements (body weight, body mass index, waist and hip circumferences), socioeconomic characteristics, and lifestyle evaluation.

Dietary intake is assessed using 24-hour dietary recalls and 3-day food records. Total energy intake, macronutrient and micronutrient composition, dietary habits, meal distribution, and adherence to the Mediterranean diet (MEDAS score) are evaluated. Physical activity level, sedentary behavior, daily energy expenditure, and energy balance are also determined.

Cardiometabolic risk is assessed through measurement of blood pressure, fasting blood glucose, lipid profile (total cholesterol, LDL-C, HDL-C, triglycerides), uric acid, albumin, creatinine, urea, and calculation of atherogenic ratios.

A structured educational program promoting adherence to the Mediterranean diet and increased physical activity is implemented. Anthropometric, dietary, lifestyle, and cardiometabolic parameters are monitored over time to evaluate changes associated with the intervention.

Read the detailed description

The objective of this interventional study is to evaluate body weight status, lifestyle characteristics, and cardiometabolic risk in women in remission from breast cancer undergoing adjuvant hormone therapy, and to assess the impact of a nutritional intervention based on the Mediterranean diet combined with physical activity promotion.

A total of 150 women treated with adjuvant hormone therapy are recruited from the oncology department of Akid Othmane Hospital in Aïn El Turc, Oran, Algeria. Participants are classified according to the type of endocrine treatment received, including tamoxifen or aromatase inhibitors.

Baseline evaluation includes anthropometric measurements such as body weight, body mass index, waist circumference, and hip circumference. Socioeconomic characteristics and lifestyle habits are documented.

Dietary assessment is conducted using 24-hour dietary recalls and 3-day food records. Nutritional analysis includes total energy intake, macronutrient and micronutrient composition, dietary quality, meal distribution, and adherence to the Mediterranean diet assessed using the MEDAS score. Food group consumption patterns and dietary behaviors are also evaluated.

Physical activity level, sedentary behavior, daily energy expenditure, and energy balance are determined using standardized assessment methods.

Cardiometabolic risk profile is evaluated through measurement of blood pressure, fasting blood glucose, lipid profile (total cholesterol, LDL-C, HDL-C, triglycerides), uric acid, albumin, creatinine, urea, and calculation of atherogenic indices.

Following baseline assessment, participants receive a structured educational program promoting adherence to the Mediterranean dietary pattern and regular physical activity. Follow-up assessments are conducted to monitor changes in anthropometric parameters, dietary habits, lifestyle behaviors, and cardiometabolic markers over time.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • confirmed hormone receptor-positive breast cancer
  • Breast cancer survivors receiving endocrine therapy (tamoxifen or aromatase inhibitors) for ≥3 months
  • No recurrence or second primary
  • Ability to perform moderate-intensity physical activity
  • Consecutively recruited during routine surveillance visits

Exclusion criteria

Exclusion Criteria:

  • Incomplete or discontinued hormone therapy
  • Concurrent ovarian suppression
  • Use of lipid-lowering medications
  • Severe uncontrolled comorbidities (e.g., diabetes, cardiac, or hepatic disease)
  • Cognitive or physical impairments preventing or participation
  • Restrictive dietary regimens
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2022 to primary completion in Feb 2025, 33 months.

Of 1,077 non-industry interventional studies with no phase under Cardiovascular Diseases, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 48. This study's 33 months is above that.

Counting every sponsor, half of 1,216 studies reached it within 26 months; a quarter within 12 and three quarters within 49.

Cardiovascular Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 2, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
