About this study
Official title: A School-Based Anti-Inflammatory Dietary Intervention With or Without a Physical Activity Programme to Support Reproductive Health in Adolescent Girls
This study will evaluate whether a 16-week anti-inflammatory dietary intervention, delivered alone or together with a physical activity programme, can improve diet quality and support reproductive health in girls aged 14-19 years. Approximately 100 participants will be recruited from two secondary schools in Poland. Participants at both schools will receive education and practical guidance on an anti-inflammatory diet based on Mediterranean dietary principles. Participants at one school will additionally take part in a supervised physical activity programme conducted twice weekly.
The primary outcome will be the change in diet quality assessed using the KIDMED index. Additional assessments will examine menstrual health, premenstrual symptoms, menstrual pain, physical activity, body composition, anthropometric measures, selected salivary biomarkers, and the oral microbiome. Assessments will be conducted before and after the intervention.
Read the detailed description
This is a two-arm, parallel, school-based interventional study involving approximately 100 girls aged 14-19 years recruited from two secondary schools in the Greater Poland region. The intervention will last 16 weeks. Participants will not be individually randomized. Each participating school will implement one of the two intervention programmes; therefore, allocation will occur at the school level for organizational reasons.
Participants in the anti-inflammatory diet group (AIDiet) will take part in a dietary education programme based on Mediterranean dietary principles. The programme will include four practical and theoretical workshops addressing anti-inflammatory food choices and their potential relevance to reproductive health. Educational materials and tools for monitoring progress will also be available through a dedicated digital platform.
Participants in the combined intervention group (AIDiet/PAT) will receive the same dietary intervention and will additionally participate in a physical activity programme consisting of two supervised exercise sessions per week for 16 weeks. The sessions will be conducted by a physical education teacher or trainer and adapted to the participants' age and abilities.
The primary objective is to compare changes in diet quality, assessed using the KIDMED index, between the AIDiet and AIDiet/PAT groups. Secondary objectives include evaluating changes in menstrual cycle characteristics, menstrual pain, premenstrual symptoms, physical activity, anthropometric and body composition measures, selected salivary inflammatory, oxidative stress and hormonal biomarkers, and the composition and diversity of the oral microbiome.
Medical assessments, questionnaires, anthropometric and body composition measurements, and biological sample collection will be conducted before and after the intervention. The study does not include an untreated control group because all participants will receive health education intended to support reproductive health.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Mediterranean Diet Quality Index for Children and Adolescents (KIDMED) Score
Diet quality will be assessed using the 16-item Mediterranean Diet Quality Index for Children and Adolescents (KIDMED). Positively scored items receive +1 point and negatively scored items receive -1 point, giving a total score ranging from -4 to 12. Higher scores indicate better adherence to a Mediterranean dietary pattern. Change from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Secondary outcomes (10)
Change in Menstrual Pain Intensity Assessed Using a Visual Analogue Scale
Menstrual pain intensity will be assessed using a Visual Analogue Scale (VAS) ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater menstrual pain intensity. Change from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Premenstrual Symptom Severity Assessed Using the Premenstrual Symptoms Screening Tool
Premenstrual symptoms will be assessed using the Premenstrual Symptoms Screening Tool (PSST). The instrument evaluates 14 premenstrual symptoms and five areas of functional impairment. Each item is rated from 0 (not at all) to 3 (severe), giving a total score ranging from 0 to 57. Higher scores indicate greater severity of premenstrual symptoms and related functional impairment. Change from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Self-Reported Menstrual Cycle Regularity
Menstrual cycle regularity will be assessed during a medical interview based on self-reported menstrual cycle characteristics, including usual cycle length and variability in cycle length. The assessment will be performed before and after the intervention. Changes in menstrual cycle regularity from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Body Mass Index
Body weight will be measured in kilograms and height in metres. Body mass index (BMI) will be calculated as body weight divided by height squared and expressed in kilograms per square metre (kg/m²). Change in BMI from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Body Fat Percentage
Body fat percentage will be assessed using bioelectrical impedance analysis and expressed as a percentage of total body weight. Change in body fat percentage from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Fat-Free Mass
Fat-free mass will be assessed using bioelectrical impedance analysis and expressed in kilograms. Change in fat-free mass from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Waist Circumference
Waist circumference will be measured according to a standardized anthropometric procedure and expressed in centimetres. Change in waist circumference from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Systolic and Diastolic Blood Pressure
Resting systolic and diastolic blood pressure will be measured using a standardized procedure and expressed in millimetres of mercury (mmHg). Changes in systolic and diastolic blood pressure from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Acne Severity Assessed Using the Investigator's Global Assessment
Acne severity will be evaluated using the Investigator's Global Assessment (IGA). The scale provides an overall clinical assessment of acne severity, with higher grades indicating greater severity. Change in the IGA grade from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
Change in Hirsutism Severity Assessed Using the Modified Ferriman-Gallwey Score
Hirsutism severity will be assessed using the modified Ferriman-Gallwey score. Terminal hair growth in nine androgen-sensitive body areas is rated from 0 to 4, giving a total score ranging from 0 to 36. Higher scores indicate greater hirsutism severity. Change from baseline to post-intervention will be compared between the study arms.
Measured: Baseline and immediately after the 16-week intervention
