Treatment Guidelines for Adolescents with PCOS
Lifestyle interventions should be the first-line treatment for all adolescents with PCOS, with multicomponent approaches including diet, exercise, and behavioral strategies being most effective for those with excess weight. 1
Diagnostic Considerations for Adolescents
- Diagnosis of PCOS in adolescents should focus on evidence of ovulatory dysfunction and androgen excess, rather than polycystic ovary morphology 2
- Ovulatory dysfunction indicators include: consecutive menstrual intervals >90 days even in the first year after menarche; menstrual intervals persistently <21 or >45 days 2+ years after menarche; lack of menses by age 15 or 2-3 years after breast budding 2
- Androgen excess indicators include: moderate to severe hirsutism, persistent acne unresponsive to topical therapy, and persistent elevation of serum testosterone levels 2
- Adolescents with history of premature pubarche, family history of PCOS, or obesity require close surveillance 3
Lifestyle Management Recommendations
Healthy Eating Approaches
- No specific diet type has proven superior; focus on individual preferences and cultural needs while maintaining a healthy balanced diet 4
- For weight loss, aim for an energy deficit of 30% or 500-750 kcal/day (1,200-1,500 kcal/day), considering individual energy requirements 4
- Follow general healthy eating principles across the life course 4
- Avoid unduly restrictive or nutritionally unbalanced diets 4
Physical Activity Guidelines
- Recommend at least 150 minutes/week of moderate intensity physical activity or 75 minutes/week of vigorous intensity activity for prevention of weight gain 4
- Include muscle-strengthening activities on 2 non-consecutive days/week 4
- For modest weight loss, increase to at least 250 minutes/week of moderate intensity activities 4
- Both aerobic and resistance exercises have shown benefits in PCOS 4
- Minimize sedentary, screen, or sitting time 4
Behavioral Strategies
- Implement SMART (specific, measurable, achievable, realistic, timely) goal setting and self-monitoring 1, 4
- Include behavioral strategies such as goal-setting, self-monitoring, stimulus control, problem-solving, assertiveness training, slower eating, and relapse prevention 4
- Consider comprehensive behavioral or cognitive behavioral interventions to increase engagement and adherence 4
- Address psychological factors such as anxiety, depression, body image concerns, and disordered eating 1, 4
Weight Management
- Set achievable weight loss goals of 5-10% in those with excess weight, which can yield significant clinical improvements 1, 5
- Regular monitoring of weight and waist circumference is recommended 4
- Weight loss through lifestyle intervention has been shown to improve menstrual irregularities, normalize androgens, and improve cardiovascular risk factors in adolescents with PCOS 6
- Consider ethnic-specific BMI and waist circumference categories when optimizing lifestyle and weight 1, 4
- Healthy lifestyle may contribute to health and quality of life benefits even in the absence of weight loss 1
Pharmacological Management
- Combined oral contraceptives (COCs) are first-line pharmacotherapy for management of menstrual irregularity and acne 2
- Metformin is superior to COCs for weight reduction and improved dysglycemia 2
- COCs and metformin have similar effects on hirsutism, but often need to be paired with other treatment modalities for cutaneous symptoms 2
- Metformin in addition to lifestyle modification is likely to improve menstrual cyclicity and hyperandrogenism in girls with PCOS and type 2 diabetes 1
- Oral contraceptive pills for treatment of PCOS are not contraindicated for girls with type 2 diabetes 1
Multidisciplinary Approach
- A multidisciplinary model of care with dietitian, health psychologist, gynecologist, and endocrinologist has shown enhanced weight loss outcomes in adolescents with PCOS 1
- Health professional interactions should be respectful, patient-centered, and considerate of individual preferences and cultural differences 1, 4
- Screen for psychological comorbidities including anxiety, depression, body image concerns, and disordered eating 1, 2
- Regular follow-up is essential for monitoring progress and adjusting treatment plans 1
Important Considerations and Pitfalls
- Deferring a definitive diagnosis while providing symptom treatment and regular follow-up is a recommended option 2
- Treatment may decrease risk of future comorbidity even in the absence of a definitive diagnosis 2
- Screen appropriately for metabolic comorbidities associated with PCOS 2
- Avoid focusing solely on weight loss without addressing psychological aspects of PCOS 1, 4
- Be aware that ethnic groups with PCOS who are at high cardiometabolic risk require greater consideration for lifestyle intervention 1, 4
