Parent‐reported indicators for detecting feeding and swallowing difficulties and undernutrition in preschool‐aged children with cerebral palsy

Aim To determine the most accurate parent‐reported indicators for detecting (1) feeding/swallowing difficulties and (2) undernutrition in preschool‐aged children with cerebral palsy (CP). Method This was a longitudinal, population‐based study, involving 179 children with CP, aged 18 to 60 months (mean 34.1mo [SD 11.9] at entry, 111 males, 68 females [Gross Motor Function Classification System level I, 84; II, 23; III, 28; IV, 18; V, 26], 423 data points). Feeding/swallowing difficulties were determined by the Dysphagia Disorders Survey and 16 signs suggestive of pharyngeal phase impairment. Undernutrition was indicated by height–weight and skinfold composite z‐scores less than −2. Primary parent‐reported indicators included mealtime duration, mealtime stress, concern about growth, and respiratory problems. Other indicators were derived from a parent feeding questionnaire, including ‘significant difficulty eating and drinking’. Data were analysed using multilevel mixed‐effects regression and diagnostic statistics. Results Primary parent‐reported indicators associated with feeding/swallowing were ‘moderate–severe parent stress’ (odds ratio [OR]=3.2 [95% confidence interval {CI} 1.3–7.8]; p
