Factors That Influence Adherence to Calcium Recommendations

Abstract

To identify barriers to following calcium recommendations among women with reduced bone mineral density (BMD), four focus group sessions were held with 30 postmenopausal women diagnosed with low BMD. Key concepts and themes were derived from transcripts. Participants were aware of the importance of calcium to their bone health, and were attempting to follow calcium intake recommendations. Several major themes associated with the ability to obtain adequate calcium were identified, including knowledge and confidence in actions, lifestyle and food preferences, and side effects and conflict with other health conditions. Participants reported that they obtained information in an effort to make a confident decision about calcium intake, but were easily confused by conflicting information. Daily routines and family and personal food preferences influenced dietary behaviours. Women indicated that side effects, particularly those associated with perceived lactose intolerance, caused them to restrict their calcium intake. Our data provide important insight into factors that women believe affect their ability to reach recommended calcium intakes. To optimize osteoporosis prevention and treatment, dietitians should focus on individualized patient assessments to identify factors affecting adherence to dietary calcium recommendations.

Résumé

Dans le but de déterminer les obstacles à l'observance des apports recommandés en calcium chez les femmes ayant une faible densité minérale osseuse (DMO), quatre sessions de groupes cibles ont été tenues avec 30 femmes postménopausées diagnostiquées comme ayant une faible DMO. Les concepts et thèmes clés ont émergé des transcriptions des discussions. Les participantes étaient conscientes de l'importance du calcium pour la santé de leurs os et s'efforçaient de suivre les apports recommandés en calcium. Plusieurs grands thèmes associés à la capacité de consommer des quantités suffisantes de calcium sont ressortis, notamment les connaissances et l'assurance de prendre les bonnes décisions, le mode de vie et les préférences alimentaires, les effets secondaires et les préoccupations vis-à-vis d'autres problèmes de santé. Les participantes ont dit avoir obtenu de l'information pour être en mesure de prendre des décisions éclairées au sujet de l'apport en calcium, mais que des renseignements contradictoires compliquaient leur compréhension. Les activités quotidiennes ainsi que les préférences alimentaires personnelles et familiales influencent les comportements alimentaires. Les femmes ont déclaré que les effets secondaires, entre autres ceux qui sont liés à la perception de l'intolérance au lactose, les poussaient à restreindre leur apport en calcium. Nos données fournissent de précieux renseignements sur les facteurs perçus par les femmes comme diminuant leur capacité de satisfaire aux apports recommandés en calcium. Pour optimiser la prévention et le traitement de l'ostéoporose, les diététistes devraient centrer leur action sur l’évaluation personnalisée des patientes afin de déterminer les facteurs qui influencent l'observance des apports recommandés en calcium.
