Evaluation of the Community-Based Chronic Disease Prevention Program Meta Salud in Northern Mexico, 2011–2012
Initially 184 individuals consented to participate in the study; of these, the study team had complete baseline data for 125 participants, complete data at baseline and conclusion for 112 participants, and complete data at baseline, conclusion, and 3-month follow-up for 85 participants. At baseline, we had anthropometric data for 177 participants (data unavailable for 7 participants), laboratory data for 129 participants (data unavailable for 55 participants), and completed questionnaires for 171 participants (data unavailable for 13 participants). At the conclusion of the intervention, we obtained complete data for 114 participants; we had anthropometric data for 176 participants (data unavailable for 8 participants); laboratory data for 118 participants (data unavailable for 66 participants), and completed questionnaires for 176 participants (data unavailable for 8 participants). At 3-month follow-up, we obtained complete data for 88 participants; we had anthropometric data for 149 participants (data unavailable for 35 participants); laboratory data for 91 participants (data unavailable for 93 participants), and completed questionnaires for 152 participants (data unavailable for 32 participants).
