No Money No Time (NMNT) is a culinary nutrition website designed to optimize diet quality. The primary aim was to evaluate the impact of an online targeted nutrition challenge email campaign that encouraged engagement with NMNT and goal setting to improve diet quality and weekly food expenditure. A secondary aim was to assess NMNT engagement. Australian adults ≥18 years were recruited to the eHealth nutrition challenge delivered via weekly emails. Diet quality was assessed using the Healthy Eating Quiz (HEQ) diet quality tool. Engagement was assessed using email open and click-through rates. Intention-to-treat (ITT) analysis was conducted using mixed effects linear regression. Of 481 adults (49.7 ± 13.9 years, 84% female) who enrolled 79 (16%) completed the challenge. ITT results indicated statistically significant 6-week increases in diet quality score (+3.8 points ≤ 0.001, = 0.58) with sub-scale improvements in vegetables (+0.9 points, = 0.01, = 0.32), fruit (+1.2 points, ≤ 0.001, = 0.55), and dairy (+0.9 points, ≤ 0.001, = 0.58). There were significant post-challenge reductions in household spending on takeaway/snacks/coffee of AUD 8.9 per week ( = 0.01, = 0.29), body weight reduction (-0.6 kg, = 0.03, = 0.26), and BMI (-0.2 kg/m = 0.02, = 0.28). The email open rate remained constant at around 67% (56% to 75%), with an average click-through rate of 18% (7.1% to 37.9%). The eHealth nutrition challenge significantly improved diet quality while reducing BMI and money spent on discretionary foods. Strategies to scale the challenge should be tested as an innovative population strategy for improving diet quality, health indicators, and managing household food budgets.
无钱无闲（NMNT）是一个烹饪营养网站，旨在优化饮食质量。主要目的是评估一项在线有针对性的营养挑战电子邮件活动的影响，该活动鼓励参与 NMNT 和设定目标，以改善饮食质量和每周食品支出。次要目的是评估 NMNT 的参与度。通过每周电子邮件向澳大利亚≥18 岁的成年人招募参加电子健康营养挑战。使用健康饮食测验（HEQ）饮食质量工具评估饮食质量。使用电子邮件打开率和点击率来评估参与度。使用混合效应线性回归进行意向治疗（ITT）分析。在 481 名成年人（49.7 ± 13.9 岁，84%为女性）中，有 79 名（16%）完成了挑战。ITT 结果表明，饮食质量评分在 6 周内有统计学意义的增加（+3.8 分，≤0.001， = 0.58），蔬菜（+0.9 分， = 0.01， = 0.32）、水果（+1.2 分，≤0.001， = 0.55）和乳制品（+0.9 分，≤0.001， = 0.58）亚量表也有所改善。挑战后，每周外卖/零食/咖啡的家庭支出减少了 8.9 澳元（ = 0.01， = 0.29），体重减轻了 0.6 公斤（ = 0.03， = 0.26），BMI 降低了 0.2 公斤/米（ = 0.02， = 0.28）。电子邮件打开率保持在 67%左右（56%至 75%），平均点击率为 18%（7.1%至 37.9%）。电子健康营养挑战显著改善了饮食质量，同时降低了 BMI 和可自由支配食品的支出。应测试扩大挑战规模的策略，作为改善饮食质量、健康指标和管理家庭食品预算的创新人群策略。
