Consuming a variety of food groups is a proxy indicator of micronutrient adequacy among women of reproductive age (WRA). This study examined the association between minimum food group production diversity (MFGPD) and minimum dietary diversity for women (MDD-W); and the correlation between food group production diversity (FGPD) and women's dietary diversity (WDD) among lactating mothers in rural Kyankwanzi district, central Uganda.
Lactating mothers residing in subsistence farming households (HH) were recruited by systematic sampling. The outcome variables were WDD and MDD-W. A respondent scored either "1" or "0" if she consumed or did not consume any of the 10 food groups in the previous 24 h, respectively. The WDD was calculated as the total of all food group scores. The respondent was considered to have achieved MDD-W if she consumed ≥ 5 out of the 10 food groups. The main exposure variables were FGPD and MFGPD. The food groups used to classify foods on the farm were the same as the 10 food group classifications used in the MDD-W. The FGPD was calculated as the total of all food group scores on the farm. The MFGPD was achieved if the farm had ≥ 5 of the 10 food groups. The association between FGPD and WDD was tested by Poisson regression analysis. The association between MFGPD and MDD-W was tested by logistic regression analysis. A test was significant at 95% confidence interval(CI) and P value < 0.05.
There was a positive correlation between WDD and FGPD, adjusted β:0.15 (95%CI 0.13-0.16, P < 0.0001). Lactating mothers who achieved MFGPD were more likely to achieve MDD-W, adjusted odds ratio (AOR): of 8.6 (95% CI: 5.6-13.0, P < 0.0001).
The MFGPD is positively associated with MDD-W, while WDD increases as FGPD increases among lactating mothers in the study area. Promoting food production diversity based on food groups has the potential to improve WDD and achieve MDD-W among lactating mothers in the study area.
摄入多种食物类别是育龄妇女（WRA）微量营养素充足的一个替代指标。本研究调查了乌干达中部Kyankwanzi区农村哺乳期母亲的最低食物类别生产多样性（MFGPD）与妇女最低饮食多样性（MDD-W）之间的关联；以及食物类别生产多样性（FGPD）与妇女饮食多样性（WDD）之间的相关性。
通过系统抽样招募居住在自给农业家庭（HH）中的哺乳期母亲。结果变量为WDD和MDD-W。若受访者在前24小时内食用或未食用10种食物类别中的任何一种，则分别记为“1”或“0”。WDD计算为所有食物类别得分的总和。如果受访者食用了10种食物类别中的≥5种，则认为其达到了MDD-W。主要暴露变量为FGPD和MFGPD。用于对农场食物进行分类的食物类别与MDD-W中使用的10种食物类别分类相同。FGPD计算为农场所有食物类别得分的总和。如果农场拥有10种食物类别中的≥5种，则达到了MFGPD。通过泊松回归分析检验FGPD与WDD之间的关联。通过逻辑回归分析检验MFGPD与MDD-W之间的关联。检验在95%置信区间（CI）和P值<0.05时具有显著性。
WDD与FGPD之间存在正相关，调整后的β：0.15（95%CI 0.13 - 0.16，P<0.0001）。达到MFGPD的哺乳期母亲更有可能达到MDD-W，调整后的优势比（AOR）：为8.6（95%CI：5.6 - 13.0，P<0.0001）。
在研究区域的哺乳期母亲中，MFGPD与MDD-W呈正相关，而随着FGPD的增加WDD也增加。基于食物类别的促进食物生产多样性有可能改善研究区域哺乳期母亲的WDD并实现MDD-W。
