Multivariat analysis results showed that dominantly associated with exclusive breastfeeding during COVID-19 pandemic was breastfeeding intention [aOR=17.3; 95%CI (4.222 – 71.069), followed by household income level [aOR=4.2; 95%CI (1.550 – 11.741)] and infant’s age [aOR=2.4; 95%CI (1.116 – 5.243)]. Mothers with breastfeeding intention since pregnancy had 17.3 higher odd of exclusive breastfeeding practice than mothers who had not intention to breastfeeding.

Studi potong lintang melalui survei daring dilakukan pada ibu dengan bayi usia di bawah 6 bulan di Indonesia selama 2 November 2020 - 8 Februari 2021. Chi-square/Fisher-test digunakan untuk menganalisis hubungan antara masing-masing faktor dengan praktik pemberian ASI eksklusif. Uji regresi logistik ganda digunakan untuk mengetahui faktor dominan praktik ASI eksklusif. Sebagian besar subjek berusia 18-34 tahun (90,7%), berpendidikan tinggi (86,7%), tergolong berpenghasilan menengah ke atas (87,1%), tinggal di Pulau Jawa (83,1), memiliki bayi berusia ≤ 4 bulan (76,2%), dan memiliki bayi laki-laki (51,2%). Proporsi subjek yang menyusui secara ekslusif adalah sebesar 79.0%. Faktor yang berhubungan secara signifikan dengan praktik pemberian ASI eksklusif selama pandemi COVID-19 di Indonesia adalah tingkat pendapatan rumah tangga [OR = 2,6; 95% CI (1,194 - 5,839)], status perkawinan [OR = 4,9, 95% CI (3,842 - 6,301)] dan niat menyusui [OR = 12,8; 95% CI (3,906 - 42,459)]. Hasil analisis multivariat menunjukkan bahwa factor dominan pemberian ASI eksklusif selama pandemi COVID-19 adalah niat menyusui [aOR = 17,3; 95% CI (4.222 - 71.069), diikuti tingkat pendapatan rumah tangga [aOR = 4.2; 95% CI (1.550 - 11.741)] dan usia bayi [aOR = 2.4; 95% CI (1.116 - 5.243)]. Ibu yang memiliki niat untuk menyusui sejak kehamilan berpeluang 17,3 lebih besar memberikan ASI eksklusif dibandingkan ibu yang tidak berniat menyusui.

Analisis data survei lebih lanjut diperlukan untuk menggali lebih dalam tentang perubahan pengalaman ibu, seperti gaya hidup sehari-hari, keuangan, akses dan pemanfaatan layanan kesehatan, terutama pada periode pandemi selanjutnya. Selain itu, pengetahuan, kesadaran, sikap atau faktor individu / internal lain yang terkait dengan keputusan pemberian ASI Eksklusif perlu dikaji untuk mendapatkan hasil yang lebih komprehensif.
