More efficient way search for multiple objects in array

I am currently using a for loop and multiple if statements to count the number of records that match a string.

for (var i = 0; i < DailyLogs.length; i++) {
  if (DailyLogs[i].created_at >= this.state.startMonth && DailyLogs[i].created_at <= this.state.finishMonth) {
    if (DailyLogs[i].created_by_id === "37aa0778-c148-4c04-b239-18885d46a8b0" ) { md1++; }
    if (DailyLogs[i].created_by_id === "869a7967-ffb3-4a20-b402-ad6d514472de" ) { md2++; }
    if (DailyLogs[i].created_by_id === "92c0f155-ce82-4b50-821f-439428c517a3" ) { md3++; }
    if (DailyLogs[i].created_by_id === "aa9eb0f2-35af-469a-8893-fc777b444bed" ) { md4++; }
    if (DailyLogs[i].created_by_id === "967d63ea-492c-4475-8b08-911be2d0bf22" ) { md5++; }
    if (DailyLogs[i].created_by_id === "47ec8d60-1fa2-4bf5-abc8-34df6bd53079" ) { md6++; }
    if (DailyLogs[i].created_by_id === "92c0f155-ce82-4b50-821f-439428c517a3" ) { md7++; }
  }
}

Is there a better way to do this, apart from having multiple if statements, or perhaps shorting this somehow.
